NOTE
• 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 are initialized too. (Refer to
• To change back to the parameter settings required to drive an induction motor, perform Parameter clear or All parameter clear.
• Whenever the setting of Pr.998 PM parameter initialization is changed from "12, 14, 8009, or 9009" (setting/monitoring in
rotations per minute) to "112, 114, 8109, 9109" (setting/monitoring in frequencies), and vice versa, the motor parameters are
changed.
The purpose of this parameter is not to change the setting/monitoring unit. Use Pr.144 Speed setting switchover just to
change the unit between rotations per minute and frequencies. Using Pr.144 enables switching the unit between rotations per
minute and frequencies without initializing the setting of the motor parameters.
Example) Changing the Pr.144 setting between "6" and "106" switches the setting/monitoring unit between frequencies and
rotations per minute.
• For an inverter out of the capacity range of the IPM motor MM-EFS or MM-THE4, the settings "12, 14, 112, and 114" are
disabled. (Refer to
• PM parameter initialization (Pr.998) is used for change of parameter settings for use of a PM motor as the first motor. When
a PM motor is used as the second motor, the motor parameters for the second motor must be set individually.
