11
Power supply
undervoltage
The DC voltage of the main circuit fell below the specified value.
Yes
12
Overvoltage
The DC voltage of the main circuit is abnormally high.
Yes
14
Overcurrent
Overcurrent flowed to the IGBT. Servomotor power line ground fault
or short circuit.
No
15
Built-in resistor overheat
The resistor in the Servo Drive is abnormally overheating.
No
16
Overload
Operation was performed with torque significantly exceeding the rat-
ed level for several seconds to several tens of seconds.
Yes
18
Regeneration overload
The regeneration energy exceeded the processing capacity of the
regeneration resistor.
No
21
Encoder disconnection
detected
The encoder wiring is disconnected.
No
23
Encoder data error
Data from the encoder is abnormal.
No
24
Deviation counter
overflow
The number of accumulated pulses in the deviation counter exceed-
ed the setting in the Deviation Counter Overflow Level (Pn63).
Yes
26
Overspeed
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).
Yes
27
Electronic gear setting
error
The setting in Electronic Gear Ratio Numerator 1 (Pn46) or Electron-
ic Gear Ratio Numerator 2 (Pn47) is not appropriate.
Yes
29
Deviation counter
overflow
The number of accumulated pulses for the deviation counter
exceeded 134,217,728.
Yes
34
Overrun limit error
The Servomotor exceeded the allowable operating range set in the
Overrun Limit Setting (Pn26).
Yes
36
Parameter error
Data in the parameter saving area was corrupted when data was
read from the EEPROM at power ON.
No
37
Parameter corruption
The checksum didn’t match when data was read from the EEPROM
at power on.
No
38
Drive prohibit input error
The forward drive prohibit and reverse drive prohibit inputs are both
turned OFF.
Yes
44
Encoder counter error 1
The encoder detected an error in the counter.
No
45
Encoder counter error 2
The encoder detected an error in the counter.
No
48
Encoder phase Z error
A phase-Z pulse was not detected regularly.
No
49
Encoder CS signal error
A logic error of the CS signal was detected.
No
95
Servomotor
non-conformity
The combination of the Servomotor and Servo Drive is not appropri-
ate.
The encoder was not connected when the power supply was turned
ON.
No
96
LSI setting error
Excessive noise caused the LSI setting not to be completed proper-
ly.
No
Others
Other errors
The Servo Drive’s self-diagnosis function detected an error in the
Servo Drive.
No
