Speed detection
filter function
823
Speed detection
filter 1
0.001s 0.001s 0 to 0.1s Set the primary delay filter for the speed feedback.
833
Speed detection
filter 2
0.001s 9999
0 to 0.1s
Second function of Pr. 823 (valid when RT signal is
on)
9999 No function
Current loop
proportional gain setting
824
Torque control P gain 1
1% 100% 0 to 200%
Set the proportional gain for the current control of the
q and d axes. (Increasing the value improves
trackability in response to a current command
change and reduces current variation with
disturbance.)
834
Torque control P gain 2
1% 9999
0 to 200%
Second function of Pr. 824 (valid when the RT
terminal is on)
9999 No function
Current control
integral time setting
825
Torque control integral time
1
0.1ms 5ms 0 to 500ms
Set the integral time for the current control of the q
and d axes. (Decreasing the value shortens the time
taken to return to the original torque if current
variation with disturbance occurs.)
835
Torque control integral time
2
0.1ms 9999
0 to 500ms
Second function of Pr. 825 (valid when the RT signal
is on)
9999 No function

Torque detection
filter function
827
Torque detection filter 1
0.001s 0s 0 to 0.1s Set the primary delay filter for the current feedback.
837
Torque detection filter 2
0.001s 9999
0 to 0.1s
Second function of Pr. 827 (valid when the RT signal
is on)
9999 No function
Speed feed forward control,
model adaptive speed control
828
Model speed control gain
1% 60% 0 to 1000% Set the gain for model speed controller.
877
Speed feed forward control/
model adaptive speed
control selection
10
0 Normal speed control is exercised
1 Speed feed forward control is exercised.
2 Model adaptive speed control is enabled.
878
Speed feed forward filter
0.01s 0s 0 to 1s
Set the primary delay filter for the speed feed forward
result calculated using the speed command and load
inertia ratio.
879
Speed feed forward torque
limit
0.1% 150% 0 to 400%
Limits the maximum value of the speed feed forward
torque.
880
Load inertia ratio
0.1 7
0 to 200
times
Set the load inertia ratio.
Inertia ratio found by easy gain turning.
881
Speed feed forward gain
1% 0% 0 to 1000% Set the feed forward calculation result as a gain.
