A.1 Current carrying capacity of the 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, the design of the cooling and the ambient temperature. If the conditions
change, the maximum permissible current carrying capacity of the servo drives also
changes.
