Motor Overload Protec-
tion
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 output
current
Overvoltage Motor coasts to a stop if DC bus voltage exceed 820 V
Undervoltage Stops when DC bus voltage is approx. 400 V or less
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 to individual levels during acceleration/constant-speed oper-
ation, 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 Indica-
tion
ON until the DC bus voltage becomes 50 V or less. Charge LED is pro-
vided.
Multi-function
