The optimum gain is automatically set from
the torque command and speed during
2
motor operation.
Manual input of load (Pr. 880)
Set the proportional gain for speed control.
(Increasing the value improves trackability
1% 60% 0 to 1000% in response to a speed command change
and reduces speed variation with
disturbance.)
Second function of Pr. 820 (valid when RT
0 to 1000%
signal is on)
1% 9999
9999 No function
Set the integral time during speed control.
(Decrease the value to shorten the time
0.001s 0.333s 0 to 20s
taken for returning to the original speed if
speed variation with disturbance occurs.)
Second function of Pr. 821 (valid when the
0 to 20s
RT terminal is on)
0.001s 9999
9999 No function
Set the primary delay filter for the speed
0.001s 0.001s 0 to 0.1s
feedback.
Second function of Pr. 823 (valid when RT
0 to 0.1s
signal is on)
0.001s 9999
9999
No function
Set the proportional gain for the current
control of the q and d axes. (Increasing the
1% 100% 0 to 200% value improves trackability in response to a
current command change and reduces
current variation with disturbance.)
Second function of Pr. 824 (valid when the
0 to 200%
RT terminal is on)
1% 9999
9999 No function
Set the integral time for the current control
of the q and d axes. (Decreasing the value
0.1ms 5ms 0 to 500ms shortens the time taken to return to the
original torque if current variation with
disturbance occurs.)
Second function of Pr. 825 (valid when the
0 to 500ms
RT signal is on)
0.1ms 9999
9999 No function
Set the primary delay filter for the current
0.001s 0s 0 to 0.1s
feedback.
Second function of Pr. 827 (valid when the
0 to 0.1s
RT signal is on)
0.001s 9999
