VECTOR CONTROL
NOTE
• For PM motors, after performing offline auto tuning and resolver position tuning, first perform PM parameter
initialization. If parameter initialization is performed after setting other parameters, some of those parameters will be
initialized too. (For the parameters to be initialized, refer to the Instruction Manual (Detailed) of the inverter.)
6.3 Vector control for PM motor with resolver
• With the FR-A8APR, PM motors with a resolver can be driven under vector control. (For the setting of vector control for an
induction motor, refer to the Instruction Manual (Detailed) of the inverter.)
The setting values of 100 and above are used when the fast-response operation is selected.
The operation for the setting of "0 or 100" is performed when "1, 2, 101, or 102" is set.
The operation for the setting of "4 or 104" is performed when "5 or 105" is set.
Speed control under PM sensorless vector control when the FR-A8APR is not installed.
The operation for the setting of "20 or 110" is performed when "10 to 14, or 111 to 114" is set.
When a PM motor is used, set
Pr.80
and
Pr.81
according to the motor. Setting "9999" disrupts proper operation.
