6.5.3.7 Torque Profile
Parameters: TnStart, AnStart, AnStop, TnHigh, TnLow, where n is in the range [1..3].
Function: Checks that the torque in the three angle windows defined by TnStart and the pairs AnStart
and AnStop, is within the unique limits TnHigh and TnLow. The angles are measured from
from the start point according to the step angle definition if TnStart isn‟t configured and from
TnStart if the parameter is used.
TnStart, AnStart and/or AnStop may be left empty. Leaving AnStart empty corresponds to
the beginning of the step while an empty AnStop corresponds to the end of the step.
TnHigh and/or TnLow may be left empty. Leaving them empty disables the test against the
limit in question. Note that if none of the torque limits is specified then TnStart, AnStart and
AnStop must also be empty and the restriction is not used.
