These messages are displayed to confirm operation.
(They do not indicate an operation error or other abnormality.)
201 Emergency Stop An emergency stop condition was detected. (This is not an error.)
It is displayed for PCON, ACON and SCON.
- Emergency Stop This message indicates an emergency stop condition. (This is not an error.)
It is displayed for PCON, ACON and SCON.
- Motor voltage drop This message indicates the motor drive power shut-off condition due to an open circuit
between the MPI terminal and MPO terminal.
(Note) If this message occurs when a circuit between the MPI terminal and MPO
terminal is closed, a controller failure is suspected.
- ABS battery voltage drop This message indicates that the battery voltage dropped when the power was turned
ON.
20A During movement, Servo OFF This message indicates that the servo ON signal (SON) was turned OFF by the PLC
while the actuator was moving and that the servo turned OFF and the movement was
disabled as a result.
20C During movement, CSTR-ON This message indicates that the start signal (CSTR) became “1” by the PLC while the
actuator was moving and that duplicate movement commands occurred as a result.
20D During movement, STP-OFF This message indicates that the temporary stop signal (*STP) was turned OFF by the
PLC while the actuator was moving and the movement was disabled as a result.
20E Soft limit over This message indicates that a soft limit was reached.
210 HOME-ON during operation This message indicates that a home return signal (HOME) became ON from PLC and
duplicate movement commands occurred during movement operation.
211 JOG-ON during operation This message indicates that a home return signal (HOME) became ON from PLC and
duplicate movement commands occurred during movement operation.
220 Write in AUTO prohibited This messages indicates that parameter writing operation was performed in the AUTO
mode of the PCON-C/CG, ACON-C/CG, or SCON controller.
221 Write in Monitor mode
prohibited
This message indicates that position data or parameter writing operation was performed
in the Monitor mode.
222 Operation in AUTO prohibited This message indicates that actuator movement operation was performed in the AUTO
mode.
223 Operation in Monitor mode
prohibited
This message indicates that actuator movement operation was performed in the Monitor

These messages indicate an error in the serial communication with the controller.
Cause: [1] Garbage data due to the effect of noise
[2] Duplicate slave numbers when multiple controllers are controlled by serial
communication.
Action: [1] Adjust the wiring in a manner eliminating the effect of noise and review the
installation of equipment, etc.
[2] Change the slave numbers to avoid duplication.
If the message is still displayed after taking the above actions, please contact IAI.
