Position the cam at the center of the axis. Traverse the cam at various axis
speeds and in the rapid traverse mode. Calculate the time and distance
traveled by the axis until the desired cam signal (NCK-SGA, PLC-SGA) is
output.
Locate the limit position/enstops at the center of the axis. Pass the position
at various axis speeds and in the rapid traverse mode. Calculate the
remaining distance traveled by the axis until it is stopped by the configured
stop response. Locate the safe limit in front of the fixed endstop of the axis
at a distance corresponding to the calculated remaining distance plus a
safety margin defined by the machine manufacturer.
