B.1 Current capacity of MSD Servo Drive DC-AC
The maximum permissible 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 system and the ambient temperature. If the conditions change, the maxi-
mum permissible current capacity of the servo drives also changes.
