Parameter
Description
Sets the gain of the speed regulator (ASR_KP), which determines the responsiveness of the speed
control loop.
The larger the ASR_KP value setting, the higher the speed loop response frequency and the better the
followability for speed commands. By increasing the setting value of the speed loop gain, the response
characteristics of the servo system can be improved. However, when the ASR_KP setting is too large,
it is easy to cause vibration.

Parameter
Description
Sets the integration time of the speed regulator (ASR_Ki), which determines the responsiveness of the
speed control loop.
The smaller the ASR_Ki value setting, the higher the speed loop response frequency and the better the
follow-through for speed commands. By reducing the setting value of the velocity loop integration time,
the response characteristics of the servo system can be improved. However, when the ASR_Ki setting
is too small, vibration is easily caused.

Parameter
Description
Sets the gain of the position regulator (APR_KP), which determines the responsiveness of the position
control system.
The larger the APR_KP value, the higher the position response frequency, the better the followability for
position commands, the smaller the amount of position deviation, and the shorter the positioning
adjustment time. However, when the APR_KP value is set too large, it is easy to cause vibration.
