INSTRUCTION NAME: VLIM (velocity limiter)
DESCRIPTION: This instruction limits the rate of change of the SVA input to a predetermined
value. The SVA output is the same as the SVA input unless the rate of change of the input exceeds
the velocity limit specified by the analog value in operand 1. If the velocity limit is exceeded, the
output will change at a rate equal to the velocity limit.
The SVD output equals 0 when the SVA output is not limited. The SVD output equals 1 when the
SVA output is limited.
