Fig. 2-29 Definition of driver interface
Only 6 of the pins should be wired when connected with a stepping driver, and the 6 wires at one
end of DB15 provided by WEIHONG are distinguished by colors. You just need to connect the wires
according to the colors shown in the above picture.
+5V, GND: supplying 5VDC power to a stepping driver;
P+, P-: pulse (PULS), differential output signals;
D+, D-: direction (DIR), differential output signals.
2.3.2 Lambda 4S/5S Series Controller
Lambda 4S/5S series controller provides up to 5 pulse feed driver interfaces for X/Y/Z/the fourth/the
fifth axis. The 5 interfaces are 15-pin D-type sockets, and the pins definition is as shown in Fig. 2-30.
