Figure 1.28 Speed Control with ASR in V/f with Simple Speed Feedback
To activate V/f Control with PG 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 the signal used for detecting the direction. If a digital input is used set H1- = 7F.
4. Use the ASR gain and integral time parameters described below for adjusting the ASR
responsiveness.
Note: 1. C5 parameters will appear only when using V/f Control (A1-02 = 0) and when the pulse input RP
function is set for PG feedback in V/f Control (H6-01 = 3).
2. V/f Control with PG feedback can be used for motor 1 only.
ASR Tuning Parameters
ASR provides two sets of gain and integral time. Set 1 is active at the maximum output
frequency, set 2 is active at the minimum output frequency. The settings are changed linearly
depending on the output frequency as shown in the figure below.
