Variable name
Description
Mean T
Mean T1
Mean T2
Mean T3
Mean torque during end of step. Produced by the "Check mean torque" check.
DT Mean T
The mean torque measured during the time interval TI2 of the DT - Run until Dyna-
Tork
TM
, DT2 - Run until Dyna-Tork
TM
, method 2, and DT3 - Run until Dyna-Tork
TM
,
method 3 steps.
Value is based on control channel used for step.
DT T
The torque measured when a DT - Run until Dyna-Tork
TM
, DT2 - Run until Dyna-Tork
TM
,
method 2, or a DT3 - Run until Dyna-Tork
TM
, method 3 step switches to using the DT
torque as target.
A Win Hi T
A Win Hi T1
A Win Hi T2
A Win Hi T3
The highest torque measured in the angle window. Produced by the "Check torque in
angle window" check.
A Win Lo T
A Win Lo T1
A Win Lo T2
A Win Lo T3
The lowest torque measured in the angle window. Produced by the "Check torque in
angle window" check.
Ti Win Hi T
Ti Win Hi T1
Ti Win Hi T2
Ti Win Hi T3
The highest torque measured in the time window. Produced by the "Check torque in
time window" check.
Ti Win Lo T
Ti Win Lo T1
Ti Win Lo T2
Ti Win Lo T3
The lowest torque measured during time window. Measured by “Check torque in time
window”.
A
A1
A2
The step angle. Produced by the "Check angle" check.
Time
The time that the step was run. Measured from that the servo is started until it is
stopped. Produced by the "Check time" check.
T / T3
T1 / T3
T2 / T3
The mean value of torque vs. the mean value of current both measured during the last T
s of the step. Produced by the "Check T/T3 (Current as Torque)" check.
Relax A
The angle measured from that target is reached until the step is shut off. Only produced
by the DT - Run until Dyna-Tork
TM
, DT2 - Run until Dyna-Tork
TM
, method 2, and DT3 -
Run until Dyna-Tork
TM
, method 3 steps. This value is based on the control channel used
for the step.
Release A
The release angle measured from the negative peak torque until the point where the
line, trough the peak torque point and the shut off point, cuts the angle axis.
Is produced by the “LT - Loosen until torque” and the “”RA - Release angle steps. This
value is based on the control channel used for the step.
