Major errors are caused by external input signals or by control commands from the
SCPU. The error codes for major errors are 1000 to 1999.
Major errors consist of control start-up errors, positioning errors, absolute system
errors, and system errors.
(1) Positioning control start-up errors (1000 to 1099)
The errors shown in this section are those detected when positioning control is
started.
Error codes, error causes, error processing and corrective actions are shown in
Table 2.8.
• The external stop signal of the
! ! ! ! !
corresponding axis was turned ON.
• When positioning was started in the forward
direction (addresses increasing), the
! ! ! ! !
external FLS (upper limit LS) signal was
turned OFF.
• When positioning was started in the reverse
direction (addresses decreasing), the
! ! ! ! !
external RLS (lower limit LS) signal was
turned OFF.
• When proximity type zeroing was started,
!
the external DOG (proximity dog) signal was
turned ON.
• The servo state of the corresponding axis is
not servo READY.
(M2415+20n: OFF).
(1) The power supply to the servo amplifier
is OFF.

(2) Initial processing is in progress after
turning on the servo amplifier.
(3) The servo amplifier has not been
installed.
(4) A servo error has occurred.
(5) Cable fault.
• The servo error detection signal of the
corresponding axis (M2408+20n) was
! ! ! ! !
turned ON.

Error
Corrective Action
• Turn OFF the STOP signal.
• Move the axis in the reverse direction in
the JOG mode until it enters the external
limit range.
• Move the axis in the forward direction in
the JOG mode until it enters the external
limit range.
• Move the axis to a point before the
proximity dog in the JOG mode and then
execute a zeroing.
• Wait until the servo status is READY
(M2415+20n: OFF).
• Eliminate the error at the servo side, reset
the servo error detection signal
(M3208+20n) by using the servo error reset
command (M2408+20n), then start
operation.
