Protective functions Motor overload protection Electric thermal overload relay
Instantaneous overcurrent Motor coasts to a stop at approx. 200% rated current.
Fuse blown protection Motor coasts to a stop by blown-fuse.
Overload Motor coasts to a stop for 1 minute at 150% rated output
current.
Overvoltage Motor coasts to a stop if converter output voltage exceeds
400 V.
Undervoltage Motor coasts to a stop if converter output voltage drops to
210 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.
