2
T)
Instantaneous Overcurrent Motor coasts to stop at approximately 200% rated output current. (CT Rating)
Fuse Protection Motor coasts to stop at blown fuse.
Overload Motor coasts to stop after 1 min. at 150% rated output current. (CT Rating)
Overvoltage Motor coasts to stop if converter output voltage exceeds 410VDC (820VDC at 460V input, 1040VDC at 575V input)
Undervoltage Motor coasts to stop if converter output voltage drops below user adjustable value
Momentary Power Loss
Immediately stop after 15 ms or longer power loss. (Continuous system
operation during power loss less than 2s is equipped as standard.)
