Motor coasts to a stop at approx. 200% of inverter rated
current
Motor coasts to a stop after 1 minute at 150% of inverter
rated output current
Motor coasts to a stop if DC bus voltage exceed 820V
Stops when DC bus voltage is approx. 400V or less
Following items are selectable : Not provided (stops if
power loss is 15ms or longer), continuous operation if
power loss is approx. 0.5s or shorter, continuous operation
