Troubleshooting (Causes and Countermeasures for Key Errors)
Error No. Error name Cause Countermeasure
ACF AC power cutoff Momentary power failure has occurred or
the voltage has dropped. 100 V is input while the controller’s voltage specification is 200 V.
Check the power-source voltage. If the last digit of the controller’s model number is “-1,” the power specification is 100 V. If the last digit is “-2,” the power specification is 200 V.
ErG Emergency stop
(This is not an error.)
Emergency-stop signal is input. Emergency-stop signal is input in the following
condition: 1. The emergency-stop button on the teaching
pendant is pressed.
2. The applicable input terminal in the system
connector is turned ON.
3. The port switch on the front panel is set to the
manual side.
(The teaching-pendant/PC-software connector is
not connected.)
4. The actuator is of sensor specification and the slider
is stopped on either end of the slider.
dSF Deadman switch OFF The switch is set to the manual side even
when the teaching-pendant connector or other connector is not connected.
Set the switch to the auto side when the teaching- pendant connector or other connector is not connected.
CA5 Stop deviation overflow error Operation is mechanically disabled.
If there is no problem in the mechanical function, the power stage board is faulty.
Check to see if the actuator mounting bolts are contacting inside the axes, or if the slider attachment is contacting any surrounding mechanical parts. Replace the board.
C6b Deviation overflow error Operation is mechanically disabled. Check to see if the actuator mounting bolts are
contacting inside the axes, or if the slider attachment is contacting any surrounding mechanical parts.
d03 Encoder count error The encoder is faulty or dust is attached. Remove the motor cover and apply cleaning air spray
for OA equipment, etc., over the cord wheel. If the problem persists, replace/readjust the encoder.
