4.3.2 Initializing the parameters required to drive an IPM motor (Pr.998)
< IPM>
....Specifications differ according to the date assembled. Refer to page 346 to check the SERIAL number.
(1) IPM parameter initialization (Pr.998)

By performing IPM parameter initialization, initial settings required to drive an IPM motor can be set in parameters.

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.
Parameters referred to
Pr.60 Energy saving control selection Refer to page 174
Pr.72 PWM frequency selection Refer to page 181
Pr.190 or Pr.192 (Output terminal function selection) Refer to page 140
Pr. 261 Power failure stop selection Refer to page 168
Pr.653 Speed smoothing control Refer to page 182
Pr.800 Control method selection Refer to page 88

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, 12 (rotations per minute)" to "101, 112 (frequency)," or
from "101, 112" to "1, 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.
