Command Input Device 0 – 4

n
These two parameters determine which inputs will be used as the primary
0x4003 0x00 0 – 4 and supervisory user steer commands:
Supervision Input Device

n
0 = Pot input, where Analog 1 and Analog 3 inputs are connected
0x40E4 0x00 0 – 5 to two potentiometers as redundant inputs.
When an analog steering command is used, two channels
are required.
NAME PIN FUNCTION
Analog 1 8 Primary analog input command
Analog 3 19 Supervisory analog input command
It is best practice to wire the primary and supervisory input sig
-
nals in an “X” configuration (0–5V and 5V–0). However, the 1222
has independent maps and will support redundant signals that
move in the same direction.
1 = Encoder input, where Encoder 1 and Encoder 2 inputs are
connected to two quadrature encoders as redundant inputs.
When an encoder steering command is used, two quadra
-
ture encoders are required. In the table below, “+” and “-” indicate
encoder phase differences (“-” being some amount of phase shift
from “+”). This means that the primary and supervisory encoders
do not have to have the same alignment.
