Specification list
*1. When undervoltage or instantaneous power failure occurs, no alarm output is provided but
the output is shut off. After power restoration, the inverter may be run as it is. Depending on
the running status (e.g. load magnitude), however, overcurrent, regenerative overvoltage or
other protection may be activated at power restoration. (in the external operation mode)
*2. 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 an optional brake unit (BU) when regenerative energy
is large.
*3. Compatible with only the product having the built-in cooling fan.
*4. Available for the FR-S520E-0.4K to 3.7K-NA only.
*5. Activated only when "1" is set in Pr. 40 "start-time ground fault detection selection".
*6. Activated only when external thermal relay input (OH) is selected in any of Pr. 60 to Pr. 63
(input terminal function selection).
*7. Temperature applicable for a short period such as transportation.
