Code Message Description
20C CSTR-ON during operation The start signal (CSTR) was turned ON by the PLC while the actuator
was moving. As a result, duplication of movement commands occurred.
20D STP-OFF during operation The hold signal (*STP) was turned OFF by the PLC while the actuator
was moving. As a result, the actuator stopped.
20E Soft limit over A soft limit was reached.
20F Missed work part in push-motion
operation The actuator missed the work part in push-motion operation.
Check the work part condition and review the target position/positioning
band settings.

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
309 Memory command denied
Write address error A command was denied in serial communication with the controller.
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] When RCP2 and ERC controllers are linked together via
SIO converters, not all link cables are connected although
24 V is supplied to all converters.
[4] The piano switches are set to the same number on multiple
controllers being linked.
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] Do not set the piano switches to the same number on
multiple linked controllers.
If the message persists, please contact IAI.
