3.1.3 Wiring Methods
For servo drives from 100W to 1.5kW the input power can be either single or three-phase. For servo
drives 2kW and above only three-phase connections are available. But, 220V single-phase models are
available in 1.5kW and below only and 110V single-phase models are available in 400W and below only.
In the wiring diagram figures 3.3, 3.4 & 3.5:
Power ON : contact “a” (normally open)
Power OFF : contact “b” (normally closed)
MC : coil of electromagnetic contactor, self-holding power, contact of main circuit power
