4.2 Digital I/O Details

4.2.1 Step & Direction/Master Encoder Inputs (P3, pins 1-4)

A master encoder with quadrature outputs or a step and direction pair of signals can be connected to the

PositionServo to control position in the external positioning operating mode. These inputs are optically

isolated from the rest of the drive circuits and from each other. Both inputs can operate from any voltage

source in the range of 5 to 24 VDC and do not require additional series resistors for normal operation.

Master Encoder Step & Direction Input Circuit

Differential signal inputs are preferred when using Step and Direction. Single ended inputs can be used but

are not recommended. Sinking or sourcing outputs may also be connected to these inputs. The function of

these inputs “Master Encoder” or “Step and Direction” is software selectable. Use the MotionView set up

program to choose the desirable function.
