If the motor is restrained, or rapidly accelerated or
decelerated, a large current flows through the
Inverter, which may result in breakdown.
To avoid this, an overcurrent protection circuit works
to shut off the Inverter output.
If an Inverter output current is detected and the motor is overloaded,
an electronic thermal inside the Inverter operates to shut off the
Inverter output.
•After a trip occurs, normal operation is restored in 10 seconds by
resetting the Inverter.
If the incoming voltage and regenerative energy from the motor are too
high, a protection circuit works to shut off the Inverter output when the
voltage on the converter exceeds the specified level.
Shuts off the output if an error occurs in the EEPROM built into the
Inverter due to external noise and abnormal temperature rise.

off the power after completing data initialization.
Shuts off the output if the incoming voltage drops below the specified
level, causing the control circuit not to work properly during a
momentary power interruption.
Shuts off the output if the internal CPU has malfunctioned.
•If the multi-function output terminal (relay terminal) is set to 05
(alarm), the signal may not be output during the CPU
error . In this case, no data is stored in the trip monitor.

•The same thing could happen if AL (05) is allocated to the relay
output terminal. Again, no data is stored.
If an error occurs in the external equipment or devices, the Inverter
receives the signal, and the output is shut off.
