Selecting Active Pulse Edge and Control Signal Mode
The 3DM580 supports PUL/DIR and CW/CCW modes and pulse actives at rising or falling edge.
See more information about these settings in Section 13. Default setting is PUL/DIR mode and
rising edge active (NPN, and PNP control signal is on the contrary).

4. Control Signal Connector (P1) Interface
The 3DM580 can accept differential and single-ended inputs (including open-collector and PNP
output). The 3DM580 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.
