Logic Interface and Connection

Optically Isolated Logic Inputs

The MDriveAC Plus Microstepping has three optically isolated logic inputs which are located on connector P1. These inputs are isolated to minimize or eliminate electrical noise coupled onto the drive control signals. Each input is internally pulled-up to the level of the optocou- pler supply and may be connected to sinking or +5 to +24 VDC sourcing outputs on a controller or

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 MDriveAC Plus Microstepping.

Isolated Logic Input Pins and Connections

The following diagram illustrates the pins and connections for the MDriveAC Plus Microstepping family of prod- ucts. Careful attention should be paid to verify the connections on the model MDriveAC Plus Microstepping you are using.
