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 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/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
Seven of the following input signals are selectable: Forward run com-
mand, reverse run command, forward/reverse run (3-wire sequence),
fault reset, external fault, multi-step speed operation, JOG command,
acceleration/deceleration time select, external baseblock, SPEED
SEARCH command, ACCELERATION/DECELERATION HOLD com-
mand, LOCAL/REMOTE selection, communication/control circuit termi-
nal selection, emergency stop fault, emergency stop alarm, UP/DOWN
command, self-test, PID control cancel, PID integral reset/hold, Inverter
overheat alarm
