6.5.2.24 ADT-Angle Delta Torque
Step type Id: 31
Parameters: Delta Torque, Angle, DIR (Direction).
Function: 1. Run Angle degrees in the reverse direction.
2. Measure the torque when the Angle is reached and store this value as Tlast.
3. Stop the spindle and wait until zero speed is reached.
4. Run in the forward direction until the torque Tlast + Delta Torque is reached.
5. Shut off the step.
The same speed and speed ramps are used both when running in the backward and the
forward directions.
If Check angle is used it will report the total angle without compensation of the lash.
The step is intended to be used in an injector pump setting application and the proposed
tightening sequence is:
Step 1: T = 25 [Nm]; Direction = Forward
Step 2: T = 3 [Nm]; Direction = Backward (to deal with the lash in the transmission).
Step 3: ADT = 5 [Nm] / 60 [deg]
Step 4: A = 30 [deg]; Direction = Backward
Step 5: CE
