Overvoltage Motor coasts to a stop if converter output voltage exceeds
800 V.
Undervoltage Motor coasts to a stop if converter output voltage drops to
420 V or below (See Note 3).
Momentary power loss Immediately stop by 15 ms and above momentary power loss.
(Continuous system operation during power loss less than
2 sec is equipped as standard. See Note 2.) Setting made
before shipment.
Fin overheat Thermostat
Stall prevention Stall prevention at acceleration/deceleration and constant
speed operation
Protective functions Ground fault Provided by electronic circuit
Power charge indication Charge lamp stays ON until bus voltage drops below 50 V.

Note 1. Our standard 4-pole motor is used for max applicable motor output.
2. Allowable values for the applications not required overload.
3. For Models of 4.1 kVA or less, continuous system operation during power loss less than 1 sec, for
models with capacitor (option), less than 2 seconds.
4. Temperature during shipping (for short period).
