PB_CMD_check_travel_limits 请问怎么用啊

#=============================================================
proc PB_CMD_check_travel_limits { } {
#=============================================================
#
# This custom command may be used to check for the maximum
# travel for each axis.  A warning will be output for each
# GOTO that exceeds the limits.  It does not check for
# parallel axis such as Z and W.  It does not account for
# any modifications done by the user to mom_pos before the
# coordinates are output.
#
#
# Import and call this command in PB_CMD_before_motion.
