Asynchronous and synchronous motors can be connected to the
MICROMASTER Vector 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. Also, the inverter cannot be used in vector mode when connected to a
synchronous motor (P077= 0 or 2).
