Optocoupler Reference

The Microstepping MForce PowerDrive 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

Sourcing Controller Ground

Table 2.4.2: Optocoupler Reference Connection

NOTE: When

connecting the

Optocoupler Supply,

it is recommended

that you do not use MForce

Power Ground as Ground

as this will defeat the optical

isolation.
