Master/slave interface [X10]

The master/slave interface is bi-directional and can be configured with the FCT software as an input or
as an output for master/slave operation:
– Master (incremental encoder emulation): Output of tracking signals A/B/N of an incremental en-
coder for actuating a slave controller
– Slave (synchronisation): Input for tracking signals A/B, pulse/direction signals CLK/DIR or forward/
backward signals CW/CCW for synchronisation with a master controller.
