Mitsubishi FR-A800

Control method
172
PARAMETERS
5.2.4 Selecting the PM sensorless vector control
Selecting the PM sensorless vector control by performing parameter
initialization on the operation panel ( )
POINTPOINT
• The parameters required to drive an MM-CF IPM motor are automatically changed as a batch. (Refer to page 174.)
• [PM] on the operation panel (FR-DU08) is on when the PM sensorless vector control is set.
NOTE
• If parameters are initialized for a PM motor in the IPM initialization mode, the Pr.998 PM parameter initialization setting is
automatically changed.
• In the initial parameter setting, the capacity same as the inverter capacity is set in Pr.80 Motor capacity. To use a motor
capacity that is one rank lower than the inverter capacity, set Pr.80 Motor capacity by selecting the mode on the operation
panel.
• To set a speed or to display monitored items in frequency, Pr.998. (Refer to page 173.)
