*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 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. This function is valid for only the type with RS-485 communication function.
*4. Compatible with only the product having the built-in cooling fan.
*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).
