IPM motor control, IPM parameter initialization
Pr.998 IPM parameter initialization
An IPM (interior permanent magnet) motor is a highly efficient motor compared to a general-purpose motor. Highly
efficient motor control and highly accurate motor speed control can be performed by using the inverter with an IPM
motor.
 For the motor model, dedicated IPM motor (MM-EFS model or MM-EF model) must be used.
 The motor capacity must be equivalent to the inverter capacity.
 Single-motor operation (one motor run by one inverter) must be performed.
 The overall wiring length with the motor must be within the specified value. (Refer to page 71)
Setting procedure of IPM motor control
This inverter is set for a general-purpose motor in the initial setting. Follow the following procedure to change the
setting for the IPM motor control.
IPM motor (MM-EFS) control setting from the operation panel (parameter setting mode)

POINT
 The parameters required to drive an IPM motor are automatically changed as a batch.
 To switch to the IPM motor control, initialize the parameter settings in the parameter setting mode or by setting Pr.998. If
parameter initialization is performed after setting other parameters, some of those parameters will be initialized too.
(Refer to the next page for the parameters initialized with this operation.)

REMARKS
 Performing IPM parameter initialization in the parameter setting mode of the operation panel automatically changes the Pr.998
IPM parameter initialization setting.
 To check the control method (general-purpose motor control/IPM motor control), simply press the setting dial while the monitor
screen is displayed. (Refer to page 21)
 The IPM parameter setting is displayed as "1, 12" in the parameter setting mode even if Pr.998 IPM parameter initialization =
"101, 112."
