(4) Setting method
(a) To specify the M code ON signal output timing for each positioning data
Use "[Da.27] M code ON signal output timing". The following shows the settings to use "[Da.27] M code ON
signal output timing".
• Set the M code No. in the positioning data "[Da.10] M code".
• Set the timing to output the M code ON signal [X4, X5, X6, X7] in the positioning data "[Da.27] M code ON
signal output timing".
(b) To set the same M code ON signal output timing for all positioning data
Setting "[Pr.18] M code ON signal output timing" enables batch specification of M code ON signal output timing
for each positioning data. Set 0 in "[Da.27] M code ON signal output timing" when using "[Pr.18] M code ON
signal output timing". When a value other than 0 is set, "[Da.27] M code ON signal output timing" will be valid.
(The setting in "[Pr.18] M code ON signal output timing" becomes valid on the rising edge (OFF to ON) of PLC
READY signal [Y0].)
The following shows the settings to use "[Pr.18] M code ON signal output timing".
• Set the M code No. in the positioning data "[Da.10] M code".
• Set "0: Use the set value in "[Pr.18] M code ON signal output timing"." (initial value) in the positioning data
"[Da.27] M code ON signal output timing".
• Set the timing to output the M code ON signal [X4, X5, X6, X7] in the detailed parameter "[Pr.18] M code ON
signal output timing".
