6.5 Resolver position tuning
• Resolver position tuning is required when a PM motor with a resolver is driven. The measured offset value between the
motor home magnetic pole position and the resolver home position is stored. Only the resolver position tuning can be
performed when offline auto tuning is not required, such as when the parameters for motor constant are set manually, or
when offline auto tuning is already performed.

Before performing resolver position tuning
• Check that the FR-A8APR, a motor, and a resolver are properly connected.
• Check that a motor (single, stop status) is connected. (Check that the motor is not rotated by an external force during
tuning.)
• Check that the mechanical brake is released.
• Check that the vector control (speed control) for the PM motor with a resolver is selected (refer to
page 30 ).
NOTE
• The resolver position tuning is required when a PM motor is used. (It is disabled when an induction motor is used.)
• When auto tuning is performed at the setting of
Pr.96 ="101", offline auto tuning and the resolver position tuning can be
performed at the same time (refer to page 31 ).

Setting
• To perform tuning, set Pr.373 ="1".
