Alarm Group E: Supply Voltage/Power Capacity Abnormality Alarm

An abnormality occurred in the power supply voltage and capacity supplied to the rear of the ELECYLINDER.

No.	Cause	Countermeasure
1	The ELECYLINDER may be being used under conditions exceeding the specifications.	Check the specification values such as payload, acceleration/deceleration and speed, and adjust them appropriately.
2	The power supply voltage has been detected outside the range of 21.6 to 26.4V.	[Countermeasure 1] Inspect with a tester to see whether the power supply voltage is in the range of 21.6V to 26.4V. If it is out of range, the 24V DC power supply voltage has insufficient capacity. Check the necessary capacity and improve the power supply environment. Confirm that there is no gap in the voltage between 24V and 0V on the 24V power supply side from the voltage between 24V to 0V on the EC side.
2		[Countermeasure 2] Check if the total length of an actuator cable and a power & I/O cable is 10m or less, and whether the wire diameter is smaller than the applicable value. Make sure the wiring processing is correct. For Models with Pulse Motor Equipped Refer to Way of Wiring (for Connect to PIO Control / Connector) or Way of Wiring (for Connect to PIO Control / Cables). For Models with 24V AC Servomotor Equipped Refer to Way of Wiring (for Connect to PIO Control / Connector) or Way of Wiring (for Connect to PIO Control / Cables). For Models with 200V AC Servomotor Equipped Refer to Way of Wiring (for Connect to PIO Control / Connector) or Way of Wiring (for Connect to PIO Control / Cables).
3	Overcurrent has occurred on the I/O output part.	Check if the current has exceeded the rated output current on the I/O output part. If it is exceeded, set the output current to fall into the rated range, and then reboot the power supply. Check if there is a connectivity error to the host device. Make sure it is established correctly and then reboot the power.
4	If this alarm recurs after performing the inspection above and improving the power supply environment, it is highly likely that the controller has failed.	Replace the motor unit. For details, refer to the Instruction manual for each ELECYLINDER, Maintenance and Inspection.
