6.5.4.8 Check T/T3 (Current as Torque)
Parameters:
T/IH
(Torque/T3 high),
T/IL
(Torque/T3 low),
TI
(Time)
Function:
The average torque vs. the average current measured during the last TI seconds of the step
is measured and checked to be between the high limit T/IH and the low limit T/IL.
Both limits are optional. Leaving them blank disables the check but the result value is still
calculated and reported.
This check requires that at least one sample is collected after the torque spike elimination
phase. If not, and at least one limit is specified, the steps status is set to
Fatal
and the error
bit of the respective limit is set.
