Possible Master-Slave Configurations; Master Electrical Line Shaft From Encoder - gefran ADV200 User Manual

3.3 Possible master-slave configurations

The IPA 11394 Master Pos Source application parameter is used to select the source for the position
reference to which the slave axis is connected during operation in electrical line shaft mode.
The master position reference may come from an encoder or from the Fast Link communication interface.
3.3.1

Master electrical line shaft from encoder

In this case the master position reference comes from an encoder, which may be installed on a motor or
connected directly to the machine.
For the slave axis, the IPA 11394 Master Pos Source parameter must be set to "Encoder 2".
In configurations with at least 2 slave axes, it is possible for each slave axis to be the master position
reference for the next slave or to use the same master encoder for all the slaves.
An example of a configuration in which each slave axis acts as the master position reference for the next
slave is shown in the figure below.
Figure 3.3: Cascade repetition of encoders between slave axes
In this case, each slave axis needs an optional card with a double digital encoder input (type EXP-DE-
I2R1F2-ADV); the encoder emulation output of this card repeats the Encoder 1 input, i.e. the motor encoder
of the slave axis.
The figure below shows an example of configuration in which the master axis motor encoder is repeated to
all the slave axes.
