Variable name
Description
Shunt Drift T1
Shunt Drift T2
Reports the Shunt claibration drift for the torque transducer, that is the difference
between the this Shunt calibration measurement and the previouse one. Measured by
the spindle during Spindle functional test in a D - Diagnostic Step.
Position A
The result of the check Check Position (only available for Gauging)
Low Spot T
Low Spot T1
Low Spot T2
Low Spot T3
The lowest torque. Produced by the Check low spot torque check (only available for
Gauging)
Null Pos A
The distance to the Null position after the current step (only available for Gauging).
Half Pos A
The distance to the Half position after the current step (only available for Gauging).
Peak Pos A
The distance to the Peak position after the current step (only available for Gauging).
Low Pos A
The distance to the Low position after the current step (only available for Gauging).
Zero Cr. A
Zero Cr. A1
Zero Cr. A2
The Zero crossing measured by the Zero Crossing check
Fail Safe T
Fail Safe T1
Fail Safe T2
Fail Safe T3
The Fail Safe Torque Limit used in the step.
Fail Safe A
Fail Safe A1
Fail Safe A2
The Fail Safe Angle Limit used in the step.
Min T Rest
Min T1 Rest
Min T2 Rest
Min T3 Rest
The Min. Torque restriction limit used in the step.
Angle A TStart
Angle A1 TStart
Angle A2 TStart
The Torque start used in the angle check, i.e. the torque value there the angle
measurement is started. Only used if start condition of the check is Torque.
Step var. 1..40 T
General cycle data variables for the checks, scaled as Torque if different torque units are
selected in reporters.
Step var. 41..80
General cycle data variables for the checks
When including the limits of a variable both the high and the low limit will be included in the report. If you
choose to include the SPC values all three values are reported together.
