IMM PGM MIP
USAGE ♦ ♦ ♦
SYNTAX xxSLnn or xxSL?
PARAMETERS
Description xx [ int ] - axis number
nn [float] - left (negative) software limit
Range xx - 1 to MAX AXES
nn - -2e9 ∗ encoder resolution to 0
Units xx - none
nn - predefined motion units
Defaults xx missing: error 37, AXIS NUMBER MISSING
out of range: error 9, AXIS NUMBER OUT OF RANGE
nn missing: error 38, COMMAND PARAMETER MISSING
out of range: error xx2, PARAMETER OUT OF RANGE
DESCRIPTION This command defines the value for the negative (left) software travel limit. It
should be used to restrict travel in the negative direction to protect the motion
device or its load. For instance, if traveling full range, a stage could push its load
into an obstacle. To prevent this, the user can reduce the allowed travel by
changing the software travel limit.
Since a motion device must be allowed to find its home position, the home switch and/or
sensor must be inside the travel limits. This means that both positive and negative travel
limits cannot be set on the same side of the home position. A more obvious restriction is
that the negative limit cannot be greater than the positive limit. If any of these restrictions
is not respected, the controller will return PARAMETER OUT OF RANGE.
Note:
If the command is issued for an axis in motion, the new limit should not be set
inside the current travel.
Note:
For software units to take effect they must be enabled using the ZS command.
CAUTION
Be careful when using this command. The controller does not know the real
hardware limits of the motion device. Always set the software limits inside the
hardware limits (limit switches). In normal operation, a motion device
should never hit a limit switch.
RETURNS If the “?” sign takes the place of nn value, this command reports the current setting
REL. COMMANDS OR - search for home
SR - set right software limits
EXAMPLE 1SL41.4 | set negative travel limit of axis #1 to 41.4 units
