[6] LoTh : ‚ In the case of a SCON-CA and PCON-CF controller, the load output signal (PI0) will be
output when the command torque exceeds the value set in the “LoTh” field (%) within
the certification range.
The certification range is set by “Zone+/-.”
Use this signal to determine if a press-fit operation has been successful.
* For details, refer to the operation manual for your PCON-CF controller.
[7] Positioning band : ‚ The “positioning operation” and “push operation” have different meanings.
Positioning operation:
It defines the distance to the target position from a position at which the position
complete signal turns ON.
The default value is 0.1 mm.
Standard type
Note that with a PCON-C/CG/CF, PCON-CA, CF ACON-C/CG, SCON, ERC3 PIO Converter or MSCON
(remote I/O mode) controller operating in solenoid mode 2 or PCON-CY or ACON-CY operating in solenoid
mode 1, you should define the band within which the complete signal will turn ON.
Push operation:
It defines the maximum push amount from the target position in the push operation.
Set the positioning band in such a way as to prevent positioning completion before the
actuator contacts work part by considering mechanical variations of work part.
(Note) For PCON-CA and ERC3, a smaller value than the minimum positioning band width
cannot be set.
Since increasing the positioning band value
hastens the next sequence operation, it
becomes a factor for cycle time reduction. Set
the optimum value by considering the balance
of the entire equipment.
