PARAMETER RANGE DESCRIPTION
CAN Steer Center Offset -32768 – 32767
•
n
Defines the position (in counts) required to produce a steer
0x40E7 0x00 -32768–32767 command of center position (Steer Command = 0%). This allows a
service technician to recalibrate center without having to physically
adjust the sensor.
Note: This parameter is applicable only in absolute position mode.
CAN2 Steer Center Offset -32768 – 32767
•
n
Defines the position (in counts) required to produce a steer
0x40E6 0x00 -32768–32767 command2 of center position (Steer Command2 = 0%). This allows a
service technician to recalibrate center without having to physically
adjust the sensor.
Note: This parameter is applicable only in absolute position mode.
CAN Steer Left Stop to Center -32768 – 0
•
n
Defines the total CAN steer command sensor counts to produce a
0x40E8 0x00 -32768–0 steer command from the center position (Steer Command = 0%) to
the full left position (Steer Command = -100%). Left Stop to Center is
always a negative number.
CAN Steer Right Stop to Center 0 – 32767
•
n
Defines the total CAN steer command sensor counts to produce a
0x40E9 0x00 0 – 32767 steer command from the center position (Steer Command = 0%) to
the full right position (Steer Command = 100%). Right Stop to Center
is always a positive number.
CAN Steer Swap Direction On / Off
•
n
Changes the direction (left or right) of the CAN steer command input.
0x40EB 0x00 On / Off
CAN2 Steer Swap Direction On / Off
•
n
Changes the direction (left or right) of the CAN2 steer command
0x40EA 0x00 On / Off input.
Absolute Mode On / Off
•
n
The sensor is in absolute position mode when this parameter is set
0x40F0 0x00 On / Off to On.The sensor is in relative position mode when this parameter is
set to Off.

3 — PROGRAMMABLE PARAMETERS: Command Input Parameters
When setting up a steering command CAN device, for the system to be EN 13849
compliant, one PDO must be sent to the main processor and one to the supervisor.
For additional security, it is recommended that the PDO sent to the supervisor be the
opposite polarity and that Swap Direction be set for the supervisor only. Contact Curtis
technical support for help with setting up PDOs.
