Surrounding air humidity
Available when the option (FR-A8AP) is mounted.
Temperature applicable for a short time, e.g. in transit.
For the installation at an altitude above 1,000 m up to 2,500 m, derate the rated current 3% per 500 m.
This protective function is not available in the initial status.
In the initial setting for the the FR-A846-00170(5.5K) or higher, it is limited to 150% by the torque limit level.
or less for the FR-A846-01800(55K) or higher.
