2.2.3 Signal Explanation
1. The pulse movement code signals
XCP+, XCP-, YCP+, YCP-, ZCP+, ZCP-, 4CP+ and 4CP- are code pulse signals, XDIR+, XDIR-,
YDIR+, YDIR-, ZDIR+, ZDIR-, 4DIR+ and 4DIR- are movement direction signal, and the signals of
two groups are difference output.
The circuit diagram is shown as below:

2. The drive unit alarm signal ALM (input)
The receive method of this signal at the system side is shown below. Whether the high level or
