SINUSOIDAL OUTPUT PULSE OUTPUT SQUARE WAVE OUTPUT

SINUSOIDAL OUTPUT OPTION
CHAN A CHAN B This option provides quadrature sinusoids at the same spatial frequency (cycles/rev) as the line count on the disc. At lower line counts, the signals tend to be more trapezoidal
V REF BUFFERED SINUSOIDS P-P signal amplitude, data channels: 1.0 ± 0.1 V
360° ±180° INDEX INDEX(OPTIONAL) DATATRACK (OUT INTERP = B01 )The output device is an op amp referenced to (50% ±3%) x V. Amplitude ratio, min chan to max chan: .90 to 1.00 P-P signal amplitude, index channel: 0.7 ± 0.3 V.
V REF cc Typical signal values at 1 kHz with 4.7 k load to ground (20°C). All pulse outputs are direction-sensed (CW pulses and CCW pulses are on different terminals). The output device is an EIA/RS-422 balanced differential line driver protected to survive an extended-duration short circuit across its output. Pulse width is 0.4 ± 0.1 s. The index pulse is gated so that it always occurs simultaneously with a specific data pulse. The maximum output pulse rate is 650 kHz, based on maintaining adequate separation between pulses; however, the frequency response of the square waves from which the pulses are generated is often the limiting factor in determining maximum encoder speed. Available with either 5 V or 7-15 V encoder power input. PULSE OUTPUT OPTIONS

Pulses are at 1, 2, 4 or 8 times the line count on the disc. (OUT INTERP = P05 , P10 , or P20 )Available on Models 8235S only. QUADRATURE SQUARE WAVE OUTPUT OPTIONS 1x or 2x Square Waves Available on both models. Square waves are at the same or twice the spatial frequency (cycles/rev) as the disc line count.5x or 8x Square WavesAvailable on Model 8235S only. Square wave spatial frequency is five or eight times the disc line count.
