Influence on feed (P-CHAN-00066)

P-CHAN-00066	Influence of override on feed
Description	This parameter defines how feed is calculated in conjunction with path feed override. This means, for example, the parameter sets whether the override bandwidth is applied to the programmed feed or to the minimum programmed feed and the maximum permissible feed in the block (v_max). The CNC calculates the feed based on the permissible axis dynamics. The following velocities have an influence: v_max: Calculated maximum velocity of the CNC with no consideration given to reduced velocity v_red: Calculated reduced velocity of the CNC, taken from vb_max_red (P-AXIS-00214) of the axes v_prog: programmed velocity of the operator (F word) Value 0 for P-CHAN-00066: v = MIN (v_prog,v_max) * Override If this parameter is set to 0, a change of override always leads to a change of velocity in the machine (linear correlation). Value 1 for P-CHAN-00066: v = MIN (v_prog* Override, v_max) If this parameter is set to 1, the override always refers to the programmed feed. If the maximum feed in the block is smaller than the programmed feed multiplied by the current override, the current path feed is not changed when there is a change in override. Value 2 for P-CHAN-00066: Calculation is executed as for the value 0 provided there are no active functions that reduce velocity. For example, REDUCED_SPEED, REDUCED_SPEED_ZONE, IPO_ACTIVATE_TCP_VEL_LIMIT as for the value 1 provided there are no active functions that reduce velocity If velocity drops are not desired for technological reasons, this parameter must be set to 1.
Parameter	override_weight_prog_feed
Data type	UNS16
Data range	0: Change in override causes a change of velocity. 1: An override change only causes a velocity change if the programmed feed * override < maximum permissible velocity in the block 2: Override effect in conjunction with reduced velocity (available as of Build V3.1.3079.42)
Dimension	----
Default value	0
Remarks	Example of values: v_max: 50m/min v_prog: 80m/min v_red: 5m/min Override: 50% P-CHAN-00066=0 a) active reduced velocity v_set = 2.5m/min b) inactive reduced velocity v_set = 25m/min P-CHAN-00066=1 a) active reduced velocity v_set = 5m/min b) inactive reduced velocity v_set = 40m/min P-CHAN-00066=2 a) active reduced velocity v_set = 5m/min b) inactive reduced velocity v_set = 25m/min
