Description
1: Slow response
↓
15: Fast response
No tuning
With load estimation
(only under vector control)
The optimum gain is automatically
set from the torque command and
speed during motor operation.
Manual input of load (Pr. 880)
Set the proportional gain for speed
control.
(Increasing the value improves
trackability in response to a speed
command change and reduces
speed variation with disturbance.)
Second function of Pr. 820 (valid
when RT signal is on)
No function
Set the integral time during speed
control.
(Decrease the value to shorten the
time taken for returning to the
original speed if speed variation
with disturbance occurs.)
Second function of Pr. 821 (valid
when the RT terminal is on)
No function
Set the primary delay filter for the
speed feedback.
Second function of Pr. 823 (valid
when RT signal is on)
No function
