A Appendix
A.1 Current capacity of servo drives
The maximum permissible servo drive output current and the peak current are
dependent on the mains voltage, the motor cable length, the power stage switching
frequency and the ambient temperature. If the conditions change, the maximum
permissible current capacity of the servo drives also changes.
