Optocoupler Reference
The MDriveAC Plus Microstepping Logic Inputs are optically isolated to prevent electrical noise being coupled into
the inputs and causing erratic operation.
There are two ways that the Optocoupler Reference will be connected depending whether the Inputs are to be
configured as sinking or sourcing.
Optocoupler Reference
Input Type Optocoupler Reference Connection
Sinking +5 to +24 VDC
