ERROR CODE LIST
2.4 Errors
DA8EEC-91-210-A0
2.4-13
1835
Over speed error
DESCRIPTION
Motor rotating speed has exceeded the set value.
CAUSE
Motor rotating speed exceeded the set value of acceleration level setting.
SOLUTION
Check for any excessive speed command issued. If overshoot occurred due to improper adjustment of gain, adjust
the gain.
NOTE
1836
Command abnormal error
DESCRIPTION
Operation command caused an error.
CAUSE
Operation command value may not be set properly.
SOLUTION
Check that improper command has not been entered.
NOTE
1837
External scale communication data abnormal error
DESCRIPTION
Data from the external scale caused communication error.
CAUSE
Data may be abnormal due to noise.
SOLUTION
Secure the power supply voltage 5V DC±5% of the external scale. Use care especially when the external scale
cable is long. Separate the motor cable from the external scale cable if connected together. Connect the shield to
the FG.
NOTE
1838
Deviation counter overflow error
DESCRIPTION
Deviation counter value has exceeded the set value.
CAUSE
Deviation counter exceeded 2
27
(134217728) pulse.
SOLUTION
Check if the motor rotates according to the position command pulse. Check the torque monitor and make sure the
output torque is not saturated.
NOTE
1839
Software limit error
DESCRIPTION
Position command input range has exceeded the motor movable range.
CAUSE
The gain is not matched.
The value of software limit setting is small.
SOLUTION
Check the gain and inertia ratio.
Increase the software limit set value.
NOTE
1840
External scale communication abnormal error
DESCRIPTION
External scale communication error was detected.
CAUSE
Communication between the external scale and servo amplifier was interrupted more than a given count, which
activated the disconnection detection.
SOLUTION
Perform wiring of the external scale as indicated.

1841
EEPROM Parameter abnormal error
DESCRIPTION
EEPROM parameter error for the servo amplifier was detected.
CAUSE
When reading the data from the EEPROM at power ON, the parameter save area data was found to be destroyed.
SOLUTION
Set all parameters again. If the error persists, the EEPROM may be defective.
NOTE
1842
EEPROM Check code abnormal error
DESCRIPTION
EEPROM check code error for the servo amplifier was detected.
CAUSE
When reading the data from the EEPROM at power ON, the EEPROM write check data was found to be destroyed.
SOLUTION
The EEPROM may be defective.
NOTE
1843
Drive prohibition input abnormal error
DESCRIPTION
Abnormal drive prohibition input signal of the servo amplifier was entered.
CAUSE
Both of the drive prohibition inputs (CW, CCW) opened.
SOLUTION
Check for abnormality in the switch, wires and power supply connected to the prohibition inputs (CW, CCW).
Especially check for slow rise time of the control signal power.
NOTE
1844
Absolute encoder system breakdown error
DESCRIPTION
Absolute encoder system breakdown error was detected.
CAUSE
Built-in capacitor voltage dropped to below the rated value because the supply power to the absolute encoder and
battery power ran down.
SOLUTION
Connect the battery power and clear the absolute encoder.
NOTE
1845
Absolute counter overflow error
DESCRIPTION
Absolute counter overflow error was detected.
CAUSE
The multiple rotation counter of the absolute encoder exceeded the rated value.
SOLUTION
Set the absolute encoder setting to a proper value. Set the displacement from the machine origin to within 32767
rotations.
NOTE
1846
Absolute over speed abnormal error
DESCRIPTION
Absolute over speed abnormal error was detected.
CAUSE
The rotating speed of the motor exceeded the rated value while battery power only was being supplied at power
failure.
SOLUTION
Check the power voltage on the encoder side.

1847
Absolute 1 round counter abnormal error
DESCRIPTION
Absolute single rotation counter error was detected.
CAUSE
Absolute encoder detected a single rotation counter error.
SOLUTION
Replace the servomotor.
NOTE
1848
Absolute multi round counter abnormal error
DESCRIPTION
Absolute multiple rotation counter error was detected.
CAUSE
Absolute encoder detected a multiple rotation counter error.
SOLUTION
Replace the servomotor.
NOTE
1849
Absolute status abnormal error
DESCRIPTION
Absolute status error was detected.
CAUSE
Absolute encoder rotated at the rated value or more at power ON.
SOLUTION
Do not let the motor move when turning power ON.
NOTE
1850
Encoder Z phase abnormal error
DESCRIPTION
Missing pulses of serial encoder Z-phase were detected.
CAUSE
Encoder is at fault.
SOLUTION
Replace the servomotor.
NOTE
1851
Encoder CS signal abnormal error
DESCRIPTION
CS signal logic error of serial encoder was detected.
CAUSE
Encoder is at fault.
SOLUTION
Replace the servomotor.
NOTE
1852
External scale status 0 error
DESCRIPTION
External scale error was detected.
CAUSE
The bit 0 of the error code of the external scale changed to 1.
SOLUTION
Eliminate the cause of the error and execute the command to clear the external scale error. Then turn the control
power OFF once and turn it back ON.
NOTE
