Error
code
Error name Error details and cause Corrective action
1000H Power shutoff • A momentary power failure has occurred.
• The power supply has been shut off.
Check the power supply status.
1080H ROM write count error The number of writes to the flash ROM exceeded 100000
times. (Number of writes > 100000)
Replace the CPU module.
1200H Module moderate error A moderate error has been notified from the intelligent
function module connected.
Check the detailed information (system configuration
information), identify the error module, and eliminate the
error cause.
1210H Module moderate error An inter-module synchronous signal error has been
notified from the intelligent function module connected.
Check the detailed information (system configuration
information), identify the error module, and eliminate the
error cause.
1220H Another CPU module
moderate error
A moderate error has been notified from another CPU
module.
• Check the detailed information (system configuration
information), identify the error CPU module, and
eliminate the error cause.
• Check the mounting status and reset status of other
CPU modules.
1900H PLC ready OFF during
operation
"[Rq.1120] PLC ready flag" is OFF when operating. When all axes stopped, turn "[Rq.1120] PLC ready flag"
ON.
1901H Servo ready OFF "[St.1075] Servo ready" was OFF when starting.
• Servo amplifier power OFF
• In initial processing when the servo amplifier power is
ON
• Servo amplifier unimplemented
• Servo error occurred
• Cable faulty
• "[Rq.1155] Servo OFF command" is ON
Start when the "[St.1075] Servo ready" is ON.
1902H Servo ready OFF Servo amplifier power is OFF when controlling. (Servo not
mounted status detection, cable fault, etc.)
• Turn on the power supply of the servo amplifier. Or
check the connect cable to the servo amplifier.
• Execute gain adjustment.
1904H Hardware stroke limit + At a forward direction (address increasing direction) start,
the external signal FLS (upper limit switch signal) is OFF.
Perform the home position return after moving to the
proximity dog ON by the JOG operation, etc.
1905H Hardware stroke limit + At a forward direction (address increasing direction)
control, the external signal FLS (upper limit switch signal)
is OFF.
Perform the home position return after moving to the
proximity dog ON by the JOG operation, etc.
1906H Hardware stroke limit - At a reverse direction (Address decreasing direction) start,
the RLS external signal (Lower limit switch) is OFF.
Perform the home position return after moving to the
proximity dog ON by the JOG operation, etc.
1907H Hardware stroke limit - At a reverse direction (Address decreasing direction)
controlling, the RLS external signal (Lower limit switch) is
OFF.
Perform the home position return after moving to the
proximity dog ON by the JOG operation, etc.
1908H Stop signal ON • "[Rq.1140] Stop command" is ON when starting.
• "[Rq.1140] Stop command" is ON at the timing of home
position return.
• "[Rq.341] Command generation axis stop command" is
ON when starting.
• Turn OFF the "[Rq.1140] Stop command" and then start
it.
• "[Rq.1140] Stop command" and then perform the home
position return.
• Turn OFF the "[Rq.341] Command generation axis stop
command" and then start it.
1909H External stop signal ON • External stopping signal is ON when starting.
• External stopping signal is ON at the timing of the home
position return.
• Start as the external stop signal is OFF.
• Execute the home position return as the external stop
signal is OFF.
190BH Connect to unsupported
servo amplifier
Connect to unsupported servo amplifier and driver. Connect to supported servo amplifier and driver.
1927H Servo error detection
signal ON at start
The "[St.1068] Servo error detection" is ON when starting. Eliminate the servo error, reset the "[St.1068] Servo error
detection" by the "[Rq.1148] Servo error reset command",
then start operation.
192AH Start acceptance flag ON
at start
• The "[St.1040] Start acceptance flag" is ON when
starting.
• The "[St.345] Command generation axis starting
acceptance flag" is ON when starting.
• Start when the "[St.1040] Start acceptance flag" is OFF.
• Start when the "[St.345] Command generation axis start
acceptance flag" is OFF.
