(5) Push
Select "Positioning operation" or "Push-motion operation."
The factory setting is 0.
0 : Normal positioning operation
Other than 0 : A current limiting value is indicated, meaning that this is a push-motion operation.
Caution: With PCON, ACON, SCON-C, SCON-CA, ERC2, ERC3, ROBONET and MSCON
controllers, the value entered in the "Push" field may be rounded to a multiple of the
controller's minimum resolution.
(When data is acquired from the controller)
(6) Positioning band
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.
Standard type
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.
Note that on PCON-C/CG/CF, PCON-CA, ACON-C/CG, SCON-C, SCON-CA, ROBONET, ERC3 PIO Converter
and MSCON (Remote I/O mode) controllers of solenoid valve mode 1 or PCON-CY and ACON-CY controllers of
solenoid valve mode 1, set the band after which the completion signal turns ON.
PCON-C/CG/CF, PCON-CA, ACON-C/CG, SCON-C, SCON-CA, ROBONET, ERC3 PIO Converter
and MSCON (Remote I/O mode) in solenoid valve mode 2, PCON-CY, or ACON-CY in solenoid
valve mode 1
"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) For PCON-CA and ERC3, a smaller value than the minimum positioning band width cannot be set.
Position at which the load is contacted and completion of
push-motion operation is deemed complete and therefore
the completion signal turns ON
