5.98.1 Operating mode 0: Coupling via feed constants
In this operating mode, the FB couples the axes of the master drive and the slave drive via the set
feed constants. The cycles of the master measuring system and the slave measuring system do not
have any effect.
• Via C05092/1 and C05092/2 the ratio of the corresponding units is set, i.e. how many units of
the master axis (x axis) correspond to how many units of the slave axis (y axis).
• The speed ratio between the slave drive and the master drive is calculated according to follo-
wing formula:
[5-59] Formula for operating mode 0
• The conversion according to the formula above is remainder considered and hence drift-free
(consideration of remainders when performing divisions).
Application example: Synchronous conveying belts
According to the formula above, the speed ratio between the master drive and the slave drive is cal-
culated as follows:
