Enable Simple Closed Loop V/f Mode
1. Connect the encoder output pulse wiring to terminal RP.
2. Set A1-02 = 0 [Control Method Selection = V/f Control].
3. Set H6-01 = 3.
4. Set H6-02 [Terminal RP Frequency Scaling] to the speed feedback (pulse train input signal) frequency at the time
when the frequency reference is 100%.
Make sure that H6-04 [Terminal RP Function Bias] = 0% and H6-03 [Terminal RP Function Gain] = 100%.
5. Select the detection method for the direction of motor rotation.
When you use an MFDI, set H1-xx = 7E.
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 Simple Closed Loop V/f Mode with the Motor Switch function.

V/f CL-V/f OLV CLV
Sets the frequency of the pulse train input signal used when the item selected with H6-01 [Terminal
RP Pulse Train Function] is input at 100%.
V/f CL-V/f OLV CLV
Sets the gain used when the function in H6-01 [Terminal RP Pulse Train Function] is input to
terminal RP.
V/f CL-V/f OLV CLV
Sets the bias used when the function in H6-01 [Terminal RP Pulse Train Function] is input to
terminal RP. Sets a value at the time when the pulse train is 0 Hz.
