1.3 Initializing the parameters required to drive an IPM motor (Pr.998)
(1) IPM parameter initialization (Pr. 998)
· When Pr. 998 = "1 or 12," the monitor is displayed and the frequency is set using the motor rotations per
minute.
To use frequency to display or set, set Pr. 998 = "101 or 112."
·Set Pr. 998 = "0" to change the parameter settings from the settings required to drive an IPM motor to the
settings required to drive a general-purpose motor.
· By performing IPM parameter initialization, IPM motor control is selected and the parameters, which
are required to drive an IPM motor, are changed. Initial settings and setting ranges of the parameters
are adjusted automatically to drive an IPM motor.
· Initialization is performed by setting Pr. 998 IPM parameter initialization or by choosing the mode on the
operation panel.

REMARKS
· Make sure to set Pr. 998 before setting other parameters. If the Pr.998 setting is changed after setting other
parameters, some of those parameters will be initialized too. (Refer to "(2) IPM parameter initialization list" for the
parameters that are initialized.)
· To change back to the parameter settings required to drive a general-purpose motor, perform parameter clear or all
parameter clear.
· If the setting of Pr. 998 IPM parameter initialization is changed from "1 or 12 (rotations per minute)" to "101 or 112
(frequency)," or from "101 or 102" to "1 or 12," all the target parameters are initialized.
The purpose of Pr. 998 is not to change the display units. Use Pr. 144 Speed setting switchover to change the display
units between rotations per minute and frequency. Pr. 144 enables switching of display units between rotations per
minute and frequency without initializing the parameter settings.
Example) Changing the Pr. 144 setting between "6" and "106" switches the display units between frequency and
rotations per minute.
