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.
Figure 12.111 shows speed control in Simple Closed Loop V/f Mode.

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.
