Special attention:
lf the pulse command signal is a 24V power supply, PULS+must be connected to pin 39 of CN1, andSlGN+must be connected to pin 38 of CN1, otherwise it may damage the pulse command port;
lf the pulse commandsignal is a 5V power supply, PULS+must be connected to pin 25 of cN1, and SiGN+must be connected to pin 24 of CN1.otherwisethere may be abnormal pulse reception;
