Invalidating the software stroke limit
To invalidate the software stroke limit, set a single value in both [Pr.12] Software stroke limit upper limit value and [Pr.13]
Software stroke limit lower limit value and write them to the RD75. (Set a value within the setting range.)
(To invalidate only the manual operation, set 0: Software stroke limit invalid in [Pr.15] Software stroke limit valid/invalid
setting.)
The settings are validated at the rising edge (when turned off and on) of PLC READY signal [Y0].
When the unit is degree, the software stroke limit check is not performed during the speed control (including the speed-
position switching control and position-speed switching control) or during the manual control regardless of the values set in
[Pr.12], [Pr.13], and [Pr.15].
• Parameters are set for each axis.
• Setting the parameters using an engineering tool is recommended. To perform the setting using programs,
many programs and devices are required. The execution becomes complicated, and the scan times will
increase.
