Tip Strip: Threshold for decremental throttle motor negative voltage after the throttle plate stops moving. (Negative)
Units: V
Detail: Indicates a threshold for decremental throttle motor negative voltage after the throttle plate stops moving.
When this decremental threshold is reached, the drive stops and transitions to the post calibration phase. This
parameter should be a negative value.
PsnCalOffset_ChX
Tip Strip: The amount that the signal must change before the motor voltage increment/decrement reaches the
specified threshold, terminating the calibration process for that direction. (Positive)
Units: V
Detail: The position calibration process tracks the primary position sensor signal as the throttle plate moves toward
the minimum and maximum positions. This offset is the amount that the signal must change before the motor
voltage increment/decrement reaches the specified threshold, terminating the calibration process for that direction.
Typically 0.005 V is adequate. If this parameter is 0, then the calibration process will push harder toward the
minimum/maximum positions. When this happens, the minimum and maximum positions can be difficult to achieve
during control, and cause the final output to the throttle motor to exceed the limit. This parameter should be a
positive value.
PsnCalDiff_Thresh_ChX
Tip Strip: Minimum threshold for the expected range of throttle plate travel. (Positive)
Units: V
Detail: At the completion of the position calibration process, the absolute value of the difference between the
maximum and minimum position sensor signal voltages is compared against this threshold. If it is less than the
threshold, then there was something wrong with the position calibration process because the throttle plate did not
move through the expected range of travel, or the position sensor is faulty. This fault is indicated by the Pos Cal Diff
Fault Boolean indicator within the Position Cal Out cluster.
