1. Confirm whether FSSB is initialized normally (1902#1=1);
2. Confirm whether the motor code/parameters are correct (when there are different maximum speeds and different drive powers, be sure to check the parameters according to the standard parameter table. The latest information is available in our official account);
3. Cut off the power, pull out the drive control board and reinstall it reliably;
4. Appropriately adjust 4040, 4050 as shown in the figure (the first two are rotational, and the last two are directional);
The above can generally solve the problem of spindle rotation or orientation failure.
