continuous output current.
Overvoltage Motor coasts to a stop if converter output voltage exceeds
800 V. (approx. 700 V) (see Note 3)
Undervoltage Motor coasts to a stop if converter output voltage drops to
420 V or below.
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.) Setting made before shipment.
