(6) Invalidating the software stroke limit
To invalidate the software stroke limit, set the following parameters as shown, and write them to the LD75. (Set
the value within the setting range.)
[Pr.12] Software stroke limit upper limit value = [Pr.13] Software stroke limit lower limit value
To invalidate only the manual operation, set "0: software stroke limit invalid" in the "[Pr.15] Software stroke limit
valid/invalid setting".
The set data is made valid on the rising edge (OFF to 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].
Remark
● Parameters are set for each axis.
● It is recommended that the parameters be set whenever possible with GX Works2. Execution by program uses many
programs and devices. The execution becomes complicated, and the scan times will increase.
(7) Setting when the control unit is "degree"
(a) Current value address
The "[Md.20] Current feed value" address is a ring address between 0 and 359.99999.
(b) 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.
When the software stroke limit is to be validated, set the upper limit value in a clockwise direction from the
lower limit value.
• Set the movement range of section A as follows.
Software stroke limit lower limit value  315.00000
Software stroke limit upper limit value  90.00000
• Set the movement range of section B as follows.
Software stroke limit lower limit value  90.00000
Software stroke limit upper limit value  315.00000
