(2) Positioning control errors (1100 to 1199)
These errors are detected at the positioning control.
The error codes, causes, processing and corrective actions are shown in Table
1.9.

• The external signal FLS
(upper limit LS) turned off
during the forward direction
(address increase direction).
• Travel in the reverse direction
by the JOG operation, etc. and
set within the external limit
range.
1102
• The external signal RLS
(lower limit LS) turned off
during the reverse direction
(address decrease
direction).
• Travel in the forward direction
by the JOG operation, etc. and
set within the external limit
range.
1103
• The external STOP signal
(stop signal) turned on
during home position return
of proximity dog type.
Decelera-
tion stop by
"Stop
processing
on STOP
input" of the
parameter
block.
• 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 type.
1104
• The servo error detection
signal turned on during
positioning control.
Immediate
stop without
decelera-
ting.
• Start after disposal at the servo
error.
1105
• The power supply of the
servo amplifier turned off
during positioning control.
(Servo not installed status
detection, cable fault, etc.)
• Home position return did not
complete normally without
stop within the in-position
range of home position at
the home position return.
Turn the
servo
READY
(M2415+
20n) off.
• Turn on the power supply of the
servo amplifier.
• Check the connecting cable to
the servo amplifier.
• Make the gain adjustment.
• Q172EX or encoder
hardware error.
• Disconnected encoder cable.
Immediate
input stop
• Check (replace) the Q172EX or
encoder.
• Check the encoder cable.
1151
• A synchronous encoder set
in the system setting differs
from a synchronous
encoder actually connected.
• Q170ENC is connected to
Q172EX/Q172EX-S1.
Input from
synchro-
nous
encoder
does not
accept.
• Set a synchronous encoder
actually connected in the
system setting.
• Use Q172EX/Q172EX-S1 to
connect Q170ENC.
