SINE+/COSINE+
Analog signal with nominal peak to peak amplitude of 0.8V. The output signal has a source impedance of 1K
Ω. This signal is only used to
align the sensor using an oscilloscope and is not suitable for feedback in a control system.
Output Signal Description
Output Signal Description
A+/A- Digital Quadrature output. Signal is a RS-422 compatible square wave.
Pulses are 90° out of phase with B+/B- outputs. Please see below.
