Detection details and cause of error
The DC voltage of the main circuit fell below the specified value.
The DC voltage of the main circuit is abnormally high.
Overcurrent flowed to the IGBT. Servomotor power line ground fault
or short circuit.
The resistor in the Servo Drive is abnormally overheating.
Operation was performed with torque significantly exceeding the rat-
ed level for several seconds to several tens of seconds.
The regeneration energy exceeded the processing 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 exceed-
ed the setting in the Deviation Counter Overflow Level (Pn63).
The Servomotor exceeded the maximum number of rotations.
If the torque limit function was used, the Servomotor's rotation speed
exceeded the settings in the Overspeed Detection Level Setting
(Pn70 and Pn73).
The setting in Electronic Gear Ratio Numerator 1 (Pn46) or Electron-
ic Gear Ratio Numerator 2 (Pn47) is not 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 EEPROM at power ON.
The checksum didn't match when data was read from the EEPROM
at power on.
The forward drive prohibit and reverse drive prohibit inputs are both
turned OFF.
The encoder detected an error in the counter.
The encoder detected an error in the counter.
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 appropri-
ate.
The encoder was not connected when the power supply was turned
ON.
Excessive noise caused the LSI setting not to be completed proper-
ly.
The Servo Drive's self-diagnosis function detected an error in the
Servo Drive.
