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 [Pulse Train Input Scaling] to the speed feedback (pulse train input signal) frequency at the time
when the frequency reference is 100%.
Confirm that H6-04 [Pulse Train Input Bias] is 0% and H6-03 [Pulse Train Input Gain] is 100%.
5. Select the detection method for the direction of motor rotation.
Set H1-xx to 7E when using an MFDI.
6. Set C5 parameters related to ASR gain and integral time to adjust responsiveness.
Note:
• C5 parameters appear when A1-02 = 0 and H6-01 = 3.
• The simple Closed Loop V/f Control mode cannot be used in conjunction 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 [PulseTrain InTerm RP Func Select] is input at 100%.
V/f CL-V/f OLV CLV
Sets the gain used when the item configured with H6-01 [PulseTrain
InTerm RP Func Select] is input to terminal RP.
V/f CL-V/f OLV CLV
Sets the bias used when the item configured with H6-01 [PulseTrain InTerm
RP Func Select] is input to terminal RP. Sets a value at the time when the
pulse train is 0 Hz.
