(footprint) may be different. Install the EQ7 drive in an environment that satisfies the requirements. TECO-Westinghouse Motor Company strongly recommends installing inverters in a panel for safety reasons, in particular, when installing the ones that have an enclosure rating of IP00.
Page 16  Storage environment The storage environment in which the inverter is stored after purchase is different from the operation environment. For details, refer to the EQ7 DRIVE User's Manual, Chapter 2.  Wiring precautions (1) Route the wiring of the control circuit terminals as far from the wiring of the main circuit as possible. Otherwise electric noise may cause malfunctions.
Page 17  Precautions for connection of peripheral equipment (1) Phase-advancing capacitors for power factor correction Do not mount a phase-advancing capacitor for power factor correction in the inverter's input (primary) or output (secondary) circuit. Mounting it in the input (primary) circuit takes no effect. To correct the inverter power factor, use an optional DC reactor (DCR).
Page 18 (5) Molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) Install a recommended MCCB or RCD/ELCB (with overcurrent protection) in the primary circuit of the inverter to protect the wiring. Since using an MCCB or RCD/ELCB with a lager capacity than recommended ones breaks the protective coordination of the power supply system, be sure to select recommended ones.

Page 20 • From the system's safety point of view, it is recommended to employ such a sequence that shuts down the magnetic contactor (MC) in the inverter input circuit with an alarm output signal ALM issued on inverter's programmable output terminals. The sequence minimizes the secondary damage even if the inverter breaks.
Page 21 (2) If induction or radio noise generated from the inverter affects other devices: - Isolate the main circuit wires from the control circuit wires and other device wires. - Put the main circuit wires through a metal conduit pipe, and connect the pipe to the ground near the inverter. - Install the inverter into the metal panel and connect the whole panel to the ground.
Page 22: Precautions In Running Inverters
If the power transmission mechanism uses an oil-lubricated gearbox or speed changer/reducer, then continuous operation at low speed may cause poor lubrication. Avoid such operation.  Synchronous motors It is necessary to take special measures suitable for this motor type. Contact your TECO-Westinghouse Motor Company representative for details.  Single-phase motors Single-phase motors are not suitable for inverter-driven variable speed operation.
Page 23  High-speed motors If the reference frequency is set to 120 Hz or higher to drive a high-speed motor, test-run the combination of the inverter and motor beforehand to check it for the safe operation. Precautions for use on single-phase power An inverter is a device that converts alternating current of the input line to direct current via the ac-to-dc rectifier and then converts it to alternating current via the dc-to-ac switching inverter circuit in order to output the required alternating current.

Page 25  When employing external cooling In external cooling, the heat sink, which dissipates about 70% of the total heat (total loss) generated into air, is situated outside the equipment or the panel. The external cooling, therefore, significantly reduces heat radiating inside the equipment or panel. To employ external cooling for inverters (except DCR built-in type) of 40 HP or below, use the mounting adapter for external cooling (option);...

Page 32 Before removal of clip-off sections After removal of clip-off sections Wiring Guide (e.g. EQ7-4025-C) (8) In some types of inverters, the wires from the main circuit terminal block cannot be routed straight into the terminal. Route such wires as shown below so that the front cover can be reinstalled. (9) For inverters of 900 and 1000 HP, two L2/S input terminals are arranged vertically to the terminal block.
Page 33 • When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of each pair of power lines to inverters. Use the recommended devices within the recommended current capacity.

Page 37 2) Connecting other external devices A DC link bus of other inverter(s) or a PWM converter is connectable to these terminals. When you need to use the DC link bus terminals P(+) and N(-), consult your TECO-Westinghouse Motor Company representative.
Page 38 125 HP or above for 460 V) The standard EQ7 series accepts DC-linked power input in combination with a PWM converter. Inverters of 60 HP or above for 230 V and those of 125 HP or above for 460 V, however, contain AC-driven components such as AC fans. To supply AC power to those components, exchange the CN R and CN W connectors as shown below and connect the AC power line to the auxiliary fan power input terminals (R1, T1).
Page 39 To remove each of the jumpers, pinch its upper side between your fingers, unlock its fastener, and pull it up. When mounting it, fit the jumper over the connector until it snaps into place. Figure 2.7 Inserting/Removing the Jumpers Main circuit power input terminals L1/R, L2/S, and L3/T (three-phase input) The three-phase input power lines are connected to these terminals.
Page 40 When connecting a PWM converter with an inverter, do not connect the power supply line directly to terminals R0 and T0. If a PWM is to be connected, insert an isolation transformer or auxiliary B contacts of a magnetic contactor at the power supply side. For connection examples at the PWM converter side, refer to the PWM Converter Instruction Manual.
Page 41 2.3.5 Wiring for control circuit terminals This section shows connection diagrams with the Enable input function used. In general, the covers of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main circuit, the insulation of the cover might break down, which would expose the signal wire to a high voltage of the main circuit.
Page 42 Table 2.7 lists the symbols, names and functions of the control circuit terminals. The wiring to the control circuit terminals differs depending upon the setting of the function codes, which reflects the use of the inverter. Route wires properly to reduce the influence of noise.

Page 95: Details Of Function Codes
4.2 Details of Function Codes This section provides the details of the function codes. The descriptions are, in principle, arranged in the order of function code groups and in numerical order. However, highly relevant function codes are collectively described where one of them first appears.
Page 96 Configuring a reference frequency [ 1 ] Using keys (F01 = 0 (factory default) or 8) (1) Set function code F01 at "0" or "8" ( keys on keypad). This cannot be done when the keypad is in Programming or Alarm mode. To enable frequency setting using the keys, first place the keypad in Running mode.
Page 97 The table below lists the available command sources and their symbols. Available Command Sources Symbol Command source Symbol Command source Symbol Command source PID keypad HAND Keypad MULTI Multi-frequency PID-HAND command PID command 1 Terminal [12] PID-P1 (Analog command) PID command 2 Terminal [C1] RS485-1 RS-485 (Port 1) *...
Page 98  Gain and bias If F01 = 3 (the sum of [12] + [C1] is enabled), the bias and gain are independently applied to each of the voltage and current inputs given to terminals [12] and [C1], and the sum of the two values is applied as the reference frequency.
Page 99 In the case of bipolar input (terminal [12] with C35 = 0, terminal [V2] with C45 = 0) Setting C35 and C45 data to "0" enables terminal [12] and [V2] to be used for bipolar input (-10 V to +10 V) respectively.
Page 100  Specifying the initial value for the UP/DOWN control Specify the initial value to start the UP/DOWN control. Data for H61 Initial value to start the UP/DOWN control Mode fixing the value at "0": The inverter automatically clears the value to "0" when restarted (including powered ON).
Page 101 [ 4 ] Using pulse train input (F01 = 12) The EQ7 can accommodate different types of pulse train inputs. Select the type of signal (d59) and scaling (d62, d63) as described here.  Selecting the pulse train input format (d59) A pulse train in the format selected by the function code d59 can give a frequency command to the inverter.
Page 102  Pulse count factor 1 (d62), Pulse count factor 2 (d63) For the pulse train input, function codes d62 (Command (Pulse rate input), (Pulse count factor 1)) and d63 (Command (Pulse rate input), (Pulse count factor 2)) define the relationship between the input pulse rate and the frequency command (reference).
Page 103 Operation Method F02 selects the source that specifies a run command. Data for F02 Run Command Description Keypad Enables the , and keys to run the motor in the forward and reverse directions, and stop the motor. Terminal command FWD or REV Enables input terminal commands FWD and REV to run the motor in the forward and reverse directions, and stop the motor.
Page 104 Maximum Frequency 1 F03 specifies the maximum frequency to limit the output frequency. Specifying the maximum frequency exceeding the rating of the equipment driven by the inverter may cause damage or a dangerous situation. Make sure that the maximum frequency setting matches the equipment rating. - Data setting range: 25.0 to 500.0 (Hz) •...

Page 106 In vector control, current feedback control is performed. In the current feedback control, the current is controlled with the difference between the motor induced voltage and the inverter output voltage. For a proper control, the inverter output voltage should be sufficiently higher than the motor induced voltage. Generally, the voltage difference is about 20 V for 230 V series, about 40 V for 460 V series.
Page 107 Under vector control without speed sensor Under vector control with speed sensor  Acceleration/deceleration time Function code Switching factor of acceleration/deceleration time Acceleration/ deceleration time ( Refer to the descriptions of E01 to E07.) time time The combinations of ON/OFF states of the Acceleration/ two terminal commands RT2 and RT1 offer deceleration time 1...
Page 108  Acceleration/Deceleration pattern (H07) H07 specifies the acceleration and deceleration patterns (patterns to control output frequency). Acceleration/ Data for Function deceleration Motion code pattern － Linear The inverter runs the motor with the constant acceleration and deceleration. － S-curve To reduce an impact that Fixed: (Fixed) acceleration/deceleration...
Page 109 Curvilinear acceleration/deceleration Acceleration/deceleration is linear below the base frequency (constant torque) but it slows down above the base frequency to maintain a certain level of load factor (constant output). This acceleration/deceleration pattern allows the motor to accelerate or decelerate with its maximum performance. The figures at left show the acceleration characteristics.
Page 110 Electronic Thermal Overload Protection for Motor 1 F10 to F12 (Select motor characteristics, Overload detection level, and Thermal time constant) F10 through F12 specify the thermal characteristics of the motor for its electronic thermal overload protection that are used to detect overload conditions of the motor. Upon detection of overload conditions of the motor, the inverter ceases outputting and issues a motor overload alarm to protect motor 1.

Page 113 • Under vector control without speed sensor (F42 = 1 or 5) Description Data for F14 Auto search disabled Auto search enabled 0: Trip immediately As soon as the DC link bus voltage drops below the undervoltage detection level due to a momentary power failure, the inverter issues undervoltage alarm lu and shuts down its output so that the motor enters a coast-to-stop state.
Page 114 If you enable the "Restart mode after momentary power failure" (Function code F14 = 3, 4, or 5), the inverter automatically restarts the motor running when the power is recovered. Design the machinery or equipment so that personnel safety is ensured after restarting. Otherwise an accident could occur.
Page 115 During a momentary power failure, the motor slows down. After power is restored, the inverter restarts at the frequency just prior to power failure. Then, the current limiting function works and the output frequency of the inverter automatically decreases. When the output frequency matches the motor speed, the motor accelerates up to the output frequency.
Page 116  Restart mode after momentary power failure (Allowable momentary power failure time) (H16) H16 specifies the maximum allowable duration (0.0 to 30.0 seconds) from an occurrence of a momentary power failure (undervoltage) until the inverter is to be restarted. Specify the coast-to-stop time which the machine system and facility can tolerate.
Page 117 Factory default: By factory default, H13 is set to a matched value for the standard motor (see Table A in Section 5.1 "Function Code Tables"). Basically, it is not necessary to change H13 data. However, if the long restart time causes deteriorated performance or causes any other problem, reduce the setting to about a half of the default value, ensuring that no alarm occurs.
Page 118 Even if selecting "Trip after decelerate-to-stop" or "Continue to run," the inverter may not be able to do so when the load's inertia is small or the load is heavy, due to undervoltage caused by a control delay. In such a case, when "Trip after decelerate-to-stop" is selected, the inverter allows the motor to coast to a stop;...
Page 119 Bias (Frequency command 1) (Refer to F01.) page 4-26 F20 to F22 DC Braking 1 (Braking starting frequency, Braking level, and Braking time) DC Braking (Braking response mode) F20 through F22 specify the DC braking that prevents motor 1 from running by inertia during decelerate-to-stop operation.
Page 120 It is also possible to use an external digital input signal as an "Enable DC braking" terminal command DCBRK. As long as the DCBRK command is ON, the inverter performs DC braking, regardless of the braking time specified by F22. (...
Page 121  Starting frequency 1 (Holding time) (F24) Data setting range: 0.00 to 10.00 (s) F24 specifies the holding time for the starting frequency 1.  Stop frequency (F25) Data setting range: 0.0 to 60.0 (Hz) F25 specifies the stop frequency at the stop of the inverter. Under V/f control, even if the stop frequency is set at 0.0 Hz, the inverter stops at 0.1 Hz.

Page 126  V/f characteristics The EQ7 series of inverters offers a variety of V/f patterns and torque boosts, which include V/f patterns suitable for variable torque load such as general fans and pumps and for constant torque load (including special pumps requiring high starting torque).
Page 127 • Auto torque boost (F37 = 2, 5) If the auto torque boost is selected, the inverter automatically optimizes the output voltage to fit the motor with its load. Under light load, the inverter decreases the output voltage to prevent the motor from over-excitation. Under heavy load, it increases the output voltage to increase the output torque of the motor.

Page 129  Torque limiter levels specified via communications link (S10, S11) The torque limiter levels can be changed via the communications link. Function codes S10 and S11 exclusively reserved for the communications link respond to function codes F40 and F41.  Switching torque limiters The torque limiters can be switched by the function code setting and the terminal command TL2/TL1 ("Select torque limiter level 2/1") assigned to any of the digital input terminals.
Page 130 Under vector control without/with speed sensor (F42 = 5, 6) If the inverter’s output torque exceeds the specified levels of the torque limiters (F40, F41, E16, E17, and E61 to E63), the inverter controls the speed regulator's output (torque command) in speed control or a torque command in torque control in order to limit the motor-generating torque.
Page 131  Torque Limiter (Target quadrants) (H75) H75 selects the configuration of target quadrants (Drive/brake, Forward/reverse rotation) in which the specified torque limiter(s) is activated, from "Drive/brake torque limit," "Same torque limit for all four quadrants," and "Upper/lower torque limits" shown in the table below. Data for H75 Target quadrants 0: Drive/brake...
Page 132 Data for H75 Target quadrants Pattern 3 • If the value of torque limiter A is less than that of torque limiter B, torque limiter A applies to both the upper and lower limits. • Selecting the "Upper/lower torque limits" may cause reciprocating oscillation between the upper and lower limit values, depending upon a small difference between the upper and lower limits, a slow response from the speed control sequence, and other conditions.
Page 133  Torque limiter (Operating conditions) (H73) H73 specifies whether the torque limiter is enabled or disabled during acceleration/deceleration and running at constant speed. Data for H73 During accelerating/decelerating During running at constant speed Enable Enable Disable Enable Enable Disable The torque limiter and current limiter are very similar in function. If both are activated concurrently, they may conflict with each other and cause hunting (undesirable oscillation of the system).

Page 135  Vector control without speed sensor This control estimates the motor speed based on the inverter's output voltage and current to use the estimated speed for speed control. It also decomposes the motor drive current into the exciting and torque current components, and controls each of those components in vector.
Page 136 F43, F44 Current Limiter (Mode selection, Level) H12 (Instantaneous Overcurrent Limiting (Mode selection)) When the output current of the inverter exceeds the level specified by the current limiter (F44), the inverter automatically manages its output frequency to prevent a stall and limits the output current. The default setting of the current limiter is 130% and 160% for VT and CT mode inverters, respectively.
Page 137 F50 to F52 Electronic Thermal Overload Protection for Braking Resistor (Discharging capability, Allowable average loss and Resistance) These function codes specify the electronic thermal overload protection feature for the braking resistor. Set the discharging capability, allowable average loss and resistance to F50, F51 and F52, respectively. These values are determined by the inverter and braking resistor models.
Page 138  Allowable average loss (F51) The allowable average loss refers to a tolerance for motor continuous operation, which is obtained based on the %ED (%) and motor rated capacity (HP). Data for F51 Function 0.001 to 99.99 0.001 to 99.99 (kW) During deceleration: %ED(%) ÷...

Selection of normal/inverse operation for Final operation frequency command 1 (C53) – 0: Normal operation Normal – 1: Inverse operation Inverse When the process control is performed by the PID control facility integrated in the inverter, the IVS is used to switch the PID processor output (reference frequency) between normal and inverse, and has no effect on any normal/inverse operation selection of the manual frequency setting.
Page 149  Force to stop -- STOP (Function code data = 30) Turning this terminal command OFF causes the motor to decelerate to a stop in accordance with the H56 data (Deceleration time for forced stop). After the motor stops, the inverter enters the alarm state with the alarm er6 displayed.

Page 154  Enable battery operation -- BATRY (Function code data = 59) Turning this terminal command ON cancels the undervoltage protection so that the inverter runs the motor with battery power under an undervoltage condition. When BATRY is assigned to any digital input terminal, the inverter trips after recovery from power failure just as F14 = 1 regardless of F14 setting.

Page 178 4.2.4 P codes (Motor 1 Parameters) The EQ7 drives the motor under V/f control, dynamic torque control, vector control without speed sensor, or vector control with speed sensor, which can be selected with function codes. To use the integrated automatic control functions such as auto torque boost, torque calculation monitoring, auto-energy saving operation, torque limiter, automatic deceleration (anti-regenerative control), auto search for idling motor speed, slip compensation, torque vector control, droop control, and overload stop, it is necessary to build a motor model in the inverter by specifying proper motor parameters including the motor capacity and rated...
Page 179 Motor 1 (Auto-tuning) The inverter automatically detects the motor parameters and saves them in its internal memory. Basically, it is not necessary to perform tuning when using a HP rating motor with a standard connection with the inverter. There are three types of auto-tuning as listed below. Select appropriate one considering the limitations in your equipment and control mode.
Page 180 P05, A19 Motor 1 / 2 (Online tuning) Long run under "Dynamic torque control" or "Slip compensation control" causes motor temperature change, varying the motor parameters. This changes the motor speed compensation amount, resulting in motor speed deviation from the initial rotating speed. Enabling online tuning identifies motor parameters covering the motor temperature change to decrease the motor speed fluctuation.
Page 181 P10 determines the response time for slip compensation. Basically, there is no need to modify the default setting. If you need to modify it, consult your TECO-Westinghouse Motor Company representatives. Function codes...
Page 182 P53, P54 Motor 1 (%X correction factors 1 and 2) P53 and P54 specify the factors to correct fluctuations of leakage reactance (%X). Basically, there is no need to modify the setting. Motor 1 (Torque current under vector control) P55 specifies the rated torque current under vector control without/with speed sensor. The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.

Page 194: Motor And Application Specific Settings
Chapter 8 Motor and Application Specific Settings It is essential that before running the motor, the motor nameplate data matches the motor data in the EQ7 drive. 8.1 Set Motor Name Plate Data (P02, P03, F11) Motor 1 (Capacity) The nominal motor rated capacity is set at the factory. Please verify that the motor name plate data matches the motor rated capacity shown in parameter P02.
Page 195: Acceleration And Deceleration Time
8.2 Acceleration and Deceleration Time (F07 / F08) Acceleration and Deceleration times directly control the system dynamic response. In general, the longer the acceleration and deceleration time, the slower the system response, and the shorter time, the faster the response. An excessive amount of time can result in sluggish system performance while too short of a time may result in system instability.
Page 196: Torque Boost Setting
8.3 Torque Boost (F09, Default 0.1) IMPORTANT: PARAMETER IS REQUIRED TO BE CHANGED FOR CONSTANT TORQUE APPLICATIONS. This parameter sets the relationship between output frequency and output voltage. Constant torque applications have the same torque requirements at low speed as well as at high speed. See parameter F37 to select Load Selection / Auto Torque Boost.
Page 197: Load Selection / Auto Torque Boost / Auto Energy Saving Operation 1
 V/f characteristics The EQ7 series of inverters offers a variety of V/f patterns and torque boosts, which include V/f patterns suitable for variable torque load such as general fans and pumps and for constant torque load (including special pumps requiring high starting torque).
Page 198 When the variable torque V/f pattern is selected (F37 = 0 or 3), the output voltage may be low at a low frequency zone, resulting in insufficient output torque, depending on the characteristics of the motor and load. In such a case, it is recommended to increase the output voltage at the low frequency zone using the non-linear V/f pattern.

8.5 Reset EQ7 back to Factory Default Parameter H03 Data Initialization H03 initializes the current function code data to the factory defaults or initializes the motor parameters. To change the H03 data, it is necessary to press the keys or keys (simultaneous keying).
Page 200: What Is Pid Control
Chapter 9 Using PID Control for Constant Flow / Pressure Applications 9.1 What is PID Control? The PID function in the EQ7 drive can be used to maintain a constant process variable such as pressure, flow, temperature by regulating the output frequency (motor speed). A feedback device (transducer) signal is used to compare the actual process variable to a specified setpoint.
Page 201: Connect Transducer Feedback Signal
PID control (Mode Select) PID control can be enabled by setting parameter J01 to ‘1’ Setting Range: 0 - 3 No operation; PID Operation disabled Forward operation: PID operation enabled, motor speeds increases when feedback signal is smaller than set-point (most fan and pump applications) Reverse operation: PID operation enabled, motor slows down when feedback signal is smaller than set-point (e.g.
