T)
Instantaneous Overcur-
rent
Motor coasts to stop at approx. 200% rated output current.
Fuse Protection Motor coasts to stop at blown fuse.
Overload Motor coasts to stop after 1 min. at rated overload capacity.
Overvoltage
Motor coasts to a stop if converter output voltage exceeds 410VDC
(820VDC at 460V input)
Undervoltage
Motor coasts to stop if converter output voltage drops below user
adjustable value
