SL
Description
Negative software travel limit set.
Syntax
xx SL nn
Remarks
This command is used to set the negative software travel limit for an axis. If this command is
issued when an axis’ absolute position search is in progress, the controller will generate
“COMMAND NOT ALLOWED DURING HOMING” error message. The controller will
generate “PARAMETER OUT OF RANGE” error message if the value specified is greater
than the positive software travel limit. This value can be saved in controller’s non-volatile
memory by issuing “SM” command. If define home (DH) command is issued after this
command is issued, the controller will adjust the software travel limits and temporarily override
the value specified using this command. The temporarily modified software limits are not
saved in controller’s non-volatile memory. This allows the controller to preserve user-specified
software limits. Bit #3 in hardware configuration register (refer ZH command) must be set to 1
in order for the controller to check for any software travel limit violations.
Argument Value Description
xx 1 to 2 Axis number
nn Integer Negative software travel limit (encoder counts)
Example
1SL-8250 (set axis 1 negative travel limit to -8250 encoder counts)
1SR8190 (set axis 1 positive travel limit to 8190 encoder counts)
SM (save to non-volatile memory)
