During the adjustment, ensure that there are no persons or other irrelevant devices in the movable range
of the mechanical moving parts, and that reliable emergency shutdown measures are in place.
Automatic setting
1.
Set Byte0 of the parameter [Current Loop Control Setting] (0x21E3) to 0x00(Automatical setting mode). Restart the servo
drive to make the parameter changes take effect.
2.
Test the system with the default value of [Current Control Gain Auto Setting Factor] (0x21E4), use the data tracing function
of the debugging software to trace the response of the system, and then adjust the value of the parameter [Current control
Gain Auto Setting Factor] according to the specific conditions.
3.
When it is necessary to improve the response performance of the system, increase the value of [Current Control Gain Auto
Setting Factor], but if the automatic setting coefficient is too high, the current loop can oscillate.
4.
When it is necessary to suppress the current loop oscillation, the value of [Current Control Gain Auto Setting Factor] can be
reduced, but the system response will also be slowed down accordingly.
Manual setting
1.
Set Byte0 of the parameter [Current Loop Control Setting] (0x21E3) to 0x01 (Manual setting mode), restart the servo drive
to make the parameter changes take effect.
2.
Use the data tracing function of the debugging software to trace the response of the system, and then adjust relevant
parameters according to the actual needs. Each parameter is described below.
[Current Loop Proportional Gain] is used to determine the responsiveness of the current loop. The larger the value,
the better the response performance. However, if the value is too high, it may cause current loop oscillation and
noises.
The smaller the setting value of the [Current Loop Integration Time Constant], the stronger the integration effect and
the better the current loop response performance. However, do not set the value too small, otherwise it may cause
current loop oscillation and noises; increasing the current loop integration time can reduce the response overshoot,
but over large current loop integration time might slow down the current loop response.
After the current loop parameters are configured initially, they usually do not need to be adjusted.
