Motor Overload
Protection
Electronic thermal overload relay
Instantaneous Overcurrent
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 out-
put current
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 ap-
prox. 0.5 s or shorter, continuous operation.
Heatsink Overheat
Protected by electronic circuit.
Stall Prevention Level
Can be set to individual levels during acceleration/constant-speed
operation, provided/not provided available during deceleration.
Cooling Fan Fault
Protected by electronic circuit (fan lock detection).
Ground Fault
*3
Protected by electronic circuit (overcurrent level).
Power Charge
Indication
ON until the DC bus voltage becomes 50 V or less. Charge LED is
provided.
Multi-func-
tion Input
Seven of the following input signals are selectable: Forward Run
Command, Reverse Run Command, Forward/Reverse Run (3-wire
sequence) Command, Fault Reset, external fault, multi-step speed
