Spindle Motor No Brake

 It is an old lathe machine retrofitting, the spindle motor slips every time without brake working, other functions are fine.



1-      Check if the related parameters for the spindle brake are set properly or not on the CNC controller?

2-      The spindle brake resistant cable is connected well, or is there any open circuit for the brake resistance?

3-      Any wrong parameters on the frequency inverter?

4-      Is the frequency inverter broken?


In this case we checked out the brake mode parameter of the frequency inverter was set wrong, change the frequent slipping mode to the outer resistance brake mode, the spindle motor brake can be used.
