As the 0.75K or lower are not provided with the cooling fan, this alarm does not function.
This operation guide is only available with option parameter unit (FR-PU07). (Some functions are not supported.)
This protective function is not available in the initial status.
When using the drive units at the surrounding air temperature of 40°C or less, the drive units can be installed closely attached (0cm clearance).
Temperatures applicable for a short time, e.g. in transit.
The maximum speed varies by motor type (rating) when a motor other than the S-PM geared motor is used.
