SWLS.LIMIT0

Description

This parameter sets the compare register for the software limit switch 0. This value can be either the lower or the upper software limit switch register, depending on the configuration of the software limit switches:

  • If only one limit switch is enabled (SWLS.EN = 1 or 2), then SWLS.LIMIT0 is the lower limit, and SWLS.LIMIT1 is the upper limit.
  • If both limit switches are enabled (SWLS.EN = 3), then whichever switch is set to a larger value is the upper limit switch. The other switch becomes the lower limit switch.

These switches can be used in addition to hardware limit switches. The software limit switches are only active if the axis is homed. For more information about homing, please refer to the HOME Parameters and DRV.MOTIONSTAT.
