2 : PID SP Value
The drive inputs the PID control target value received from terminal PI.
3 : PG Feedback
Select V/f Control method to enable simple encoder feedback.
Use motor speed feedback for better speed control precision. The drive compares the frequency reference to the
motor speed feedback received from the encoder, and uses the ASR function to compensates for motor slip. You
cannot use input terminal RP used for the simple encoder to detect the direction of motor rotation. Use a different
method to detect motor rotation.
Use these methods to detect the direction of motor rotation.
• Use DI
Set DI H1-xx = 15 [FWD/REV Det]. When the configured terminal is activated, the motor operates in Reverse
run. When the terminal is deactivated, the motor operates in Forward run.
Use an encoder that outputs 2-tracks (phase A, B) to detect the direction of motor rotation.
• Use the frequency reference
When the you do not use the DI, the Forward/Reverse run command is the same as the direction of motor
rotation.

Enable Simple Closed Loop V/f Mode
1. Connect the encoder output pulse wiring to terminal PI.
2. Set A1-02 = 0 [Control Method = V/f Control].
3. Set H6-01 = 3.
4. Set H6-02 [PI Frequency Scale] to the speed feedback (pulse train input signal) frequency at the time when
the frequency reference is 100%.
Make sure that H6-04 [PI Function Bias] = 0% and H6-03 [PI Function Gain] = 100%.
5. Select the detection method for the direction of motor rotation.
When you use an MFDI, set H1-xx = 15.
6. Set C5 parameters related to ASR gain and integral time to adjust responsiveness.
Note:
• Set A1-02 = 0 and H6-01 = 3 to show C5 parameters.
• You cannot use Closed Loop V/f Control mode with the Motor Switch function.
