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 exceed 410 V
Undervoltage Stops when DC bus voltage is approx. 200 V or less (approx. 160 V or
less for single-phase series).
Momentary Following items are selectable: Not provided (stops if power loss is 15 ms
Power Loss or longer), continuous operation if power loss is approx. 0.5 s or shorter,
continuous operation.
Heatsink Protected by electronic circuit.
Overheat
Stall Preven- Can be set individual level during acceleration/deceleration, provided/not
tion Level provided available during coast to a stop.
Cooling Fan Protected by electronic circuit (fan lock detection).
Fault
Ground Fault Protected by electronic circuit (overcurrent level).
Power ON until the DC bus voltage becomes 50 V or less. RUN indicator stays
Charge Indi- ON or Digital Operator indicator stays ON.
