B.6.3 Applications for AC Reactor

Connected in input circuit

Application 1

Question

When more than one AC motor drive is

connected to the same power, one of them is

ON during operation.

Correct wiring

M1 reactor

When applying to one of the AC motor drive,

the charge current of capacity may cause

voltage ripple. The AC motor drive may

damage when over current occurs during

operation.
