Protective Functions
Motor Overload
Protection
Electronic thermal overload relay
Instantaneous
Overcurrent
Motor coasts to a stop at approx. 200% of Inverter rated cur-
rent
Overload Motor coasts to a stop after 1 minute at 150% of Inverter rat-
ed output current
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 Power
Loss
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 shorter, continuous operation.
Heatsink Overheat Protected by electronic circuit.
Stall Prevention
Level
Can be set individual level during acceleration/deceleration,
provided/not provided available during coast to a stop.
Cooling Fan Fault Protected by electronic circuit (fan lock detection).
Ground Fault
*6
Protected by electronic circuit (rated output current level).
Power Charge Indi-
