Operating mode synchronous operation

The software module synchronous operation moves a slave axis in a synchronous angle
to a master axis.
A virtual master axis is calculated in the drive. The speed-set value must be specified.
The set value of the master axis serves as the input value for the electronic transmission.
The output value of the transmission is the position set value for the position control.
The following synchronous operation modes

Electronic transmission
The electronic transmission extends the functionality of the software module synchronous
operation with an adjustable transmission ratio between slave axis and master axis. The
transmission ratio i is specified from 2147483647:1 to 1: 2147483647 as quotient from
two natural numbers and can also be changed in the released status ("Online"). The
counter may become negative. The function of a reverse transmission can thereby be im-
plemented.

A position set value for the virtual master axis is calculated in the drive from the speed
set value. The drive follows this virtual master axis synchronized.
This mechanism is purposeful when other axis are connected as slave axis. These
slave axis then receive the set value of the virtual master axis as input set value. Sub-
sequently, all other axis then follow the same set value including the axis that calcu-
lates the virtual master axis itself.
The input set value of the virtual master axis can be routed through a ramp generator
(ramp function generator) or have a direct effect. Refer to the related explanations of
