∗1
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.
∗2
Temperatures applicable for a short time, e.g. in transit.
∗3
As the FR-E720-0.1K to 0.75K, FR-E740-0.4K and 0.75K, FR-E720S-0.1K to 0.4K, FR-E710W-0.1K to 0.75K are not provided with the cooling fan, this alarm
does not function.
∗4
When using the inverters at the surrounding air temperature of 40°C or less, the inverters can be installed closely attached (0cm clearance).
∗5
This protective function does not function in the initial status.
∗6
This protective function is available with the three-phase power input specification model only.
