“0” — Setup for Pot input (see page 23)
Note: The steer motor should not respond to this command input because the
Interlock is Off. If the steer motor shows any movement (or if the Interlock is
On), stop and resolve the issue; see Preparation for commissioning, page 74.
a. Move the steer command pots to the Left position (not to the actual physi-
cal stop, but a small amount away, to allow for pot tolerance variation) and
observe the two voltages shown in the Monitor
» Command Input » Analog
Input
» Analog1 and Analog3 variables. Set the parameters Analog1 Left and
Analog3 Left to the observed voltages.
b. Move the steer command pots to the Center position and observe the two
voltages shown in the
Analog1 and Analog3 variables. Set the parameters Ana-
log1 Center and Analog3 Center to the observed voltages.
c. Move the steer command pots to the Right position (not to the actual physi
-
cal stop, but a small amount away, to allow for pot tolerance variation) and
observe the two voltages shown in the
Analog1 and Analog3 variables. Set the
parameters Analog1 Right and Analog3 Right to the observed voltages.
d. Set the four fault parameters (
Analog1 Fault Min, Analog1 Fault Max, Analog3 Fault
Min, and Analog3 Fault Max). Set these to voltages that will not be reached dur-
ing normal operation, but will be reached when the steer command inputs
become faulty (e.g., should there be an open or short circuit).
The Fault Min settings must be below the minimum voltage seen on
Analog1 or Analog3 when steered to the maximum left and right positions.
The Fault Max settings must be above the maximum voltage seen on
Analog1 or Analog3 when steered to the maximum left and right positions.
“1” — Setup for Encoder input (see page 25)
Note: The steer motor should not respond to this command input because the
Interlock is Off. If the steer motor shows any movement (or if the Interlock is
On), stop and resolve the issue; see Preparation for commissioning, page 74.
a. Both command encoders must move in the same direction and the values
must be positive for the Right direction and negative for the Left direction,
as defined on page 73. Observe the Monitor
» Command Input » Encoder
Input
» Encoder1 Counts and Encoder2 Counts variables. While moving the com-
mand encoders, verify that these values are both positive (for movements to
command Right steer direction) or negative (for movements to command
Left steer direction). If so, go on to Step “b”.
If one or both of the Encoder Counts is incorrect, use the parameters
Swap Encoder1 Direction and/or Swap Encoder2 Direction. Recheck the Encoder1
Counts and Encoder2 Counts variables and verify that they both move in the
same direction with the correct sign. If problems persist, contact your Curtis
customer support engineer before continuing.
