caution: If you position the tailstock manually, do not use an M21 in your program. This makes the tailstock move away from the workpiece and then against the workpiece, which may cause the workpiece to drop. When a servo tailstock restores hold force after a power interruption, the tailstock is considered manually positioned since the control does not know the tailstock position until you zero return it.

You cannot jog the ST-40 servo tailstock while it is engaged with a workpiece, or while the spindle is running.

To jog the tailstock:

  1. Select Jog mode.
  2. Press TS <— to jog the tailstock at feed speed toward the chuck, or press TS —> to jog the tailstock at feed speed away from the chuck.
  3. Press TS RAPID and TS <— simultaneously to move the tailstock at rapid speed toward the chuck. Or, press TS RAPID and TS —> simultaneously to move the tailstock at rapid speed away from the chuck. The control reverts to the last jogged axis when the keys are released.
