or A3 auxiliary speed frequency reference input to terminal A2 will be used for the Inverter frequency refer- ence when the multi-speed reference 1 allocated to multi-function input terminal is ON. When using terminal A2 as the input terminal of auxiliary speed frequency reference, set H3-09 (Multi-func- tion analog input terminal A2 function selection) to 2 [Auxiliary speed reference frequency 1 (2nd speed ana- log)].
Page 204
Frequency Reference Setting Frequency Reference Using Pulse Train Signals When b1-01 is set to 4, the pulse train input to control circuit terminal RP is used as the frequency reference. Set H6-01 (Pulse Train Input Function Selection) to 0 (frequency reference), and then set the 100% reference pulse frequency to H6-02 (Pulse Train Input Scaling).
Using Multi-Step Speed Operation With Varispeed-F7 series Inverters, you can change the speed to a maximum of 17 steps, using 16 frequency references, and one jog frequency reference.

Stopping Methods Deceleration to Stop If the Stop Command is input (i.e., the Run Command is turned OFF) when b1-03 is set to 0, the motor decel- erates to a stop according to the deceleration time that has been set. (Factory setting: C1-02 (Deceleration Time 1)) If the output frequency when decelerating to a stop falls below b2-01, the DC injection brake will be applied using the DC current set in b2-02 only for the time set in b2-04.
Page 215
The following only applies to Inverters with SPEC: E or later. The operation after starting or stopping depends on the setting of b1-05 when flux vector control is selected (A1-02 = 3). Run Command OFF Frequency reference E1-09 via analog input Run Command turns OFF and zero-speed control starts when motor speed drops to b2-01.
Page 216
Stopping Methods Coast to Stop If the Stop Command is input (i.e., the Run Command is turned OFF) when b1-03 is set to 1, the Inverter out- put voltage is interrupted. The motor coasts to a stop at the deceleration rate that counterbalances damage to the machine and inertia including the load.
Coast to Stop with Timer If the Stop Command is input (i.e., the Run Command is turned OFF) when b1-03 is set to 3, the Inverter out- put is interrupted to coast the motor to a stop. After the Stop Command is input, Run Commands are ignored until the time T has elapsed.

Acceleration and Deceleration Characteristics Switching Acceleration and Deceleration Time Automatically Use this setting when you want to switch acceleration/deceleration time automatically using the set frequency. When the output frequency reaches the set value in C1-11, the Inverter switches the acceleration/deceleration time automatically as shown in the following diagram.
Page 223
Entering S-curve Characteristics in the Acceleration and Deceleration Time By performing acceleration and deceleration using an S-curve pattern, you can reduce shock when starting and stopping the machine. Using the Inverter, you can set an S-curve characteristic time for each of the following: Acceleration start time, deceleration start time, acceleration end time, and deceleration end time.
Acceleration and Deceleration Characteristics Accelerating and Decelerating Heavy Loads (Dwell Function) The dwell function stores the output frequency when starting or stopping heavy loads. By temporarily storing the output frequency, you can prevent the motor from stalling. When using the dwell function, you must select a deceleration stop.
Preventing the Motor from Stalling During Acceleration (Stall Prevention During Acceleration Function) The Stall Prevention During Acceleration function prevents the motor from stalling if a heavy load is placed on the motor, or sudden rapid acceleration is performed. If you set L3-01 to 1 (enabled) and the Inverter output current exceeds the -15% level of the set value in L3- 02, the acceleration rate will begin to slow down.

Preventing Overvoltage During Deceleration (Stall Prevention During Deceleration Function) The Stall Prevention During Deceleration function makes the rate of deceleration more gentle to suppress increases in DC bus voltage when the DC bus voltage exceeds the set value during motor deceleration. This function automatically lengthens the deceleration time with respect to the bus voltage, even if the decel- eration time has been set to a considerably small value.

Operation Avoiding Resonance (Jump Frequency Function) The jump frequency function operates the motor while avoiding resonance caused by characteristic frequen- cies in the machinery. This function is effective in creating a frequency reference dead band. During constant-speed operation, operation within the jump frequency range is prohibited. Smooth operation still used during acceleration and deceleration, i.e., jumps are not performed.

Improved Operating Efficiency Improved Operating Efficiency This section explains functions for improving motor operating efficiency. Reducing Motor Speed Fluctuation (Slip Compensation Function) When the load is large, the amount of motor slip also grows large and the motor speed decreases. The slip compensation function controls the motor at a constant speed, regardless of changes in load.
Page 239
Adjusting Slip Compensation Gain You can switch the C3-01 constant settings as shown below by changing the control method. V/f control: 0.0 • Open-loop vector control: 1.0 • • Flux vector control: 1.0 Set C3-01 to 1.0 to compensate the rated slip set using the rated torque output status. Adjust the slip compensation gain using the following procedure.

Preventing Motor Stalling During Operation Stall prevention during operation prevents the motor from stalling by automatically lowering the Inverter's output frequency when a transient overload occurs while the motor is operating at a constant speed. Stall prevention during operation is enabled only during V/f control. If the Inverter output current continues to exceed the setting in constant L3-06 for 100 ms or longer, the motor speed is reduced.

Inverter Protection Reducing Inverter Overheating Pre-Alarm Warning Levels The Inverter detects the temperature of the cooling fins using the thermistor, and protects the Inverter from overheating. You can receive Inverter overheating pre-alarms in units of 10 ° The following overheating pre-alarm warnings are available: Stopping the Inverter as error protection, and continuing operation, with the alarm OH (Radiation fins overheating) on the Digital Operator flashing.
Input Terminal Functions This section explains input terminal functions, which set operating methods by switching functions for the multi-function contact input terminals (S3 to S8). Temporarily Switching Operation between Digital Operator and Control Circuit Terminals You can switch the Inverter Run Command inputs and frequency reference inputs between local (i.e., Digital Operator) and remote (input method using b1-01 and b1-02).
Input Terminal Functions Blocking Inverter Outputs (Baseblock Commands) Set 8 or 9 (Baseblock command NO/NC) in one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selection) to perform baseblock commands using the terminal's ON/OFF operation, and prohibit Inverter output using the baseblock commands.
Stopping Acceleration and Deceleration (Acceleration/Deceleration Ramp Hold) The acceleration/deceleration ramp hold function stops acceleration and deceleration, stores the output fre- quency at that point in time, and then continues operation. Set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selection) to A (acceleration/deceleration ramp hold) to stop acceleration and deceleration when the terminal is turned ON and to store the output frequency at that point in time.
Input Terminal Functions Application Precautions When d4-01 is set to 1, the output frequency on hold is stored even after the power supply is turned OFF. If • performing operations using this frequency after the Inverter has also been turned OFF, input the Run Command with the Acceleration/Deceleration Ramp Hold turned ON.
Page 277
Application Precautions Frequency outputs using UP/DOWN commands are limited by the frequency reference upper and lower • limits set in constants d2-01 to d2-03. Here, frequency references from analog frequency reference termi- nal A1 becomes the frequency reference lower limit. If using a combination of the frequency reference from terminal A1 and the frequency reference lower limit set in either constant d2-02 or d2-03, the larger lower limit will become the frequency reference lower limit.

To use this function, set One of the constants H1-01 to H1-06 (multi-function contact terminal inputs S3 to S8 function selection) to 1C (Trim Control Increase command) and 1D (Trim Control Decrease command).
Input Terminal Functions Hold Analog Frequency Using User-set Timing When one of H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selection) is set to 1E (sample/hold analog frequency command), the analog frequency reference will be held from 100 ms after the terminal is turned ON, and operation will continue thereafter at that frequency.
Setting Precautions To switch command inputs between the Communications Option Board and the control circuit terminals, set the following constants. Set b1-01 (Reference Selection) to 1 (Control circuit terminal [analog input]) • Set b1-02 (Operation Method Selection to 1 (Control circuit terminal (sequence inputs]) •...

Individual Functions Using the Timer Function Multi-function contact input terminals S3 to S8 can be designated as timer function input terminals, and multi- function output terminals M1-M2, P1-PC, and P2-PC can be designated as timer function output terminals. By setting the delay time, you can erase chattering from the sensors and switches. Set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8) to 18 (timer func- •...
Using PID Control PID control is a method of making the feedback value (detection value) match the set target value. By combin- ing proportional control (P), integral control (I), and derivative control (D), you can even control targets (machinery) with play time. The characteristics of the PID control operations are given below.

PID Target Value Input Methods Select the PID control target value input method according to the setting in b1-01 (Reference Selection). Normally, the frequency reference selected in b1-01 is the PID target value, but you can also set the PID target value as shown in the following table.

Individual Functions PID Fine Adjustment Methods This section explains the fine adjustment of PID after setting the PID control constants. Suppressing Overshoot If overshoot occurs, reduce derivative time (D), and increase integral time (I). Response Before adjustment After adjustment Time Set a Rapidly Stabilizing Control Condition To rapidly stabilize the control even if overshoot occurs, reduce integral time (I), and lengthen derivative time (D).
Page 309
Suppressing Short Cycle Vibration If vibration occurs when the vibration cycle is short, and the cycle is almost identical to the derivative time (D) set value, the differential operation is too strong. Shorten the derivative time (D) to suppress the vibration. If vibration continues even when the derivative time (D) is set to 0.00 (D control disabled), reduce the propor- tional gain (P), or increase the PID primary delay time constant.

PID Feedback Loss Detection When performing PID control, be sure to use the PID feedback loss detection function. If PID feedback is lost, the Inverter output frequency may accelerate to the maximum output frequency. When setting b5-12 to 1 and the status of the PID feedback value detection level in b5-13 is insufficient and continues for the time set in b5-14, an FbL (PID feedback reference lost) alarm will be displayed on the Digi- tal Operator and Inverter operation will continue.
Individual Functions Energy-saving To perform energy saving, set b8-01 (Energy Saving Mode Selection) to 1. Energy-saving control can be per- formed using both V/f control and vector control. The constants to be adjusted are different for each. In V/f control, adjust b8-04 to b8-06, and in vector control, adjust b8-02 and b8-03. Related Constants Control Methods Change...

Individual Functions compensation value is output. In this way, the output from the speed limiter is used to maintain the motor speed between 0 and the speed limit. When the sum of the torque reference and the torque compensation out- put by the speed limiter is the same as the actual load, the motor will stop accelerating and run at a constant speed.
Page 329
Speed/Torque Control Switching Function It is possible to switch between speed control and torque control when one of the multi-function inputs (H1-01 to H1-06) is set to 71 (Speed/Torque Control Change). Speed control is performed when the input is OFF and torque control is performed when the input is ON.
Individual Functions Speed Control (ASR) Structure Speed control (ASR) during flux vector control adjusts the torque reference so that the deviation between the speed reference and the estimated speed (PG feedback) is 0. Speed control (ASR) during V/f control with a PG adjusts the output frequency so that the deviation between the speed reference and the estimated speed (PG feedback) is 0.

Individual Functions Speed Control (ASR) Gain Adjustment for Flux Vector Control (SPEC: E or Later Only) Use the following procedure to adjust C5-01 and C5-03 with the mechanical system and actual load con- nected. At zero-speed, increase C5-01 (ASR P Gain 1) until there is no oscillation. At zero-speed, decrease C5-02 (ASR I Time 1) until there is no oscillation.
Page 333
Adjusting ASR Proportional Gain 1 (C5-01) This gain setting adjusts the responsiveness of the speed control (ASR). The responsiveness is increased when this setting is increased. Usually this setting is higher for larger loads. Oscillation will occur if this setting is increased too much.
Page 334
Individual Functions Different Gain Settings for Low-speed and High-speed Switch between low-speed and high-speed gain when oscillation occurs because of resonance with the mechanical system at low speed or high speed. The proportional gain P and integral time I can be switched according to the motor speed, as shown below.
Page 335
Gain Adjustment for Speed Control during V/f Control with PG When using V/f control with PG, set the proportional gain (P) and the integral time (I) at E1-09 (minimum out- put frequency) and E1-04 (maximum output frequency). Speed Control Gain Integral Time Adjustment for V/f Control with PG shows how the proportional gain and integral time change in linear fashion based on the speed.
Individual Functions Increasing the Speed Reference Response (Feed Forward Control) (SPEC: E or Later Only) Use feed forward control to increase the responsiveness to speed references. This function is effective for machines for which the ASR gain cannot be increased to a large value because doing so would result in vibra- tions.

Stall Prevention during Deceleration If connecting a braking resistor to discharge regenerative energy, be sure to set Stall prevention selection dur- ing decel (L3-04) to 0 (Disabled). If Stall prevention selection during decel (L3-04) is set to 1, 2, or 3 , the motor may not stop within the speci- fied decelerating time.
Using Inverters for Elevating Machines I/O Open-phase Protection and Overtorque Detection To prevent the machine from falling when the motor is open-phase or a similar situation, enable L8-05 and L8- 07 (Input and output open-phase protection selection) and L6-01 to L6-06 (Overtorque detection) (factory set- ting is Disabled).
Control-related Adjustments The Varispeed F7 is designed to provide sufficient performance for elevating machines. However, if problems related to controllability should occur, such as vibration or slipping, adjust the following constants in accor- dance with the control method. Only constants that frequently require adjustment are listed in this table.

4. Use the ASR constants (C5-01 to C5-05) in their factory settings when using V/f control with PG (A1-02 = 1). Vibration may occur if these constants are changed greatly from their factory settings. 5. The torque and speed response of high-resistance (high-slip) motors are insufficient. Use appropriate adjustments to improve them. On the contrary, low-resistance (low-slip) motors are easily subject to hunting and vibration.

Troubleshooting Due to constant setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropriate measures. If the contents of the fault are displayed, refer to Protective and Diagnostic Functions.
Troubleshooting If the Motor Does Not Operate Use the following information if the motor does not operate. The motor does not operate when the RUN Key on the Digital Operator is pressed. The following causes are possible. If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the Menu Key to make the DRIVE indicator flash, and enter the drive mode by pressing the DATA/ENTER Key.
Page 392
The operation method selection is wrong. If constant b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an exter- nal operation signal is input. Set b1-02 to 1 (control circuit terminal) and try again. Similarly, the motor will also not operate if the LOCAL/REMOTE Key has been pressed to switch to Digital Operator operation.
Troubleshooting If the Direction of the Motor Rotation is Reversed If the motor operates in the wrong direction, the motor output wiring is faulty. When the Inverter T1(U), T2(V), and T3(W) are properly connected to the motor T1(U), T2(V), and T3(W), the motor operates in a for- ward direction when a Forward Run Command is executed.
or A3 A signal is being input to the frequency reference terminal A2 When 0 (frequency reference) is set for constant H3-09 (Multi-function Analog Input Terminal A2 Function or H3-05 (Multi-function Analog Input Terminal A3 Function Selection) Selection) , a frequency correspond- or A3 ing to the terminal A2 input voltage (current) is added to the frequency reference.
Troubleshooting The torque limit has been reached. When a torque limit has been set in constants L7-01 to L7-04, no torque will be output beyond that limit. This can cause the deceleration time to be too long. Check to be sure that the value set for the torque limit is suit- able.
Autotuning has not been performed for vector control Vector control will not perform if autotuning has not been performed. Perform autotuning, or set the motor constants through calculations. Alternatively, change the Control Method Selection (A1-02) to V/f control (0 or 1). If There is Noise When the Inverter is Started or From an AM Radio If noise is generated by Inverter switching, implement the following countermeasures: Change the Inverter's Carrier Frequency Selection (C6-02) to lower the carrier frequency.
Troubleshooting Oscillation and hunting are occurring with open-loop vector control. The gain adjustment may be insufficient. Reset the gain to a more effective level by adjusting constants C4-02 (torque compensation time constant), C2-01 (S-curve Characteristic Time at Acceleration Start), and C3-02 (Slip Compensation Primary Delay Time) in order.
If the Motor Rotates Even When Inverter Output is Stopped If the motor rotates even when the Inverter output is stopped, the DC injection braking is insufficient. If the motor continues operating at low speed, without completely stopping, and after a deceleration stop has been executed, it means that the DC injection braking is not decelerating enough.
The free warranty period of the Inverter is as follows: Free warranty Period: This product is warranted for twelve months after being delivered to Yaskawa’s cus- tomer or if applicable eighteen months from the date of shipment from Yaskawa’s factory whichever comes first.

Varispeed F7 Control Methods Details of the Varispeed F7-Series Inverter control methods and their features are provided in this section. Control Methods and Features Varispeed F7-Series Inverters support the following four control methods, allowing the selection of a control method to suit the required purpose. Table 10.1 provides an overview of the control methods and their fea- tures.

Application Function Precautions Observe the following precautions when using the application functions. Perform rotational autotuning during trial operation whenever it is possible to separate the motor and • machine. To achieve the characteristics of vector control described in Table 10.1, the control must be adjusted within a range that the machine will not vibrate after rotational autotuning has been performed.

Applications with repetitive loads (cranes, elevators, presses, washing machines, etc.) using Inverters require derating for the repetitive load [reducing carrier frequency and current (changing accel/decel timing, increas- ing the frame size of the Inverter)]. Contact your Yaskawa representative for details. Initial Torque The startup and acceleration characteristics of the motor are restricted by the overload current ratings of the Inverter that is driving the motor.
Inverter Application Precautions Options Terminals B1, B2, 3 are for connecting only the options specifically provided by Yaskawa. Never connect any other devices to these terminals. Installation Observe the following precautions when installing an Inverter. Installation in Enclosures Either install the Inverter in a clean location not subject to oil mist, air-bourne matter, dust, and other contam- inants, or install the Inverter in a completely enclosed panel.
Page 430
Wiring Check The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W. Check wring for any mistakes before supplying power. Check all wiring and sequences carefully. Magnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line. Doing so can cause the Inverter to malfunction.
Cooling effects diminish in the low-speed range, resulting in an increase in the motor temperature. Therefore, the motor torque should be reduced in the low-speed range whenever using a motor not made by Yaskawa. If 100% torque is required continuously at low speed, consider using a special Inverter or vector motor.
Noise Noise varies with the carrier frequency. At high carrier frequencies, the noise is almost the same when the motor is operated with a commercial power supply. Motor noise, however, becomes louder when the motor is operated at a speed higher than the rated speed (60 Hz). Using the Inverter for Special Motors Observe the following precautions when using a special motor.
Conformance to UL Standard Conformance to UL Standard To comply with UL standard, follow the appropriate installation instructions. Installation Site Install the Inverter in a pollution degree 2 environment or equivalent. Specification of Closed-Loop Connector The closed-loop connectors must be installed on conductors before installing to terminal blocks. Use JST or equivalent closed-loop connectors shown below.
