Surrounding air temperature
The braking torque indicated is a short-duration average torque (which varies with motor loss) when the motor alone is decelerated from 60Hz in the
shortest time and is not a continuous regenerative torque. When the motor is decelerated from the frequency higher than the base frequency, the average
deceleration torque will reduce. Since the inverter does not contain a brake resistor, use the optional brake resistor when regenerative energy is large. A
brake unit (FR-BU2) may also be used.
As the 0.75K or less are not provided with the cooling fan, this alarm does not function.
This operation guide is only available with option parameter unit (FR-PU07).
This protective function does not function in the initial status.
This protective function is available with the three-phase power input specification model only.
When using the inverters at the surrounding air temperature of 40°C or less, the inverters can be installed closely attached (0cm clearance).
Temperatures applicable for a short time, e.g. in transit.
