8 CONTROL SUB FUNCTIONS
8.4 Functions to Limit the Control
Invalidating the software stroke limit
To invalidate the software stroke limit, set the following parameters as shown, and write them to the Simple Motion module.
(Set the value within the setting range.)
(To invalidate only the manual operation, set "1: software stroke limit invalid" in the "[Pr.15] Software stroke limit valid/invalid
setting".)
The set details are validated at the rising edge (OFF ON) of the PLC READY signal [Y0].
When the unit is "degree", the software stroke limit check is not performed during speed control (including speed control in
speed-position switching control or position-speed switching control) or during manual control, independently of the values set
in [Pr.12], [Pr.13] and [Pr.15].
• Parameters are set for each axis.
• It is recommended that the parameters be set whenever possible with the engineering tool. Execution by a
program uses many programs and devices. The execution becomes complicated, and the scan times will
increase.
Setting when the control unit is "degree"
■Current value address
The "[Md.20] Current feed value" address is a ring address between 0 and 359.99999.
■Setting the software stroke limit
The upper limit value/lower limit value of the software stroke limit is a value between 0 and 359.99999.
• Setting when the software stroke limit is to be validated.
When the software stroke limit is to be validated, set the upper limit value in a clockwise direction from the lower limit value.
Set as follows to set the movement range of section A or B in the above figure.
