Chapter 3 Kinetix 300 Drive Connector Data and Feature Descriptions
Master Gearing/Step and Direction Inputs
You can connect a master encoder with quadrature outputs to the Kinetix 300
drive and control position in the Master Gearing operating mode.
You can connect a step and direction signal pair to the Kinetix 300 drive and
control position in the Step and Direction 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…24V DC and do not require additional series resistors for normal operation.

Differential signal inputs are preferred when using master gearing/step and
direction. When using differential signal inputs, sinking or sourcing outputs can
IMPORTANT Master gearing inputs must be incremental encoders with TTL outputs.
