Power Brick Controller User Manual
Connections and Software Setup

The Power Brick Controller can accept “sine” and “cosine”
signals (90° out of phase with each other), of 1-volt (peak-
to-peak) magnitude. Due to their inherit susceptibility to
electrical noise, these signals are most commonly
differential pairs, wired into the SIN+, SIN-, COS+, and
COS- inputs for the channel. Differential signals can
enhance immunity by providing common mode noise
rejection. Single-ended inputs can also be used, wired into
the SIN+ and COS+ inputs for the channel, with the SIN-
and COS- inputs connected directly to the 2.5V reference
(pin #7).
A good quality shielded cable with twisted-pair shielded
conduits is highly recommended for sinusoidal encoder
applications.
Configuring Sinusoidal Encoders
The sinusoidal encoder signals are interpolated in the ASIC (hardware); the resulting data is brought into
the encoder conversion table (ECT) as a single 32-bit word without any scaling:
The Arctangent calculation must be enabled for this channel. The encoder type for this motor must be set
for a DSPGate3 arctan extension. Activating the channel, should then be sufficient to display counts in the
position window when the motor/encoder shaft is moved by hand.
