2
T)
Instantaneous Overcurrent Motor coasts to stop at approx. 180% 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 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
