16. 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.
(2) Check whether there are any loose connections between the controller and actuator.
If contact failure occurs with the motor powerwiring, the motor power will be insufficient, which reduces the
holding force.
Because of this, the actuator moving part will fall downward in a vertical operation.
(In this operation, the lock function of the actuator with lock does not work).
The surge voltage generated by contact failure may damage the controller.
(3) The ambient temperature of the controller should be lower than 55
℃
depending on the operating
conditions of the actuator.
For the LEY40 and LEYG40 series, if the vertical transfer load is greater than the weight listed below, the
controller must be used at an ambient temperature of 40
o
C or less. Otherwise, damage may occur due to
higher temperature of the controller.
