Starting Procedures
When using this product for the first time, make sure to avoid mistakes and incorrect wiring by referring to
the procedure below. “PC” stated in this section means “PC software”.
● Action to Take When Error Occurred
Shown below are the alarms that you may often see after power up. Have an appropriate treatment following
the instructions below.
Please refer to the Instruction Manual for other alarms.
Error Code Error Description Cause and Treatment
069
Real Time Clock Operation
Stop Detection
It indicates the calendar function has stopped and the current
time data has lost. Have the clock settings again from the
teaching tool.
0A5
Electromagnetic Brake
Release Failure Error
Brake could not be released for the electromagnetic brake
equipped type.
Check the 24V power supply for electromagnetic brake.
0CF I/O 24V Power Supply Error
An error is occurred in 24V power supply for PIO.
Check the voltage of the 24V power supply for PIO.
0E5 Encoder Receive Error
This error code appears when the right signal was not received
from the encoder side to the controller command. Check if any
wire breakage on a connector and the condition of wire
connections. If no error is generated under the condition that the
power to all the peripheral equipment is shut and operate only
this controller and the actuator, noise can be considered as the
cause of the problem.
0E7
A-, B- and Z-Phases
Breakage Error
It is the condition that the encoder signal is not properly
detected.
Check if any wire breakage on a connector and the condition of
wire connections.
0EE
Absolute Encoder Error
Detection 2
This error code appears when the absolute encoder PCB cannot
detect the position information properly. The voltage for the
absolute data battery is dropped. Check the battery alarm output
on PIO, and if it is off, replace the battery. Perform Absolute
Reset after the replacement.
Check the encoder cable connection.
20A Servo Off While in Operation
It shows the operation command was generated in the condition
that the servo is off.
Resume the operation after turning the servo on.

Check of Packed Items
Are there all the delivered items?
Please contact the distributor.
Point Check Item
• Is frame ground (FG) connected?
• Has the noise countermeasure been taken?
Power Supply and Alarm Check
Connect a teaching tool such as PC, turn the mode changeover
switch to “MANU” side and turn the power on for each unit.
Select [Teaching Mode 1 Safety Speed Activated / PIO
Operation Invalid] in the teaching tool such as PC.
Check Item
Is the orange light [ALM] on
the LED status display off?
Connect the PC or teaching
pendant and check the
content of the alarm to have
the right treatment.
Select Operation Mode
Positioner Mode Pulse Train Mode
Safety Speed Setting
Set it in Parameter No. 35 if necessary. The safety speed is set to 100mm/s at the delivery.
Servo
ON
Turn the servo on with the operation on the teaching
tool such as PC.
Check Item
Is the green light [SV] on
the LED status display on?
Pulse Train Mode Startup
Turn off the power to the controller.
Turn on the pulse train mode
changeover switch 1, and then turn
on the power to the controller.
Check Item
Is the orange light [ALM] on
the LED status display off?
Connect the teaching
tool such as PC to confirm
the content of alarm and
have an appropriate
treatment.
If an alarm is generated, connect
the PC or teaching pendant and
check the content of the alarm to
have the right treatment.
CAUTION
Please perform this process with the actuator away from the mechanical end or
interfering subjects as much as possible.
Put the actuator away if it interferes with surroundings. It may generate an alarm if the
actuator hit the mechanical end or interfering subjects when the servo is turned on.
The slider may get slightly dropped by self-weight if servo on and off is repeatedly
performed at the same position. Be careful not to pinch the hand or damage the work.
Safety Circuit Check
Does the emergency stop circuit (drive cutoff circuit) work properly and
turn the servo off?
Target Position Setting
Set the target position in “Position” Box in each position table.
Perform a home-return operation first when Direct Teaching is to be performed. When moving the
actuator manually, set the Brake Release Switch to “BK RLS” side for the brake equipped type.
Put the switch back after the setting is complete.
CAUTION
To ensure safety, it is recommended that safety speed be enabled during initial movements.
Check Item

abnormal noise?
Check Item
Use the force control
(function for CA Type only)?
Check the actuator if it is installed properly,
the condition for use is below the rated values,
etc.
Adjust the servo if necessary.
Initial Setting for Force Control
Perform the initial settings such as the loadcell
calibration on the teaching tool.
Test Run Adjustment 1
Check the operation without mounting
a work and set the safety speed invalid
on the teaching tool such as PC, and then
check the operation with a work mounted.
