Soft-Start Operation - Aerotech DR300 Operation & Technical Manual

Soft-Start
4.2.
Soft-start operation is an automatic function that limits inrush current to approximately 10
amps for 100/115 VAC operation and 20 amps for 200/230 VAC operation. Inrush
current limiting is only activated during initial power-up or when AC power interruptions
last longer than .3 seconds. Short Power interruptions (less than about .3 seconds) will not
initiate a soft-start activation. This prevents the possibility of soft-start induced nuisance
trips during normal operation.
