Code Message Description
20C CSTR-ON during movement The start signal (CSTR) was turned ON from the PLC while the actuator was
moving, resulting in redundant move commands.
20D STOP-OFF during
movement
The pause signal (*STP) was turned OFF from the PLC while the actuator was
moving, disabling the actuator movement.
20E Soft limit over A soft limit was reached.
20F Missed work detected The actuator passed the work without contacting it in push-motion operation.
Review the work condition as well as the target position/positioning band
settings.
210 HOME-ON during movement The homing signal (HOME) was turned ON from the PLC while the actuator
was moving, resulting in redundant move commands.
211 JOG-ON during movement The jog signal (JOG) was turned ON from the PLC while the actuator was
moving, resulting in redundant move commands.

Packet R-QUE OV
Packet S-QUE OV An error occurred in serial communication with the controller.
Cause:
[1] Garbage data due to noise
[2] Duplicate slave numbers when multiple actuators are controlled
via serial communication
Action: [1] Revise the wiring, equipment layout, etc., to eliminate noise.
[2] Change the slave numbers to eliminate duplication.
If the message persists, please contact IAI.
307 Memory command denied A command was denied in serial communication with the controller.
309 Write address error An indeterminable write address error occurred in serial communication with
the controller.
These messages do not generate during normal operation. Should either of
them occur, record the entire error list before turning off the power. The
recorded error list will help us identify the cause of the problem.
Also contact IAI.
30C No connected axis The controller axis number cannot be recognized.
Cause:
[1] The controller is not operating properly.
[2] Only the communication line of the supplied cable (SGA/SGB) is
open.
[3] If the SIO converter is used, the link cable is not connected
although the converter is receiving 24 V.
[4] When multiple controllers are linked, the ADRS switch is set to
the same number by mistake on two or more controllers.
Action: [1] Check if the RDY LED on the controller is lit. If this LED is not lit,
the controller is faulty.
[2] If you have a spare teaching pendant, change to the spare
teaching pendant. Or, switch to the PC software mode and see if
the message will disappear.
[3] Connect all pairs of converter and controller using link cables,
and then supply the power.
[4] Set each ADRS switch to a unique number.
If the message persists, please contact IAI.
