For the software version V5.18, the production time is before the date of 2019.6.13, and the GR series servo drive unit (including GR2075, GR2100, GR2148, GR3000 series) with synchronous servo motor, the motor current appears when the motor is called with the default parameters. Whistling, if the motor current is large, please follow the steps below:

1、Disconnect the system

2、PA0=7777；With synchronous machine PA2=0

3、PA224=10

4、PA230=33

5、PA231=33

6、PA238=33

7、PA254=14

8、PA252= Corresponding drive model value (see Table 1 below)

note:

Case 1: If PA252 is not equal to the corresponding drive model value, modify the setting to the corresponding drive model value and press the enter key to confirm the write;

Case 2: If PA252 is equal to the corresponding drive model value, first change to another drive model value, press Enter to write, then modify to the corresponding drive model value, and press Enter again to write.

For example: GR2100 original PA252 value is the corresponding drive model value 1115, should first put PA252=1114, and press the confirm button; finally put PA252=1115, and press the confirm button again.

9、If it is equipped with an asynchronous spindle (PA2=1), put PA253=10; if it is equipped with a synchronous machine (PA2=0), skip this step.

10、Finally, you must execute EE-SET to save the above modified parameter values; then perform EE-BA backup save.
