Wheel Position Feedback Encoder Input
Encoder 1A, 1B (pins J3-2, J3-9)
ese inputs are the signal inputs for the Steer Motor Encoder.
Encoder 2A, 2B (pins J2-5, J2-6)
ese are the signal inputs for the redundant Steered Motor Encoder.
Input current (to Encoder Ground) 1.5 mA ± 20%
Input lter R-C time constant 1 μs
Max LOW threshold voltage 1 V
Min HIGH threshold voltage 4 V
Wheel Position Feedback Analog Input
To sense the position of the steered wheel a single or dual 5 Kohm position feedback potentiometer
has to be used.
Position Analog 1 and Redundant position analog 2 (pins J3-2, J3-9)
ese are the inputs to the controller wiper(s) of the position feedback potentiometer.
Input resistance (to B- ground) 50 kΩ ± 10%
Input current (wheel in center position) max 100 μA ± 10%
Input lter R-C time constant max 5 ms
Voltage range 0 – 5.5 V
Minimum resolution 12 bit
+5V Supplies (pin J3-7, J3-11)
Independent power supply connections to the Command Input Device and the Position Feedback Device.
The current draw on this supply is measured and can be used to detect the disconnected fault of
the command/position sensor power supply wires by the 5V Supply 1/2 Current Min parameters.
See page 27.
Command supply voltage +5 V ± 10%
Maximum current draw 100 mA (per pin)
Current measurement range 5 – 100mA
+12V Supply (pin J1-4)
is pin is the power supply for programmers and 840 displays
Command supply voltage +12 V ± 10%
Maximum current draw 100 mA
