In ST-40 model lathes, a servo motor positions the tailstock and applies hold force to the workpiece.

Change Setting 241 to control servo tailstock hold force. Use a value between 1000 and 4500 pounds-force (if Setting 9 is INCH) or 4450 and 20110 Newtons (if Setting 9 is MM).

Tailstock load and current hold force are displayed as the B Axis in the axis load display (in modes such as MDI and MEM). The bar graph indicates current load, and the red line indicates the maximum hold force value specified in Setting 241. Actual hold force is displayed next to the bar graph. In Jog mode, this display appears in the Active Tool pane.

A hold icon [3] displays whether or not the tailstock is engaged. Refer to page 5 for more information on the tailstock hold icon.
