Patent ID: 8798874

Claim:
A system for limiting contact between an attachment and a boom of an industrial machine, the system comprising: a first resolver for determining a first position of a first component of the industrial machine, the first resolver having a first resolver count; a second resolver for determining a second position of a second component of the industrial machine, the second resolver having a second resolver count; and a controller configured to determine a minimum resolver count for the first resolver based on the second resolver count and a non-linear approximation of a boom profile, and limit operation of a first motor associated with the first resolver or a second motor associated with the second resolver based on the first resolver count, the second resolver count, and the minimum resolver count, wherein limiting operation of the first motor or the second motor includes the controller entering a field strengthening mode of operation, a reduced speed mode of operation, and a zero speed mode of operation based on the first resolver count, the second resolver count, and the minimum resolver count.
