If the motor is restrained or rapidly accelerated or
decelerated, a large current flows through the
Inverter, which may result in breakage.
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 works to shut off the Inverter
output.
If the usage rate of the braking resistor is exceeded, this function
detects overvoltage through the operation stop of the control circuit
and shuts off the Inverter output.
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.
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 worked erroneously or
abnormally.
If an error occurs in the external equipment or devices, the Inverter
receives the signal, and the output is shut off.
(Available with the external trip function selected)
Appears if the Inverter is turned on with the RUN command being
input. (Available with the USP function selected)
Shuts off the output if a ground fault between the Inverter output unit
and the motor is detected when turning on the power.
Appears if the incoming voltage has remained high for 100 seconds
while the Inverter output is stopped.
