Description

Syntax
This command is used to set the positive 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 lower than
the negative 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.
