Factory Setting
Parameter 41 allows one of three motor types to be selected for drive
control:
•
Induction by setting Parameter 41 to 0.
•
Synchronous reluctance by setting Parameter 41 to 1.
•
Synchronous Permanent Magnet by setting Parameter 41 to 2.
The value of Parameter 41 directly effects the programming of drive
Parameters 10 and 42.
When Parameter 41 is set to 2 (Synchronous Permanent Magnet Motor),
Parameter 10 must not be set to 1 (DC Brake-to-Stop). This type of braking
will reduce the field strength of the permanent magnets in the motor.
When Parameter 41 is set to a value of either 1 (Synchronous Reluctance),
or 2 (Synchronous Permanent Magnet), Parameter 42 must be set to 0 (no
slip compensation). Synchronous motors run without slip, and slip
compensation will not allow the motor to run at synchronous speed.
If the value of Parameters 10, 41 and 42 are not compatible, the drive will
detect it and Fault Code F11 (Operator Error), will appear when an attempt
is made to start the drive.
The type of motor selected restricts other parameters. The following
parameter settings must be used when selecting Parameter 41 Motor Type.
•
Induction Motor — Parameter 41 = 0
•
Synchronous Reluctance Motor — Parameter 41 = 1
Parameter 42 = 0
•
Synchronous Permanent Magnet Motor — Parameter 41 = 2
Parameter 42 = 0
Parameter 10 = 0 or 2
