Dynamic spindle speed monitoring

Available as of V3.1.3125.0

Normally, the speed of a spindle is monitored by a simple tolerance band (P-AXIS-00217). If the speed reaches the tolerance limit, the state signal “Speed-value attained” is set.

In special cases, the simple tolerance band using kenngr.vb_prozent (P-AXIS-00217) is not sufficient for speed monitoring.

This may be the case, for example, when a spindle is operated at many different speeds. Dynamic speed monitoring makes it possible to specify a tolerance band for 2 different speeds. The tolerance band is then interpolated linearly between the two speeds. The parameterised value applies outside the two speeds.

P-AXIS-00838 (vb_prozent_dyn_dz) acts at speeds greater than P-AXIS-00840 (vb_upper) and P-AXIS-00217 (vb_prozent) acts at the value parameterised in P-AXIS-00839 (vb_lower) and below.

If no speed parameter is entered, dynamic speed monitoring is disabled and P-AXIS-00217 (vb_prozent) takes effect.

Dynamic speed monitoring is enabled by parameterising P-AXIS-00840 (vb_upper). At least one of the two parameters must be assigned to the tolerance band (vb_prozent / vb_prozent_dyn_dz).

P-AXIS-00839 (vb_lower) must be smaller than P-AXIS-00840 (vb_upper).
