Figure 2.2.1: Power Connections
Asynchronous and synchronous motors can be connected to the MICROMASTER
inverters either individually or in parallel.
Note:
If a synchronous motor is connected to the inverter, the motor current may be
two and a half to three times greater than that expected, so, the inverter must be de-
rated accordingly.
