4.3 TROUBLESHOOTING WITHOUT ALARM CODES (Cent’d)
4.3.14 SKIP FUNCTION (G31 ) OPERATION FAILURE
Table 4.43 Skip Function (G31) Operation Failure
Cause of Trouble
Input failure of skip
signal
Model JANCD-FC230B
or
FC260 board is
wrong.
Parameter not set
correctly
Check Method
Jse 1/0 signal #3514 D
o to D 2 to confirm the
kip signal ON/OFF.

TOE-C843-11.5).
‘arameter pm2001 DO
D 41: Use a transmission speed shown at th[
skip function (G31) command time as
a speed set to parameter pm2440.
O: Use a transmission speed shown at
th[
skip function (G31) command time as
a speed assigned by the F code.
~or example, the machine does not work
vhen the transmission speed is O at the
)arameter pm2440 G31 command time.
‘arameter pm5011 DO to DZ
let a
signal mode shown at the start time of
he “SKIP” input for the D
o skip function,
@ : When this parameter is set to “O”,
start the operation at the time of
change from 24 V to O V.
@: When this parameter is set to “ I”,
start the operation at the time of
change from O V to 24 V.
9 When this parameter is changed, turn
power on, then off again.
Parameter
pm5010 DO to D2
Determine ENABLE/DISABLE of an input
control circuit of “SKIP” for the skip
function.
~ 1. When h
t e skip function is used, set
the bit to “l”.
2. When this parameter
1s changed,
turn power on, then off again.
Solution
Confirm operation of the
contactless switches, etc.
Replace model
JANCD-
FC230B or FC260 board.
