Instantaneous Over-
current
Motor coasts to a stop at approx. 250% or more of Inverter rated current
Overload Motor coasts to a stop after 1 minute at 150% of Inverter rated output cur-
rent
Overvoltage Motor coasts to a stop if DC bus voltage exceeds 820 V
Undervoltage Stops when DC bus voltage is approx. 400 V or less
Momentary Power
Loss
The following items are selectable: Not provided (stops if power loss is 15
ms or longer), continuous operation if power loss is approx. 0.5 s or short-
er, continuous operation.
