7.2 Common Specifications
*1. When undervoltage 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 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.
*3. Compatible with only the product having the built-in cooling fan.
*4. Activated only when external thermal relay input (OH) is selected in any of Pr. 60 to Pr.
63, Pr. 65 and Pr. 505 (input terminal function selection).
*5. Activated only when "1" is set in Pr.40 "start-time earth(ground) fault detection selection".
