Power Brick Controller User Manual

Connections and Software Setup

– X8: Encoder Feedback, Sinusoidal

The Power Brick Controller can process sinusoidal encoders (up to 1.2 V

peak-peak

), and provide high

resolution (x 16384) interpolated position data.

Caution

The +5 VDC encoder power is limited to ~250 mA per channel. For
encoders requiring more current, the +5 VDC power can be alternately
brought in externally through the +5 VDC ENC connector.

Caution

Encoders requiring a voltage level other than +5 VDC (higher or
lower) should be powered directly from an external power supply.
