position
(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 and ROBONET 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, ACON-C/CG, SCON-C, SCON-CA, ROBONET and ERC3 PIO converter controllers
of 3-point type or PCON-CY and ACON-CY controllers of proximity switch type, set the band after which
the completion signal turns ON.
PCON-C/CG, ACON-C/CG and SCON-C, SCON-CA, ROBONET and ERC3 PIO converter 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 load, by making sure
positioning will not complete before the actuator contacts the load.
Position at which the load is contacted and completion of
push-motion operation is deemed complete and therefore
the completion signal turns ON
