PARAMETER RANGE DESCRIPTION
5V Current Min 0 – 100 mA Defines the lower threshold of the output current of the +5V supply
0x4096 0x00 0 – 1000 (pins 21 and 34). At or below this threshold, a fault is issued.
5V Current Max 0 – 100 mA Defines the upper threshold of the output current of the +5V supply
0x4097 0x00 0 – 1000 (pins 21 and 34). At or above this threshold, a fault is issued.
Steer Command Tolerance (deg) 2.0° – 90.0° Defines the maximum difference allowed between the two steer
0x40AA 0x00 364 – 16380 command inputs (Steer Command and Steer Command 2).
If the programmed tolerance is exceeded, a fault is issued.
The difference between the two steer command inputs can be
seen in the monitor variable Steer Command Error.
A setting of 90.0° turns off this fault check.
Wheel Position Tolerance (deg) 2.0° – 90.0° Defines the maximum difference allowed between the two position
0x40AB 0x00 364 – 16380 feedback outputs (Wheel Position and Wheel Position 2).
If the programmed tolerance is exceeded, a fault is issued.
The difference between the two wheel position outputs can be
seen in the monitor variable Wheel Position Error.
A setting of 90.0° turns off this fault check.
Encoder Position Tolerance (deg) 2.0° – 90.0° Defines the maximum difference allowed between the Wheel Position
0x40DC 0x00 364 – 16380 and the Encoder 3 Position.
This parameter should be used only for configurations where
the programmed Position Feedback Device = 0 (Analog 5 and 6)
or = 2 (Sin/Cos Sensor) or = 3 (Sawtooth Sensor).
If Position Feedback Device = 1 (Encoders 3 and 4) the Wheel
Position and Encoder 3 Position are the same. Therefore this check
should not be used when Position Feedback Device = 1.
If the programmed tolerance is exceeded, a fault is issued.
The difference between the Wheel Position and the Encoder 3
Position can be seen in the monitor variable Encoder Position Error.
A setting of 90.0° turns off this fault check.
For 360° steering, disable the fault check (set Encoder Position
Tolerance (deg) = 90.0°). This is necessary because if the wheel
were turned in the same direction multiple rotations, Wheel Position
would eventually drift away from the Encoder 3 Position due to the
small inaccuracy in the Encoder Counts Per Degree which would
build over multiple rotations.
Home Reference Tolerance (deg) 2.0° – 90.0° Defines the maximum difference allowed between the two home
0x40B6 0x00 364 – 16380 reference inputs (Home Reference and Home Reference 2).
If the programmed tolerance is exceeded, a fault is issued.
The difference between the two home reference inputs can be
seen in the monitor variable Home Reference Error.
A setting of 90.0° turns off this fault check. .
Stall Steering Speed 0 – 65535 rpm Defines the speed below which the steer motor will be considered
0x40DB 0x00 0 – 65535 stalled if it remains below this speed for the length of time defined
by the Stall Timeout parameter. When this condition is detected,
a fault is issued (code 36, Motor Stalled).
A setting of Stall Speed = 0 turns off this fault check.
