Normally, each tool offset has up to ten permanently allocated TO parameters. When required,
the user can upgrade the number of parameters to 32, and must allocate the added param-
eters (10 to 32) using the configuring terminal. The greater the number of TO parameters
allocated to a tool offset, the lower the number of tool offsets available to the user, as the
memory space available for tool offsets is limited.
