Alternatively there is a timing issue with the draw-bar cylinder and the arm movement. You may have to adjust the "timing drum" (small cylinder with slots milled into the surface)
If parameter related, the PC parameters (which are machine tool specific) may need some tweeking. Adjusting a timer to move the arm after the clamping is confirmed.
