Figure 5.86 Speed Control with ASR in V/f with Simple Speed Feedback
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 train input scaling). Make sure the pulse input bias (H6-04)
is 0% and the gain (H6-03) is 100%.
3. Decide the signal used for detecting the direction. If a digital input is used, set H1- = 7E.
4. Use the ASR gain and integral time parameters described in C5: Automatic Speed Regulator (ASR) on
page 222 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, note that the V/f Control with simple PG feedback can be used for motor 1 only.
■ H6-02: Pulse Train Input Scaling
This parameter sets the pulse signal frequency that is equal to 100% of the input value selected in parameter H6-01.
■
H6-03: Pulse Train Input Gain
Sets the level of the input value selected in H6-01 when a pulse train signal with the frequency set in H6-02 is input to
terminal RP.
■
H6-04: Pulse Train Input Bias
Sets the level of the input value selected in H6-01 when no signal (0 Hz) is input to terminal RP.
■
H6-05: Pulse Train Input Filter Time
Sets the pulse train input filter time constant in seconds.
