Shortcut SL Format SETLOW [axis]=[position in mm]… Units millimeter Type Axis-Specific Remembered Automatically
This command sets/displays the lower firmware limit for an axis. The limit is considered a fixed hardware locations and are adjusted properly when the controller’s coordinate system is altered with the HERE or ZERO commands. The limit positions are automatically remembered and recalled through a power cycle and do not need to be saved using the SAVESET command.
SL [axis]+ will set the lower limit to be the current position. Restore the default limit by executing SL [axis]-. The +/- operand syntax is supported as of Tiger firmware v2.8 and MS-2000 firmware as of roughly 2013.
The corresponding command for the lower firmware limit switch is the SETLOW command.

If there are no errors, a positive reply of :A followed by the startup sequence.
For the Z axis only, input values equal to or greater than the current SETUP parameter value are acknowledged by :A but ignored.
Example
SL X=-50 Y=-50 Z? :A Z=-110.000
In the above example, the lower limit for the X and Y axes have been set to 50 millimeters from the origin in the negative direction. Note that the Z? resulted in the controller returning the current position of the Z lower firmware limit switch.
Note 1: If this value is equal to or greater than the value for SETUP, then the controller will operate incorrectly. See also Note 2.
Note 2: When the direction of an axis is negative (see CCA Z=###), upper limit settings must be negative values, and lower limit settings must be positive values.
Note 3: For clocked devices (e.g. filter sliders, turrets) the lower limit is always 1.
