If two or more PCMM networks have to follow the same position set point, it's possible to use the following strategy.
The image below shows a typical configuration where all the AKD drives must follow the same position set point:
Orange connection is a physical pin-to-pin cable between X9 ports (encoder like wiring).
The strategy consists to declare one MASTER within the PCMM 1 program and sent its output to X9 port of one AKD (like an encoder emulation), e.g. the AKD 1_3.
