6.11.2 Nominal speed value monitoring
With the CC 61xx, nominal speed value monitoring is active as a rule, and
applies to the following values:
For axes:
The maximum feed rate is 15% greater than the maximum motor speed
(N-MAX) multiplied by MP1054.
For spindle(s):
The maximum spindle speed is 15% greater than the maximum motor
speed (N-MAX) multiplied by the gear transmission ratio.
If monitoring responds, the error message 88C0 Max. nominal motor speed
%s exceeded is output and an emergency stop reaction is initiated.
When using an EcoDyn motor, the error is triggered when the maximum
permissible voltage is exceeded.
