PARAMETER RANGE DESCRIPTION
Left Angle (deg) -1800.0° – 0.0°
•
n
In Absolute Position mode, this parameter defines the position (in degrees)
0x40CC 0x00 -20480–0 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%).
Center Angle (deg) -180.0° – 180.0°
•
n
In Absolute Position mode, this parameter defines the position (in degrees)
0x40D2 0x00 -2048–2047 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
.
Right Angle (deg) 0.0° – 1800.0°
•
n
In Absolute Position mode, this parameter defines the position (in degrees)
0x40CD 0x00 0–20479 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%)
.
Min Volts 0 – 10.00 V
•
n
Set this parameter to the minimum voltage of the sawtooth waveform.
0x40EC 0x00 0 – 1023 Along with Max Volts and Tolerance, this parameter is used to fault-check
the sawtooth signals.
Max Volts 0 – 10.00 V
•
n
Set this parameter to the maximum voltage of the sawtooth waveform.
0x40ED 0x00 0 – 1023 Along with Min Volts and Tolerance, this parameter is used to fault-check
the sawtooth signals.
Swap Direction On / Off
•
n
Use this parameter to invert the signal to avoid physically swapping
0x406A 0x00 On / Off the wires to pins 8 and 19.
Absolute Mode On / Off
•
n
The sensor is in absolute position mode when this parameter is set to On.
0x40F0 0x00 On / Off The sensor is in relative position mode when this parameter is set to Off.
Fault Min 0 – 10.00 V Sets the minimum threshold for the Analog 1 and Analog 3 inputs
0x400B 0x00 0 – 1023 of the sawtooth sensor. If either the Analog 1 or Analog 3 voltage falls
below this threshold for 60 ms, a fault is issued.
Fault Max 0 – 10.00 V Sets the maximum threshold for the Analog 1 and Analog 3 inputs
0x400C 0x00 0 – 1023 of the sawtooth sensor. If either the Analog 1 or Analog 3 voltage rises
above this threshold for 60 ms, a fault is issued.
Tolerance 0 – 10.00 V The Analog 1 and Analog 3 voltages of the sawtooth sensor should always
0x40DF 0x00 0 – 1023 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.
