Hold error The "CPU error output mode setting" of module
parameter (network) is "Hold".
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/rapid stop) of the detailed parameter
2 Rapid stop selection (stop group 3). (Note that the
deceleration stop only occurs during the manual pulse
generator operation.)
Flash ROM write error • Data is not written to the flash ROM.
• Backup data saving is failure due to a drive error.
• The backup data is accessed externally.
[Operation status at error occurrence]
At start: The system does not operate.
Flash ROM sum check error • While data is written to the flash ROM, the power is
turned OFF.
• The backup data is corrupted.
[Operation status at error occurrence]
At start: The system does not operate.
Flash ROM sum check error • While data is written to the flash ROM in the
synchronous control area, the power is turned OFF.
• The backup data is corrupted.
[Operation status at error occurrence]
At start: The system does not operate.
Synchronous restoration data Synchronous restoration data reading is failure.
sum check error [Operation status at error occurrence]
The synchronous control initial value cannot be
restored.
Operation cycle time over The calculation process time of the positioning etc.
error exceeds the operation cycle.
[Operation status at error occurrence]
The operation continues.
Home position return request The home position return request flag is turned ON
ON when a fast-home position return is started (positioning
start No.9002).
[Operation status at error occurrence]
The fast-home position return does not start.
Home position return restart The restart command is turned ON after the machine
not possible home position return is stopped using a stop signal.
[Operation status at error occurrence]
The restart is not carried out.
ZCT read error The data is not loaded from the servo amplifier
properly upon the home position return.
[Operation status at error occurrence]
The home position return does not complete.
ABS reference point read • The data is not loaded from the servo amplifier
error properly upon the home position return.
• The in-position signal is not turned ON within 1.5
seconds after moving an axis to the home position.
[Operation status at error occurrence]
The home position return does not complete.
Home position return method Home position return is started with the home position
invalid return method which is not supported by the connected
device.
[Operation status at error occurrence]
The home position return does not start.
Outside JOG speed range At the time of JOG starting, the JOG speed comes out
of a specified range.
[Operation status at error occurrence]
The JOG operation is not carried out when the JOG
speed is outside the setting range at the time of JOG
start.
Inching movement amount The inching movement amount dose not satisfy the
error setting conditions
[Operation status at error occurrence]
Inching operation is not performed.

. (The setting value is large.)
Remedy
Change the setting of the module parameter
(network) "Output Mode upon CPU Error" to
"Clear".
Initialize the Motion module or write the
parameter again.
If the same error reappears, the flash ROM may
have reached the end of its writable life.
Reset the parameter and write it to a Flash ROM
again.
Reset the parameter and write it to a Flash ROM
again.
The internal memory (nonvolatile) is expected to
be at the end of its writable life. Exchange the
module.
Review the content of the positioning or change
the operation cycle setting longer than the
current setting.
Execute the machine home position return
(positioning start No.9001).
Start the machine home position return
(positioning start No.9001) again.
• Execute home position return again.
• Execute home position return again.
• Adjust the servo gain and in-position range,
and execute home position return again.
Correct to the available home position return
method.
Bring the JOG speed into the setting range.
Set a smaller inching movement amount so that
the setting condition is satisfied.
