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 controller and Leadshine driver.
