(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.
LEY40□EA: 9 kg, LEY40□EB:19 kg, LEY40□EC:38 kg
LEYG40□EA:7 kg, LEYG40□EB:17 kg, LEYG40□EC:36 kg
Caution
(1) Supply power when the actuator is stationary.
The controller acquires the absolute position data from the absolute encoder when power is applied.
Therefore, if the power is applied to the controller when the actuator is moving with an external force, the
controller fails to acquire the absolute position data, which generates an alarm.
(2) When the controller is used for the first time, perform the offset adjustment.
Alarm “Absolute encoder ID Alarm error (code: 1-153)” will be generated when power is applied to the
controller for the first time and/or when the actuator is replaced, therefore reset the alarm.
(Resetting the alarm registers the absolute encoder specific ID No. in the controller)
Turn the servo ON after resetting the alarm. Conducting a Return to Origin operation allows the use of the
controller.
(3) When a blank controller and actuator absolute encoder with battery are used, write the parameter
for the actuator to the absolute encoder with battery before use.
although the actuator type is identical, the actuator parameter in which the encoder and motor
specifications are not identical are written, noise or vibration occurs during servo ON or operation.
If the parameter for the actuator with different specification is written, re-write the parameter for the actuator
with the battery-less absolute encoder using JXC-BCW.
