Alarm Group A: Overload Alarm
Moving parts of ELECYLINDER stopped abnormally while moving to the target position.
No. | Cause | Countermeasure |
|---|---|---|
1 | Operation may not be possible due to contact with or snagging on external obstacles. | Remove any external obstacles or other external loads. |
2 | 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. |
3 | Causes may include foreign matter, brake failure or motor failure. | Visually check for the depletion of grease on the ball screw / guide inside the ELECYLINDER, intrusion of foreign matter, etc. If this is the case, clean the inside of the ELECYLINDER and replenish the grease. |
Check the sliding movement of the ELECYLINDER body. If there is no abnormality in the sliding motion, there is a possibility of motor or brake failure. Replacement of the motor unit is recommended. | ||
4 | The base may have been distorted when mounting the ELECYLINDER, increasing the sliding resistance of the guide. | The ELECYLINDER mounting surface should be a machined surface or a plane with similar accuracy, have its flatness at 0.02mm/m max. and straightness at 0.01mm max. Refer to the instruction manual of each ELECYLINDER [How to Install] for the recommended tightening torque of the bolt for fixing the base. |
5-1 | [For Models with Pulse Motor Equipped] The peak power capacity of the 24V power supply is less than 2.0A. | Use a power supply with peak current of 2.0A or higher (per axis). |
5-2 | [For Models with 200V AC Servomotor Equipped] The power voltage on 100V AC (or 200V AC) has dropped. | Check on the power voltage of 100V AC (or 200V AC). In case it has been dropped, take a counteraction so it gets back to the specified power voltage. In case a cable below AWG14 is used, apply one with AWG14. |
6 | The resistance is high because the cables used are those with their wire diameter less than AWG18. Or, there is a contact error at the connector terminal which has blocked the flow of peak current. | Make sure that the wiring for power supply use is AWG18 and that there is no looseness, contact failure, disconnection or the like at the connection terminal/connector etc. |
7 | The deceleration distance was insufficient and the calculation result of the arrival position exceeded the operation range of the ELECYLINDER due to the next movement command being issued too soon during operation with Smooth accel/decel setting enabled. | Adjust the timing of the next movement command so that the command will be given after the first movement is completed. |
8-1 | [For Models with Pulse Motor Equipped] 24V power was turned ON while the moving parts of the ELECYLINDER were immobilized or pressed against the mechanical stopper. | Resolve the state of immobilization. If the unit is pressed against the mechanical stopper, move it at least 5mm away, then turn on the power again. |
8-2 | [For Models with 200V AC Servomotor Equipped] 24V DC and 100V AC (or 200V AC) was turned ON while the moving parts of the ELECYLINDER were immobilized or pressed against the mechanical stopper. | Resolve the state of immobilization. If the unit is pressed against the mechanical stopper, move it at least 5mm away, then turn on 24V DC and 100V AC (or 200V AC) again. |
