1.7 H: Terminal Functions
Enabling V/f Control with Simple Speed Feedback:
1.
Set the drive to V/f Control (A1-02 = 0).
2.
Connect the motor speed pulse signal to the pulse input RP, set H6-01 = 3, and set the pulse signal frequency that
is equal to the maximum speed to H6-02 (pulse input scaling). Make sure the pulse input bias (H6-04) is 0% and the
gain (H6-03) is 100%.
3.
Decide on the signal used for detecting the direction. Set H1-oo = 7E if using a digital input.
4.
Use the ASR gain and integral time parameters described in
for adjusting the responsiveness.
Note: 1. C5 parameters will appear when using V/f Control (A1-02 = 0) and when the pulse input RP function is set for simple PG feedback in
V/f Control (H6-01 = 3).
2. If running two motors from the same drive, V/f Control with simple PG feedback can be used for motor 1 only.
n H6-02: Pulse Train Input Scaling
Sets the pulse signal frequency that is equal to 100% of the input value selected in parameter H6-01.
No.
