Selecting the PM sensorless vector control
 Initializing the parameters required for the PM sensorless vector
control (Pr.998)
• PM parameter initialization sets parameters required for driving an EM-A motor.
• Two methods of the motor parameter initialization are available: using Pr.998 PM parameter initialization, and
using IPM parameter initialization ("
Pr. Name
998 PM parameter
E430 initialization
• 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 "3003, 3044, 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 "3103, 3144, 8109, or 9109" in
Pr.998.
• Set Pr.998 = "0" to change the PM sensorless vector control parameter settings to the parameter settings
required to drive an induction motor.
• When using an IPM motor or SPM motor other than EM-A or MM-CF, set Pr.998 = "8009, 8109, 9009, or 9109".
