4. Control Signal Connector Interface
The MC860H can accept differential and single-ended inputs (including open-collector
and PNP output). The MC860H has 3 optically isolated logic inputs which are located on
connector P1 to accept line driver control signals. These inputs are isolated to minimize
or eliminate electrical noises coupled onto the drive control signals. Recommend use line
driver control signals to increase noise immunity of the driver in interference
environments. In the following figures, connections to open-collector and PNP signals are
illustrated.

◆ Typical Connection
A complete stepping system should include stepping motor, stepping driver, power
supply and controller (pulse generator). A typical connection is shown as figure 4.
