 Motor parameter initialization for PM motor control (Pr.998)
• Use PM parameter initialization to set the parameters required for driving an IPM motor MM-EFS or MM-THE4.
• The offline auto tuning enables the operation with an IPM motor other than the MM-EFS or MM-THE4 and with SPM
motors.
• Two methods of the motor parameter initialization are available for the use of MM-EFS or MM-THE4 motor; using Pr.998
PM parameter initialization, and using IPM initialization (

*1 The setting is available for the standard structure model or the separated converter type.
• To use a motor capacity that is one rank lower than the inverter capacity, set Pr.80 Motor capacity before performing PM
parameter initialization.
• When "12, 14, 8009, or 9009" is set in Pr.998, the motor speed which was set/monitored in frequencies is set/monitored
in motor rotations per minute. To set/monitor in frequencies, set "112, 114, 8109, or 9109" in Pr.998.
• To change the setting of motor parameters for PM motor control to the setting required to drive an induction motor, set "0"
in Pr.998.
• When using an IPM motor other than the MM-EFS or MM-THE4 or an SPM motor, set "8009, 8109, 9009, or 9109" in
Pr.998.
