Object Details
Note
A change of the Motor Type value will cause an inverter and DeviceNet option
board reset. This is equivalent to setting inverter parameters b171 (Inverter
mode selection) and b180 (Parameter initialisation trigger).

Motor Type
Depends on the motor control mode which is
selected for the inverter. The motor control mode
can be read by inverter parameter d060.
Get values:
3: PM synchronous motor (d060 = 3)
7: Squirrel cage induction motor (d060 != 3)
Set values:
3: in case inverter control mode is not in this mode,
the inverter will be set to PM synchronous mode
(d060 = 3).
7: in case inverter control mode is PM synchronous
mode (d060 = 3), the inverter will be set to ND
mode (d060 = 1).
