Isolated Input Interface and Connection

Optically Isolated Logic Inputs

The MDrivePlus Microstepping has three optically iso- lated inputs which are located at the flying leads or on connector P1. These inputs are iso- lated to minimize or eliminate electrical noise coupled onto the drive control signals. Each input is internally pulled- up to the level of the optocoupler supply and may be connected to sinking or +5 to +24 VDC

1] Step Clock (SCLK)/Quadrature (CH A)/Clock UP

2] Direction (DIR)/Quadrature (CH B)/ Clock DOWN

3] Enable (EN)

Of these inputs only step clock and direction are required to operate the MDrivePlus Microstepping.

Isolated Logic Input Pins and Connections

The following diagram illustrates the pins and connections for the MDrive 17 and 23 Plus Microstepping family of products. Careful attention should be paid to verify the connections on the model MDrivePlus Microstepping you are using.
