Command Input Parameters
COMMAND INPUT DEVICE 3 – SAWTOOTH SENSOR
n
•
In Absolute Position mode, this parameter defines the position (in degrees)
required to produce a steer command of full left (Steer Command = -100%).
In Absolute Position mode, this parameter should be adjusted within the
range -180.0° – 180.0°.
In Relative Position mode, the parameter defines the number of turns
(in degrees) required to produce a steer command from center to full left
(Steer Command = -100%).
n
•
In Absolute Position mode, this parameter defines the position (in degrees)
required to produce a steer command of center position (Steer Command
= 0%). In Absolute Position mode, this parameter should be adjusted within
the range -180.0° – 180.0°.
In Relative Position mode, this parameter is not used.
n
•
In Absolute Position mode, this parameter defines the position (in degrees)
required to produce a steer command of full right (Steer Command = 100%).
In Absolute Position mode, this parameter should be adjusted within the
range -180.0° – 180.0°.
In Relative Position mode, the parameter defines the number of turns
(in degrees) required to produce a steer command from center to full right
(Steer Command = 100%).
n
•
Set this parameter to the minimum voltage of the sawtooth waveform.
Along with Max Volts and Tolerance, this parameter is used to fault-check
the sawtooth signals.
n
•
Set this parameter to the maximum voltage of the sawtooth waveform.
Along with Min Volts and Tolerance, this parameter is used to fault-check
the sawtooth signals.
n
•
Use this parameter to invert the signal to avoid physically swapping
the wires to pins 8 and 19.
n
•
The sensor is in absolute position mode when this parameter is set to On.
The sensor is in relative position mode when this parameter is set to Off.
Sets the minimum threshold for the Analog 1 and Analog 3 inputs
of the sawtooth sensor. If either the Analog 1 or Analog 3 voltage falls
below this threshold for 60 ms, a fault is issued.
Sets the maximum threshold for the Analog 1 and Analog 3 inputs
of the sawtooth sensor. If either the Analog 1 or Analog 3 voltage rises
above this threshold for 60 ms, a fault is issued.
The Analog 1 and Analog 3 voltages of the sawtooth sensor should always
be 0.5*(Max Volts - Min Volts) apart. A fault check is done by comparing
the two voltages and calculating the error. If the error is greater than the
Tolerance voltage for 60 ms, a fault is issued. This provides a second level
of fault detection and triggers a separate Sawtooth Command Sensor fault.
