Motor protection Protection by electronic thermal.
Instantaneous
overcurrent
protection Stops at approx. 200% of rated output current.
Overload
protection Stops in one minute at approx. 150% of rated output current.
Overvoltage
protection Stops when main-circuit DC voltage is approx. 820 V.
Undervoltage
protection

er interruption
compensation
(selection) Stops for 15 ms or more. By selecting the momentary power interruption mode, operation can be continued if power is
restored within 2 s.
Cooling fin over-
heating Protection by thermistor.
Grounding
protection Protection by electronic circuits.
