These errors occur by control command from the external input signal or Motion SFC
program, and the error codes 1000 to 1999 are used.
Major errors include the positioning control start errors, positioning control errors,
absolute position system errors and system errors.
(1) Positioning control start errors (1000 to 1099)
These errors are detected at the positioning control start.
The error codes, causes, processing and corrective actions are shown in Table
1.8.
Error cause
• The external STOP signal of
the applicable axis turned
on.
• The external signal FLS
(upper limit LS) turned off at
the forward direction
(address increase direction)
start.
• The external signal RLS
(lower limit LS) turned off at
the reverse direction
(address decrease direction)
start.
• The external DOG (proximity
dog) signal turned on at the
home position return start of
the proximity dog method.
• The applicable axis is not
servo READY state.
(M2415+20n: OFF).
(1) The power supply of the
servo amplifier is OFF.
(2) During initial processing
after turning on the servo
amplifier.
(3) The servo amplifier is not
mounted.
(4) A servo error is occurred.
(5) Cable fault.
(6) Servo OFF command
(M3215+20n) is ON.
• The servo error detection
signal of the applicable axis
(M2408+20n) turned on.

Corrective action
processing
• Turn the STOP signal off.
• Move in the reverse direction
by the JOG operation, etc. and
set within the external limit
range.
• Move in the forward direction
by the JOG operation, etc. and
set within the external limit
range.
• Perform the home position
return after move to the
proximity dog ON by the JOG
operation, etc. at the home
position return of the proximity
dog method.
Positioning
• Wait until the servo READY
control does

• Eliminate the servo error, reset
the servo error detection signal
(M2408+20n) by the servo
error reset command
(M3208+20n), then start
operation.
