Absolute Mode = Off is for relative position mode. The sensor input is
typically a multi-turn device with the center position being wherever the sen
-
sor is positioned when the interlock is turned on. Relative position mode is
typically used for reach trucks and man-up material handling applications.
b. For Absolute Position Mode (Absolute Mode = On):
1. Move the CAN Sensor to the center position and observe the counts
shown in the Monitor
» Command Input » CAN Input » CAN Steer Com-
mand variable. Set the CAN Steer Center Offset to the observed counts.
2. With the CAN Sensor still in the center position, observe the counts
shown in the Monitor
» Command Input » CAN Input » CAN2 Steer Com-
mand variable. Set the CAN2 Steer Center Offset to the observed counts.
3. Move the CAN Sensor to the Left position (not to the actual physical
stop, but a small amount away, to allow for sensor tolerance variation)
and observe the counts shown in the Monitor » Command Input » CAN
Input
» CAN Steer Counts and CAN2 Steer Counts variables. The observed
CAN Steer Counts and CAN2 Steer Counts must both be negative. Change
the CAN Steer Swap Direction and CAN2 Steer Swap Direction as necessary to
achieve negative count values for the
CAN Steer Counts and CAN2 Steer
Counts variables. If changes were made to either of the swap param-
eters, return to the beginning of Step “b” to reset the
CAN Steer Center
Offset and CAN2 Steer Center Offset parameters. Set the CAN Steer Left Stop
parameter to the observed count.
4. Move the CAN Sensor to the Right position (not to the actual physical
stop, but a small amount away, to allow for sensor tolerance variation)
and observe the counts shown in the Monitor
» Command Input » CAN
Input
» CAN Steer Counts and CAN2 Steer Counts variables. Set the CAN
Steer Right to Center parameter to the observed count.
c. For Relative Position Mode (Absolute Mode = Off):
1. Set the
CAN Steer Center Offset and CAN2 Steer Center Offset to zero, as
these parameters are not used in relative position mode.
2. Set the
CAN Steer Left Stop to Center parameter to the number of nega-
tive counts required to produce a steer command from center to full
left.
3. Set the
CAN Steer Right Stop to Center parameter to the number of counts
required to produce a steer command from center to full right.
4. Verify that turning the CAN sensor to the left results in negative
counts for both the
CAN Steer Counts and the CAN2 Steer Counts vari-
ables. Change the
CAN Steer Swap Direction and CAN2 Steer Swap Direction
as necessary to achieve negative count values for both the
CAN Steer
Counts and the CAN2 Steer Counts variables.
“5” — None. No Supervisory Steer Command Input Device (see page 22)
is option is available only for the Supervision Input Device parameter, and
allows systems with a single steer command device to be set up without having
