Speed selection
With the "HWC Code Range", an HWC command range can be used as speed selection. For
this purpose, a speed (e.g. minimum assembly line speed) is assigned to a command
number; a higher speed (e.g. maximum assembly line speed) is assigned to a higher
command number. The speeds for all command numbers in−between are automatically
calculated by the control system.
Calculation of the variable speed (Vv) when using the "HWC Code Range":
HWC_min ...C0251/1
HWC_max ...C0251/2
Vv_min ...C0252/1
Vv_max ...C0252/2
HWC_act ...currently received HWC command
Vv = Vv_min + (HWC_act −HWC_min) * ((Vv_max −Vv_min) / (HWC_max −HWC_min))
Example:
HWC_min = 10
HWC_max = 190
Vv_min = 500 mm/min
Vv_max = 5000 mm/min
HWC_act = 11
Vv = 500 mm/min + (11 −10) * ((5000 mm/min −500 mm/min) / (190 −10))
Vv = 500 mm/min + 1 * 25 mm/min = 525 mm/min
