5.98.2 Operating mode 1: Coupling via cycles
In this operating mode, the FB couples the axes of the master drive and the slave drive via the set
feed constants and the cycles. One of the cycles of the master drive is mapped on one of the cycles
of the slave drive.
• In this type of coupling, both master measuring system and slave measuring system must be
modulo measuring systems.
• The C05092/1 and C05092/2 coupling factors do not have any effect in this operating mode.
• The speed ratio between the slave drive and the master drive is calculated according to follo-
wing formula:
[5-60] Formula for operating mode 1
• The conversion according to the formula above is remainder considered and hence drift-free
(consideration of remainders when performing divisions).
Application example: Printing roller
According to the formula above, the speed ratio between the master drive and the slave drive is cal-
culated as follows:
