1. Digital input circuit
M5-N series servo has 5 DI terminals in total. The DI common terminal can be connected to power supply or
ground, and supports dry contact input, NPN input and PNP input.
M5-N series servo does not provide 24 power supply to the outside, and the connection of DI uses external power
supply.
Take DI1 as an example, interface circuits of DI1-DI5 are the same.
(1) Dry contact mode
The dry contact wiring method is as shown in Fig. 4-3.
Fig.4-3 DI terminal dry contact connection mode
(2) NPN (drain) mode
The external controller is the NPN common emitter output, the wiring mode is as shown in Fig. 4-4.
