2. Product Outline
2.1 Outline of battery-less absolute encoder
(1) What is a Battery-Less Absolute Encoder?
The Battery-Less Absolute Encoder is an encoder which can detect the absolute position of multiple
rotations. The battery of this encoder does not back up the information of the multiple rotation whilst the
absolute encoder for single rotation does. Because of this, battery replacement is not required.
Detection of the absolute position enables the encoder to detect the actuator position when power is
supplied, so operation is available with no return to origin operation.

(2) When is the return to origin operation required?

1) When the power is applied for the first time.
2) When the actuator or motor is replaced.
3) When alarm “Group E” is cleared by re-applying the power.
(E.g.) When the encoder wiring is disconnected when the power is supplied.
- Encoder error (code: 01-192)

Warning
Do not use in an environment where a 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 of failure may occur.
Do not expose the actuator motor to a magnetic field with a magnetic flux density of 1 mT or more.
Please read 16. Individual Precautions for Battery-Less Absolute Encoder.

Warning
Please check that there is no incorrect wiring or loose connections between the controller and
actuator.
If contact failure occurs in the motor power wiring, the motor power will be insufficient even in the Servo ON
state, which will reduce 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.
Please make sure that there is no incorrect wiring or loose connections between the controller and actuator
before use.

Caution
[Precaution when using the controller for the first time]
Reset the alarm.
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 battery is replaced, so an alarm reset is necessary.
(Resetting the alarm registers the absolute encoder specific ID No. in the controller).
Conducting a Return to Origin operation after the alarm reset allows the use of the controller.

 Caution
Refer to this manual for the procedure for returning to the origin position of the controller and the recovery
operation after power is re-applied. Refer to the Operation Manual of the Controller for the JXC □ 1 Series
for the basic operation method.

Caution
Please keep this manual in a safe place for future use. It will be necessary to refer to this manual along
with the teaching box and the configuration software manuals at installation and during fault finding.

11. Operations
11.1 Return to origin position
Return to origin operation should be performed first in the following cases:.
(1) When power is applied for the first time.
(2) When the actuator or motor is replaced.
(3) When alarm “Group E” is cleared by applying the power again.
For (1) and (2), Alarm No.10-153 “Absolute encoder ID Alarm error” is generated after the power is
applied, so perform the return to origin operation after resetting the alarm.

■Return to origin operation

The actuator moves in the return to origin direction (* this direction is dependent on the actuator) from the
initial position at the moment of power ON. Refer to (1) in the figure below.
When the actuator reaches the end of travel limit it pauses for a short time. The controller recognizes the
position as the end of travel limit of the actuator. Then, the actuator moves at a low speed in the direction
opposite to the return to origin direction: Refer to (2) in the figure below.
The position after the travel becomes the origin.

12.1 Procedure for start up
Procedure for start up of the battery-less absolute encoder for every occasion when the power is applied.

(1) When power is supplied for the first time (Refer to 12.2 for details)
In the following cases, Alarm No.10-153 “Absolute encoder ID does not match controller data” is
generated after the power is applied, so perform the return to origin operation after resetting the alarm.

In addition, "When power is supplied for the first time" indicates the following cases.
- When connecting the electric actuator and turning on the power for the first time after purchase.
- When the actuator or motor has been replaced.
- When replacing the controller.

If the electric actuator and controller have been purchased as a set part number, the alarm may not be
generated by the customer because the alarm No. 01-153 “Absolute encoder ID does not match controller
data” is reset at the factory.
(If multiple units are purchased with the same set part number, alarm No. 01-153 “Absolute encoder ID
does not match controller data” will occur depending on the combination of the connected electric actuator
and controller.)

(2) When the power is supplied again (Refer to 12.3 for details)

(3) Alarm (group E) is cleared by a cut to the power supply (Refer to 12.4 for details).
SETON output is turned OFF. Perform return to origin operation.
When the power is applied again after changing Return to origin parameter “Return to Origin
Direction”, follow the same start up procedure.

Details of the alarm for motor control can be checked using a PC (the controller configuration software) or a
teaching box.
* Please refer to the manuals for the controller configuration software or the teaching box for details of the
alarms
When an alarm is generated, deactivate the alarm after troubleshooting and correcting the error with
reference to 15.2 Alarm and countermeasures.
Alarms are divided into two types. One is alarm group B to D which can be cleared by inputting the signal
RESET. The other is group E which cannot be cleared unless the power supply (24 VDC) is turned OFF.

15.1 Alarm group output

This product outputs a signal to distinguish the type of the alarm when an alarm is generated.
Alarms are classified into 5 groups. When an alarm is generated, it is output in OUT0 to OUT3.
The table below shows the combination of the alarm group and signal (OUT0 to OUT3).

Signal
Alarm group
ALARM OUT0 OUT1 OUT2 OUT3
Alarm group B ON OFF ON OFF OFF
Alarm group C ON OFF OFF ON OFF
Alarm group D ON OFF OFF OFF ON
Alarm group E ON OFF OFF OFF OFF

After generation of the alarm, SVRE or SETON are output according to the contents of the alarm as shown
below.

Alarm group B No change No change Turn ON RESET
Alarm group C No change No change Turn ON RESET
Alarm group D OFF No change Turn ON RESET, SVON

- Procedure to restart operation when alarm group D is generated -

Procedure 1 Alarm group D is generated → "SVRE" changes to OFF (Servo is OFF)
Procedure 2 Turn ON RESET → (Alarm is cancelled) → After turning ON SVON, SVRE is turned ON (Servo

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.
40

40
40
40

40

40
40

40

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 40oC 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

-31-

JXC※-OMX0018
 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.

Refer to the Operation Manual of the controller and actuator for precautions.
