The DC voltage in the main circuit is abnormally high.
The DC voltage of the main circuit is low.
Overcurrent flowed to the IGBT. Motor power line ground fault or short
circuit.
The temperature of the drive radiator exceeded the specified value.
Operation was performed with torque significantly exceeding the rating for
several seconds to several tens of seconds.
The regenerative energy exceeds the processing capacity of the
Regeneration Resistor.
The encoder wiring is disconnected.
Communications cannot be performed between the encoder and the drive.
The number of accumulated pulses in the error counter exceeded the set
value for the Error Counter Overflow Level (Pn014).
During full closing control, difference between position of load from external
encoder and position of motor due to encoder was larger than the number

Setting (Pn514) with respect to the position command input.
Data in the Parameter Save area was corrupted when the power supply
was turned ON and data was read from the EEPROM.
The checksum for the data read from the EEPROM when the power supply
was turned ON does not match.
The forward drive prohibition and reverse drive prohibition inputs are both
turned OFF.
The voltage supplied to the absolute encoder is lower than the specified
value.
