Application Example of AC Reactor
Connected in input circuit
Application 1
When more than one Hybrid servo drive is connected to the same mains power and one of them is ON
during operation.
Problem: When applying power to one of the Hybrid servo drive, the charge current of the capacitors
may cause voltage dip. The Hybrid servo drive may be damaged when over current occurs
during operation.
