6.2 Valid Rising Edge for Pulse Signal
The driver of the step-servo motor produced by Leadshine Technology Co., Ltd. is on
the valid rising edge. Some of its products can support the mode of valid rising/falling
edge. When these products are delivered out of the factory, they are all set at the valid
rising edge; if the user changes the ex-factory setting into the valid pulse falling edge,
Section 6.3 can be referred to for the wiring method. For the typical models such as M860
and 3MD560, Figure 6.2-1 and 6.2-2 show the wiring scheme of RD mainboard and
Leadshine driver.

6.3 Valid Falling Edge for Pulse Signal
The driver pulse ends of drivers for step-servo motors presently produced by most of
manufacturers are of valid falling edge. These companies include BERGER LAHR, Beijing
HollySyn Motor Technology Co., Ltd., Shenzhen YAKO Automation Technology Co., Ltd.,
Shenzhen Baishan Mechatronics Co., Ltd., Beijing Jektechnology Co., Ltd. and the like.
The input signals for some motor drivers are independent and some of common anode.
