Available only when a vector control compatible option is installed.
For PM sensorless vector control, refer to the Instruction Manual (Detailed) of the FR-A800 inverter.
In the initial setting of the FR-A820-00340(5.5K) or higher and the FR-A840-00170(5.5K) or higher, it is limited to 150% by the torque limit level.
Enabled only for standard models and IP55 compatible models.
This protective function is not available in the initial status.
Enabled only for standard models.
Available for the IP55 compatible model only.
Temperature applicable for a short time, e.g. in transit.
For the installation at an altitude above 1000 m (up to 2500 m), consider a 3% reduction in the rated current per altitude increase of 500 m.
