20.7 Maintenance
Warning
(1) Perform maintenance checks periodically.
Confirm wiring and screws are not loose.
Loose screws or wires may cause unexpected malfunction.
(2) Conduct an appropriate functional inspection and test after completing maintenance.
In case of any abnormalities (if the actuator does not move, etc.), stop the operation of the system.
Otherwise, an unexpected malfunction may occur and it will become impossible to ensure safety.
Give an emergency stop instruction to confirm safety.
(3) Do not disassemble, modify or repair this controller or the peripheral devices.
(4) Do not put anything conductive or flammable inside of the controller.
Fire or explosion can result.
(5) Do not perform an insulation resistance test or insulation withstand voltage test.
(6) Ensure sufficient space for maintenance.
Design the system to allow the required space for maintenance.
20.8. Specific Precautions for Battery-Less Absolute Encoder
Warning
(1) Do not use in an environment where strong magnetic field is present.
A magnetic sensor is used in the encoder. Therefore, if the actuator motor is used in a strong magnetic
field environment, malfunction or failure may occur.
The major failure is described below.
- Reduction of transporting ability (pushing force, speed)
- Damage to the actuator due to collision to the workpiece by positional displacement occurred.
Do not expose the actuator motor to a magnetic field with a magnetic flux density of 1 mT or more.
When installing an electric actuator or an air cylinder with an auto switch (ex. CDQ2 series) or electric
actuators side by side, maintain 40 mm minimum around the motor.
Refer to the construction drawing of the actuator motor.
Air cylinder installation with an auto switch is forbidden in the shaded area.
