Speed Control Response
Sets the level of speed control responsiveness. Usually it is not necessary to change this setting.
0
(0, 1)
If a high level of speed control responsiveness is necessary, set C5-29 = 1,then adjust the speed control (ASR)
parameter.
0 : Standard
1 : High Performance 1
■ C5-32: Motor 2 Integral Oper at Acc/Dec
No.
(Hex.)
Name Description
Default
(Range)
C5-32
(0361)
Motor 2 Integral Oper at
Acc/Dec
Sets ASR integral operation during acceleration and deceleration for motor 2.
0
(0, 1)
When it is necessary for the motor speed to be as near the frequency reference as possible during acceleration or
deceleration, set this parameter to 1.
Note:
If you enable integral control, overshoot or undershoot can occur when acceleration or deceleration complete. If there are problems with
overshooting and undershooting, set this parameter to 0.
0 : Disabled
Integral operation is not enabled during acceleration or deceleration. Integral operation is always enabled during
constant speed.
1 : Enabled
Integral operation is always enabled.
