The 1771-ES PLC 5 Servo Encoder Feed-back Expander Module by AB is
a component of the Servo Positioning Assembly which provides
incremental digital encoder feedback, is located on the 1771 I/O
chassis, and requires 2 slots. It has -+10V DC isolated maximum
output voltage and uses a D/A Converter (DAC) with a 12-bit
(signed) resolution. It also has a Drive Disable Output with 100mA
source or sink current and 30V DC output voltage. The module draws
a maximum backplane current of 1.7A and has encoder input voltage
ratings of <1.6V DC (High) and >1V DC (Low). The 1mA sinking
encoder input has a user-selectable encoder rates (Differential at
250 kHz max, Single Ended: 20 kHz max) selectable using a jumper
selection which provides selection between the differential and
single-ended options. The 1771-ES encoder has 3 programmable
encoder multipliers (x1, x2, or x4), and its discrete input has
11.2k or 1.2k resistance selectable switch for each input.
It has a Trachometer input with full-scale 3V (min) and 50V (max)
and an input impedance of 20 Kilo Ohms. The 1771-ES has a maximum
programmable position of +-999.9999 inches (res 0.0001 in), with a
programmable speed range of 0.0001-9990 inches per minute (ipm) and
a maximum Acceleration/Deceleration of 9999ipm/s. It has an initial
gain of 0.01-9.99ipm/mil and a sample period time of 2.4ms. Keying
on the left 1771 I/O chassis slot is achieved by attaching the
connecting band between pins 2 and 4, 14 and 16, and on the right,
the I/O chassis is between pins 4 and 6, 32 and 34. The 1771-ES’s
operational temperature ranges between 32° and 140°F at 5-95%
non-condensing relative humidity limits and is kept between 40 and
185°F when non-operational.
