8.12 Electronic gearing, Master-slave operation
It is possible to set up master/slave systems, use an external encoder as a command
encoder, secondary feedback device (dual loop control) or connect the amplifier to a third
party step controller. Depending on the signal voltage level connector X9 (5 V TTL) or X7 (24
V) must be used.
The WorkBench setup software is used for configuration. See the “Feedback 2” screen in
WorkBench for setup. FB2.SOURCE, FB2.MODE, FB2.ENCRES and others are used for
setting up an application with these interfaces.
Connector X9 can be configured as an input or as an output for 5 V (TTL level) signals.
