18.4.2 Troubleshooting when "24 V ERROR" lamp turns on
(1) When overvoltage is applied to the control circuit in the servo amplifier, power supply to the circuit will be
shut off and the "24 V ERROR" lamp will turn on. Then, the 3-digit, 7-segment LED on display will turn
off. Immediately turn off the power and check the wiring, etc. to the main circuit power supply (48 V DC).
(2) If the "24 V ERROR" lamp turns on with the 3-digit, 7-segment LED on, the control circuit power supply
voltage (24 V DC) may be failure. Check that the voltage of the control circuit power supply is 21.6 V DC
or more.
