Machine in Question:
Kiwa Excel Center 1200
Fanuc 10M controller
Spindle Servo Unit: A06B-6055-H106
Spindle Motor: A06B-1006-B100
machine is run on a phase converter
ratio between spindle motor and spindle is 2:1 (or close to it) making maximum spindle speed ~2900rpm
I'm receiving the "Excess Voltage in Servo" error upon decelerating my spindle. For the past couple weeks I've been working around this by programming in steps and dwell times when decreasing spindle speeds but I would really like to fix the problem in a more permanent way.
When a new spindle speed is commanded, it is probably reached in far less than a half second. The I'm not using this as a production machine where cycle times matter to that extent; can I increase the acceleration / deceleration ramp time in the controller?
As a side note, i'm looking for a spare spindle unit (not the motor) for parts and would like to change pulleys on the motor and spindle to achieve higher speeds. There was a 4000rpm and 6000rpm spindle as an option on my machine and I think the 4000rpm version had all the same parts except for the pulleys. Any sources would be greatly appreciated.
I ask about the spindle parts because I'm sure I would need to change parameters and'/or settings on the spindle servo unit to 'tell the controller' about the mechanical changes. Any info on this would also be greatly appreciated.
