Motor Overload
Protection
Electronic thermal overload relay
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 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
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.
Heatsink Overheat Protected by electronic circuit.
Stall Prevention Level Can be set to individual levels during acceleration/constant-speed opera-
tion, provided/not provided available during deceleration.
Cooling Fan Fault Protected by electronic circuit (fan lock detection).
Ground Fault
*4
Protected by electronic circuit (overcurrent level).
*3
Power Charge
Indication
ON until the DC bus voltage becomes 50 V or less. RUN indicator stays
ON or Digital Operator indicator stays ON.
Multi-function
Input
