1Negative PID feedback from external terminal AVI (Pr.03-00)

2Negative PID feedback from PG card (Pr.10-15, skip direction)

3Negative PID feedback from PG card (Pr.10-15)

4Positive PID feedback from external terminal AVI (Pr.03-00)

5Positive PID feedback from PG card (Pr.10-15, skip direction)

6Positive PID feedback from PG card (Pr.10-15)

Negative feedback means: +target value – feedback. It is used for the detection value will be increased by increasing the output frequency.

Positive feedback means: -target value + feedback. It is used for the detection value will be decreased by increasing the output frequency.

This parameter determinates the gain of the feedback loop. If the gain is large, the response will be strong and immediate (if the gain is too large, vibration may occur). If the gain is small, the response will weak and slow.

This parameter determines the speed of response for the PID feedback loop. If the integral time is long, the response will be slow. If the integral time is short, the response will be quick. Be careful not to set(I) too small, since a rapid response may cause oscillation in the PID loop. If the integral time is set as 0.00, Pr.08-02 will be disabled.
