Timing at which the
completion signal turns ON

position
(6) Positioning band [mm]
What this setting means is different between “Positioning operation” and “Push-motion
operation.”
“Positioning operation”:
Define how far before the target position you want to turn the completion signal ON.
The factory setting is 0.1 mm.
For the positioning operation
(except for the solenoid valve mode below):
Increasing the value of positioning band quickens the
start of the next sequence operation, so the tact time
can be reduced. Set an optimal value by considering
the balance of the entire system.
For the positioning operation
(of the solenoid valve mode below):
Note that on PCON-C/CF/CA/CFA/CB/CFB, ACON-C/CA/CB, DCON-CA/CB, SCON-C/CA/CAL/CB,
ROBONET, ERC3 PIO Converter, RCP6S, MCON and MSCON (Remote I/O mode) controllers of
solenoid valve mode 2 or PCON-CY/CYB, ACON-CY/CYB, DCON-CYB controllers of solenoid valve
mode 1, set the band after which the completion signal turns ON. (same for Safety Category
Complied Type)
PCON-C/CF/CA/CFA/CB/CFB, ACON-C/CA/CB, DCON-CA/CB, SCON-C/CA/CAL/CB,
ROBONET, ERC3 PIO Converter, RCP6S, MCON and MSCON (Remote I/O mode) in
solenoid valve mode 2, PCON-CY/CYB, ACON-CY/CYB and DCON-CYB in solenoid valve
mode 1 (same for Safety Category Complied Type)
“Push-motion operation”:
Define the maximum push distance from the target position in push-motion operation.
Set an appropriate positioning band by considering the mechanical variation of the work part, by
making sure positioning will not complete before the actuator contacts the work part.
(Note) Depending on the combination with the actuator, PCON-CA/CFA/CB/CFB,
SCON-CA/CAL/CB and ERC3 may not be able to set a value smaller than the minimum
positioning width. (same for Safety Category Complied Type)
Position at which the load is contacted and completion of
push-motion operation is deemed complete and therefore
the completion signal turns ON
