or busoff (communication stop
caused by data error being
repeated) is detected.
● Correct the node address, and then reboot the system.

nearby, or if the communication cable is laid parallel to a power line.
○ − −
Communication timeout
●
Confirm that the communication speed is set the same as the master setting.

Troubleshooting
The following alarm displays are frequently generated at the start-up operation. Take the measure referring to the following description.
When any of the other alarms is output, refer to the operation manual.
Status display Status contents Cause and Remedy
During emergency-stop It is not an alarm.
• It is generated when the emergency stop switch in the teaching
pendant or the personal computer application software is not
cancelled. In such case, cancel it.
• It is generated when the personal computer cable is not
connected to the emergency stop box.
• Check the emergency stop circuit.
Safety gate remains open.
Deadman switch OFF
It is not an alarm.
• It is generated when the system I/O ENB signal is opened.
Check the ENB signal. (It is generated when the safety gate is
open. Close the safety gate.)
• It is generated when the AUTO/MANU switch has been set to
“MANU” and the personal computer or the teaching pendant is
not connected. Connect the personal computer or the teaching
pendant or set the AUTO/MANU switch to “AUTO”.
• When the actuator is to be started up, hold the deadman switch
on the teaching pendant to turn it on.
AC Power Interruption
Momentary Power Failure
Power Voltage Drop
It is generated when the power voltage is not supplied. It will be
generated, for example, in the case that the 100VAC is supplied to
the controller with 200VAC specified. Check the power supply.
Absolute Data Backup Battery
Voltage Error
It will be generated in the case that the battery has not been
attached, or the battery voltage is dropped.
In the case of the actuator for the single-axis robots or Cartesian
robots with the absolute data specifications, it is generated when
the power is connected for the first time.
Perform the absolute reset.
Encoder Disconnection Error It is generated when the cable is broken or the encoder cable is not
connected to the controller. Check the wiring.
Encoder Reception Time Out It is generated when the encoder is broken, the cable is broken or
the encoder cable is not connected to the controller. Check the
wiring.
24V I/O error
DO output current error
It is generated when the +24V power for I/O is not supplied. Check
the power supply.
(How to start up the controller without connecting the I/O 24V power)
Set the I/O parameter No. 10 to No. 13 corresponding to the
standard or extended I/O board to “0”.
FieldBus Error It is generated when the field bus link connection is not established.
Check the link cable connection, I/O parameter and PLC parameter
settings.
(How to start up the controller without connecting the field bus)
Set the I/O parameter No. 10 to No. 13 corresponding to the
standard or extended I/O board to “0”.
RC Gateway Serious Breakdown
Error
When the RC gateway is used and an error occurs in the controller
connected SIO (serial communication), it is generated.
The following causes are possible.
• All effective RC axes are missing (not recognized).
→
A cable disconnection or broken wire is possible. Check the wiring.
• The power switch on the main CPU shows 0V.
→ Set the +5V power switch to right side (+5V supply side).
• The DPRAM access right can not be obtained for one hour or
more in the connected SIO.
→ Check the parameters for the X-SEL or RC controller.
•
A serious error such as a CPU error is caused in the connected SIO.
→ It is caused by the hardware breakdown. Contact IAI.

*1 For the single axis robots and Cartesian-type robots with absolute design and SCARA robots,
the homing operation is not required.
When the unit is set to Vertical and the servo
ON/OFF is repeated, it might descend slightly
due to its own weight. Therefore, be careful
not to catch your hand or damage the work.
•It is recommended to set the safety operation to Enable
for the first movement for safety purposes.
•When it is installed vertically and the brake release switch is set
to [RLS] side, it might descend due to its own weight. Therefore,
be careful not to catch your hand or damage the handle.
Has the motor cable connected?
Connect the motor cable.
Turn ON the servo motor with the personal
computer or teaching pendant operation.
Check on the monitor of the
PC or the teaching pendant
that the servo is ON.
Is the servo ON?
Set the parameters including I/O parameter with the personal
computer or teaching pendant operation.
If the communication is not established, set the I/O parameter
#18 to 0 to cancel the monitoring of the fieldbus error.
When the alarm is output, deal with it
after confirming the alarm description,
using the personal computer or teaching
pendant operation.
