Error details and causes
Number of axes set for the master axis in servo
parameter "Driver communication setting (PD15)"
exceed the setting range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
Servo parameters "Driver communication setting
Master axis No. selection (1 to 4) for slave (PD20 to
PD23)" are set the self axis.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
Not setting the master axis in Servo parameters" Driver
communication setting Master axis No. selection (1 to
4) for slave (PD20 to PD23) ".
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
• Setting the driver communication to servo amplifier
which does not support the driver communication.
• The driver communication setting is different in the
module and the servo amplifier.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
Inter-module synchronization fault is detected.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
Inter-module synchronization fault is detected.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
Hardware is faulty.
[Operation status at error occurrence]
The system stops.
Hardware is faulty.
[Operation status at error occurrence]
The system stops.
Hardware is faulty.
[Operation status at error occurrence]
The system stops.
An error is detected in the CPU module.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/sudden stop) of the detailed
parameter 2 sudden stop selection (stop group 2). (Note
that the deceleration stop only occurs during the
manual pulse generator operation.)

Remedy
Set the number of master axis not more than the
number can be set in servo parameter "PD15".
Review the master axis No. of servo parameters
"PD20 to PD23".
Review the master axis No. of servo parameters
"PD20 to PD23".
• Confirm the driver communication and the actually
connected servo amplifier.
• After setting 'The driver communication setting',
write to a flash ROM and switch the power on again
or reset the PLC. After that turning the power of
servo amplifier on again, switch the power on again
or reset the PLC.
• Take measures against noise.
• After the Simple Motion module is reset, switch to
RUN. If the same error is displayed again, the
hardware fault might occur in the CPU module, base
unit, extension cable or Simple Motion module.
Please consult your sales representative.

Please consult your sales representative.
Check that there is no influence from noise.
Check that there is no influence from noise.
Replace the Simple Motion module.
Check the error of the CPU module and take corrective
action using the module diagnostics.
