The DC voltage of the main circuit fell beloww the specificed value while
the RUN Command Input was ON
Overcurrent flowed to the IGBT. Servomotor power line ground fault
or short circuit
Operation was performed with torque significantly exceeding the rated
level for several seconds to several tens of seconds.
The regeneration energy exceeded the prosessing capacity of the
regeneration resistor.
The encoder wiring is disconnected.

Data from the encoder is abnormal.
The number of accumulated pulses in the deviation counter exceeded
the seting in the Deviation Counter Overflow Level (Pn63)
The servomotor exceeded the maximum number of rotations.
If the torque function was used, the Servomotor´s rotation speed
exceeded the settings in the Overspeed Detection Level Setting
(Pn70 and Pn73)
Overspeed
Electronic gear setting error
Deviation counter overflow
Overrun limit error
Parameter error
Parameter corruption
Drive prohibit input error
Encoder phase Z error
Encoder CS signal error
Encoder CS signal error
LSI setting error
Other errors
The section in Electronic Gear Ratio Numerator 1 (Pn46) or Electronic
Gear Ratio Numerator 2 (Pn47) is appropriate.
The number of accumulated pulses for the deviation counter
exceeded 134,217,728.
The servomotor exceeded the allowable operating range set in the
Overrun Limit Setting (Pn26).
Data in the parameter saving area was corrupted when data was
read from the FEPROM at power ON.
The checksum didn´t match when data was read from the FEPROM
at power ON.
The forward drive prohibit and reverse drive prohibit inputs are both
turned OFF.
A phase-Z pulse was not detected regularly
A logic error of the CS signal was detected
The combination of the Servomotor and Servo Drive is not appropriate.
The encoder was not connected when the power supply was turned ON.
Excessive noise caused the LSI setting not to be completed properly.
The servo Drive´s self-diagnosis function detected an error in the Servo
Drive.
