Page 188: Wiring For Control Circuit Terminals
5.1 Mounting and Wiring the Inverter 5.1.7 Wiring for control circuit terminals 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.

[EN2] Enable input 2 (2) These terminals are exclusively used for the SOURCE mode input and cannot be switched to the SINK mode input. (3) If input to either one of [EN1] and [EN2] is OFF, the inverter issues an alarm (ECF).

Page 327 • When you start accessing the reference frequency or any other parameter with the key, the least significant digit on the display blinks, indicating that the cursor lies in the least significant digit. Holding down the key changes data in the least significant digit and generates a carry, while the cursor remains in the least significant digit.
Page 328 6.3 Details of Function Codes Switching between frequency command 1 (F01) and 2 (C30) Frequency command 1 (F01) and 2 (C30) can be switched by the external input signal Hz2/Hz1 ("Select frequency command 2/1") assigned to any digital input terminal. For details about Hz2/Hz1, refer to the description of E01 through E07 (data = 11).
Page 329 Gain and bias Input Frequency command 1 (F01) Frequency command 2 (C30) terminal [12] [C1] [V12] 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 330 6.3 Details of Function Codes In the case of unipolar input (terminal [12] with C35 = 1, terminal [C1], terminal [V2] with C45 = 1) As shown in the graphs above, the relationship between the analog input and the reference frequency specified by frequency command 1 (F01) is determined by points "A"...
Page 331 (Point B) Frequency command 1 (F01), Frequency command 2 (C30) To specify the maximum frequency equal to the reference frequency for an analog input being at 5 V, set the gain to 100% (C32 = 100). Since 5 V is the gain base point and it is equal to 50% of 10 V (full scale of terminal [12]), set the gain base point to 50% (C34 = 50).
Page 332 6.3 Details of Function Codes [ 3 ] Using digital input signals UP/DOWN (F01 = 7) When UP/DOWN control is selected for frequency setting, turning the terminal command UP or DOWN ON causes the output frequency to increase or decrease, respectively, within the range from 0 Hz to the maximum frequency as listed below.
Page 333 3-wire operation with external input signals (digital input terminal commands) The default setting of the FWD and REV are 2-wire. Assigning the terminal command HLD self-holds the forward FWD or reverse REV run command, to enable 3-wire inverter operation. For details about HLD, refer to E01 to E07 (data = 6). Short-circuiting the HLD-assigned terminal and [CM] (i.e., when HLD is ON) self-holds the first FWD or REV at its rising edge.
Page 334 6.3 Details of Function Codes F04, F05 Base Frequency 1, Rated Voltage at Base Frequency 1, Maximum Output Voltage 1 H50, H51 (Non-linear V/f Pattern 1, Frequency and Voltage) H52, H53 (Non-linear V/f Pattern 2, Frequency and Voltage) These function codes specify the base frequency and the voltage at the base frequency essentially required for running the motor properly.

Page 337 S-curve acceleration/deceleration To reduce an impact that acceleration/deceleration would make on the machine, the inverter gradually accelerates or decelerates the motor in both the starting and ending zones of acceleration or deceleration. Two types of S-curve acceleration/deceleration rates are available; applying 5% (weak) and 10% (strong) of the maximum frequency to all of the four inflection zones.
Page 338 6.3 Details of Function Codes 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.

Page 343 Restart mode after momentary power failure (Basic operation: Auto search disabled) The inverter recognizes a momentary power failure upon detecting the condition that DC link bus voltage goes below the undervoltage level, while the inverter is running. If the load of the motor is light and the duration of the momentary power failure is extremely short, the voltage drop may not be great enough for a momentary power failure to be recognized, and the motor may continue to run uninterrupted.
Page 344 6.3 Details of Function Codes • When the power is restored, the inverter will wait 2 seconds for input of a run command. However, if the allowable momentary power failure time (H16) has elapsed after the power failure was recognized, the inverter will no longer wait 2 seconds for input of a run command and start operation in the normal starting sequence.
Page 345 Restart mode after momentary power failure (Basic operation: Auto search enabled) Auto search for idling motor speed will become unsuccessful if it is done while the motor retains residual voltage. It is, therefore, necessary to leave the motor for the time (auto search delay time) enough to discharge the residual voltage.
Page 346 6.3 Details of Function Codes 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 restart of the inverter. Specify the coast-to-stop time during which the machine system and facility can be tolerated.
Page 347 Restart mode after momentary power failure (Restart time) (H13) H13 specifies the time period from an occurrence of a momentary power failure until the restart of the inverter. (When auto search is enabled, H46 (Auto search delay time 2) applies.) If the inverter starts the motor while motor’s residual voltage is still in a high level, a high inrush current may flow or an overvoltage alarm may occur due to an occurrence of temporary regeneration.
Page 348 6.3 Details of Function Codes Restart after momentary power failure (Continuous running level) (H15) Continuity of running (P and I) (H92, H93) • Trip after decelerate-to-stop (F14 = 2) If a momentary power failure occurs when F14 is set to "2" (Trip after decelerate-to-stop), the inverter enters the control sequence of the decelerate-to-stop when the DC link bus voltage drops below the continuous running level specified by H15.
Page 349 F15, F16 Frequency Limiter (High and Low) H63 (Low Limiter, Mode selection) Frequency Limiter (High and Low) (F15, F16) F15 and F16 specify the upper and lower limits of the output frequency or reference frequency, respectively. The object to which the limit is applied differs depending on the control system.

F20 to F22 DC Braking 1 (Braking starting frequency, Braking level and Braking time) DC Braking (Braking response mode) These function codes specify the DC braking that prevents motor 1 from running by inertia during decelerate-to-stop operation.
Page 351 It is also possible to use an external digital input signal as the terminal command DCBRK ("Enable DC braking"). As long as the DCBRK is ON, the inverter performs DC braking, regardless of the braking time specified by F22. For details about DCBRK, refer to E01 through E07 (data = 13). Turning the DCBRK ON even when the inverter is in a stopped state activates the DC braking.
Page 352 6.3 Details of Function Codes F23 to F25 Starting Frequency 1, Starting Frequency 1 (Holding time), and Stop Frequency At the startup of an inverter, the initial output frequency is equal to the starting frequency. The inverter stops its output when the output frequency reaches the stop frequency. Set the starting frequency to a level at which the motor can generate enough torque for startup.
Page 353 F26, F27 Motor Sound (Carrier frequency and Tone) H98 (Protection/Maintenance Function, Mode selection) Motor Sound (Carrier frequency) (F26) F26 controls the carrier frequency so as to reduce an audible noise generated by the motor or electromagnetic noise from the inverter itself, and to decrease a leakage current from the main output (secondary) wirings.

Page 358 V/f pattern (factory default). V/f characteristics The FRENIC-AQUA series of inverters offer 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 359 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.
Page 360 6.3 Details of Function Codes • Auto torque boost This function automatically optimizes the output voltage to fit the motor with its load. Under light load, auto torque boost 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 361 F40, F41 Torque Limiter 1 (Driving, Braking) E16 and E17 (Torque Limiter 2 (Driving, Braking)) H76 (Torque Limiter for Braking, Frequency increment limit) If the inverter’s output torque exceeds the specified levels of the torque limiters (F40, F41, E16 and E17), the inverter controls the output frequency and limits the output torque for preventing a stall.
Page 362 6.3 Details of Function Codes Torque limiter for braking (Frequency increment limit) (H76) Data setting range: 0.0 to 120.0 (Hz) H76 specifies the increment limit of the frequency in limiting torque for braking. The factory default is 5.0 Hz. If the increasing frequency during braking reaches the limit value, the torque limiters no longer function, resulting in an overvoltage trip.

Page 364 6.3 Details of Function Codes Dynamic torque vector control To get the maximal torque out of a motor, this control calculates the motor torque matched to the load applied and uses it to optimize the voltage and current vector output. Selecting this control automatically enables the auto torque boost and slip compensation function so that it is effective for improving the system response to external disturbances such as load fluctuation, and the motor speed control accuracy.
Page 365 F43, F44 Current Limiter (Mode selection and 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.
Page 366 6.3 Details of Function Codes • If an excessive load is applied when the current limiter operation level is set extremely low, the inverter will rapidly lower its output frequency. This may cause an overvoltage trip or dangerous turnover of the motor rotation due to undershooting.

6.3.4 P codes (Motor 1 parameters) To use the integrated automatic control functions such as auto torque boost, torque calculation monitoring, torque limiter, automatic deceleration (anti-regenerative control), auto search for idling motor speed, slip compensation, and torque vector control, it is necessary to build a motor model in the inverter by specifying proper motor parameters including the motor capacity and rated current.
Page 424 6.3 Details of Function Codes Motor 1 (Auto-tuning) The inverter automatically detects the motor constants and saves them as parameters in its internal memory. Basically, no tuning is required as long as a Fuji standard motor is used with standard connection with the inverter. There are two types of auto-tuning as listed below.
Page 425 Motor 1 (Online tuning) Long run under "Dynamic torque vector 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 rpm. Enabling online tuning (P05 = 1) identifies motor parameters covering the motor temperature change to decrease the motor speed fluctuation.
Page 426 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 Fuji Electric representatives. For details about slip compensation control, refer to the description of F42.

Page 444 6.3 Details of Function Codes H04, H05 Auto-reset (Times and Reset interval) H04 and H05 specify the auto-reset function that makes the inverter automatically attempt to reset the tripped state and restart without issuing an alarm output (for any alarm) even if any protective function subject to reset is activated and the inverter enters the forced-to-stop state (tripped state).
Page 445 <Operation timing scheme> • In the figure below, normal operation restarts in the 4th retry. • In the figure below, the inverter fails to restart normal operation within the number of reset times specified by H04 (in this case, 3 times (H04 = 3)), and issues the alarm output (for any alarm) ALM.

This signal can be used to make the cooling system of peripheral equipment interlocked for an ON/OFF control Acceleration/Deceleration Pattern (Refer to F07.)
Page 447 Auto search for idling motor speed Starting the inverter (with a run command ON, BX OFF, auto-reset, etc.) with STM being ON searches for the idling motor speed for a maximum of 1.2 seconds to run the idling motor without stopping it. After completion of the auto search, the inverter accelerates the motor up to the reference frequency according to the frequency command and the preset acceleration time.
Page 448 6.3 Details of Function Codes Depending on the motor characteristics, however, it may take time for residual voltage to disappear (due to the secondary thermal time constant of the motor). In such a case, the inverter starts the motor with the residual voltage remaining, which will cause an error in the speed search and may result in occurrence of an inrush current or an overvoltage alarm.
Page 449 H26, H27 Thermistor (for motor) (Mode selection and Level) These function codes specify the PTC (Positive Temperature Coefficient) thermistor embedded in the motor. The thermistor is used to protect the motor from overheating or output an alarm signal. Thermistor (for motor) (Mode selection) (H26) H26 selects the function operation mode (protection or alarm) for the PTC thermistor as shown below.
Page 450 6.3 Details of Function Codes Connect the PTC thermistor as shown below. The voltage obtained by dividing the input voltage on terminal [C1] with a set of internal resistors is compared with the detection level voltage specified by H27.

Page 453 Capacitance measurement of DC link bus capacitor (H42) Calculating the capacitance of DC link bus capacitor - The discharging time of the DC link bus capacitor depends largely on the inverter's internal load conditions, e.g. options attached or ON/OFF of digital I/O signals. If actual load conditions are so different from the ones at which the initial/reference capacitance is measured that the measurement result falls out of the accuracy level required, then the inverter does not perform measuring.
Page 454 6.3 Details of Function Codes • Ensure that transistor output signals ([Y1] to [Y4]) and relay output signals ([Y5A] - [Y5C], and [30A/B/C]) will not be turned ON. • Disable the RS-485 communications link. If negative logic is specified for the transistor output and relay output signals, they are considered ON when the inverter is not running.
Page 455 5) Turn OFF the inverter, and the following operations are automatically performed. The inverter measures the discharging time of the DC link bus capacitor and saves the result in function code H47 (Initial capacitance of DC link bus capacitor). The conditions under which the measurement has been conducted will be automatically collected and saved.

Page 462 6.3 Details of Function Codes In addition, during deceleration triggered by turning the run command OFF, anti-regenerative control increases the output frequency so that the inverter may not stop the load depending on the load state (huge moment of inertia, for example). To avoid that, H69 provides a choice of cancellation of anti-regenerative control to apply when three times the specified deceleration time is elapsed, thus decelerating the motor forcibly.

Page 698 Chapter 10 MAINTENANCE AND INSPECTION This chapter provides the instructions on how to perform daily and periodic inspections in order to avoid trouble and keep reliable operation of the inverter for a long time. Contents 10.1 Daily Inspection ............................10-1 10.2 Periodic Inspection............................
Page 700: Daily Inspection
10.1 Daily Inspection • Before proceeding to the maintenance/inspection jobs, turn OFF the power and wait at least ten minutes. Make sure that the LCD monitor is turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).

Page 702: List Of Periodic Replacement Parts
These parts are likely to deteriorate with age due to their constitution and properties, leading to the decreased performance or failure of the inverter. When the replacement is necessary, consult your Fuji Electric representative. Table 10.2 Replacement Parts Standard replacement intervals (See Note below.)
Page 703: Judgment On Service Life
10.3.1 Judgment on service life The inverter has the life prediction function for some parts which measures the discharging time or counts the voltage applied time, etc. The function allows you to monitor the current lifetime state on the LCD monitor and judge whether those parts are approaching the end of their service life. The life prediction function can also issue early warning signals if the life time alarm command LIFE is assigned to any of the digital output terminals.
Page 704 10.3 List of Periodic Replacement Parts The service life of the DC link bus capacitor can be judged by the "measurement of discharging time" or "ON-time counting." Measurement of discharging time of the DC link bus capacitor - The discharging time of the DC link bus capacitor depends largely on the inverter's internal load conditions, e.g.
Page 705: 2 ] Measuring The Capacitance Of The Dc Link Bus Capacitor Under Ordinary Operating Conditions
• Ensure that transistor output signals ([Y1] to [Y4]) and relay output signals ([Y5A/C] and [30A/B/C]) will not be turned ON. • Disable the RS-485 communications link. If negative logic is specified for the transistor output and relay output signals, they are considered ON when the inverter is not running.
Page 706: 3 ] Early Warning Of Lifetime Alarm
10.3 List of Periodic Replacement Parts Hereafter, each time the inverter is turned OFF, it automatically measures the discharging time of the DC link bus capacitor if the above conditions are met. Periodically check the relative capacitance of the DC link bus capacitor (%) with PRG > 3(INV Info) > 4(Maintenance) in Programming mode. The condition given above produces a rather large measurement error.
Page 707: Measurement Of Electrical Amounts In Main Circuit
10.4 Measurement of Electrical Amounts in Main Circuit Because the voltage and current of the power supply (input, primary circuit) of the inverter main circuit and those of the motor (output, secondary circuit) contain harmonic components, the readings may vary with the type of the meter. Use meters listed in Table 10.4 when measuring with meters designed for commercial frequencies.
Page 708: Insulation Test
A withstand voltage test may also damage the inverter if the test procedure is wrong. When the withstand voltage test is necessary, consult your Fuji Electric representative. (1) Megger test of main circuit 1) Use a 500 VDC Megger and shut off the main power supply without fail before measurement.

Page 735: Noise
Noise This section gives a summary of noises generated in inverters and their effects on devices subject to noise. [ 1 ] Inverter noise Figure A.1 shows an outline of the inverter configuration. The inverter converts AC to DC (rectification) in a converter unit, and converts DC to AC (inversion) with 3-phase variable voltage and variable frequency.
Page 736 App. A Advantageous Use of Inverters (Notes on electrical noise) [ 2 ] Types of noise Noise generated in an inverter is propagated through the main circuit wiring to the power supply and the motor so as to affect a wide range of applications from the power supply transformer to the motor.

Page 738 App. A Advantageous Use of Inverters (Notes on electrical noise) [ 2 ] Implementation of noise prevention measures There are two types of noise prevention measures--one for noise propagation routes and the other for noise receiving sides (that are affected by noise). The basic measures for lessening the effect of noise at the receiving side include: Separating the main circuit wiring from the control circuit wiring, avoiding noise effect.
Page 739 What follows is noise prevention measures for the inverter drive configuration. (1) Wiring and grounding As shown in Figure A.7, separate the main circuit wiring from control circuit wiring as far as possible regardless of being located inside or outside the system control panel containing an inverter. Use shielded wires and twisted shielded wires that will block out extraneous noises, and minimize the wiring distance.
Page 740 App. A Advantageous Use of Inverters (Notes on electrical noise) (3) Anti-noise devices To reduce the noise propagated through the electrical circuits and the noise radiated from the main circuit wiring to the air, a line filter and power supply transformer should be used (refer to Figure A.10).

Page 747: Regarding Existing Equipment
[ 2 ] Suppressing surge voltages There are two ways for suppressing the surge voltages, one is to reduce the voltage rise time and another is to reduce the voltage peak value. (1) Output reactor If wiring length is relatively short, the surge voltages can be suppressed by reducing the voltage rise time (dv/dt) with the installation of an AC reactor on the output side of the inverter.
