X1
– 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.
X1-X8: D-sub DA-15F
Mating: D-sub DA-15M

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.
