Since, when using the spindle speed output in code, the spindle- and feed ramps cannot be<br />

synchronized by the NC, a machine parameter MP7120.1 was introduced to enable the spindle to be<br />

switched off early. M05 is automatically output by the NC and must be acknowledged.<br />

The machine parameter MP7120.0 (dwell time for change of direction of rotation) and the<br />

programmable dwell time are just as effective as for analog spindle-speed output.<br />

MP7120.1 Advanced switch time of spindle for "tapping" cycle (only active with BCD output<br />

of spindle rpm)<br />
