A.1 Current carrying capacity,
MSD Servo Drives DC-AC
The maximum permissible DC-AC Servo Drive output current and the peak current are
dependent on the DC supply 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 DC-AC Servo Drives
also changes.
