Software Limits

You can set limits in the software for machine movement that do not use the overtravel signals
(CCW-OT and CW-OT). If a software limit is exceeded, an emergency stop will be executed in
the same way as it is for overtravel.
You must make the following settings to use the software limits.
• You must enable the software limit function.
• You must set the software limits.
6.6.1

Setting to Enable/Disable Software Limits

You can use PnB18 (Software Limit Action Selection) to enable and disable the software limit
function.
The software limits are enabled at the following times:
• When an absolute encoder is used
• After completing an origin return when an incremental encoder is used
In all other cases, the software limit function will not operate even if a software limit is
exceeded.

Setting the Software Limit Action

You can use PnB18 (Software Limit Action Selection) to set the stopping method when a soft-
ware limit is exceeded.
When a software limit is reached, the target position is automatically replaced with the current
position.
