Description / Text References
This signal represents car position/motion. It is abstracted from
the motor velocity encoder or tach signal. The signal toggles low
or high with every 32-inches of motor travel. Increasing fre-
quency = increasing rate of position change.
High = Pre-energizes motor field as doors are closing and
demand occurs.
This is the actual pretorque signal sent to the drive and used to
pretorque the motor. This is filtered representation of the raw
pretorque "demand" signal, captured as the doors close and
used to pretorque the motor as needed depending on the weight
in the car.
This is a representation of the raw pretorque "demand" signal. It
will react to car load changes (i.e., doors open, passengers load-
ing/unloading).
High = SCR current sensor signal offset positive.
High = SCR integrator signal offset positive.
When the car is still, this signal is high. When the car is travel-
ling at a rate in excess of 40fpm, this signal is low.
Filtered speed feedback signal.

High = sufficient motor field current has been achieved. Differ-
ent percentage of forcing, depending on mode. Inspection =
60% of forcing. Other, 80% of forcing.
Speed signal synthesized from armature voltage and current.
This signal represents the lower margin of tach error allowed at
contract speed before a tach fault is generated. Display with
Speed Feedback signal to see the margin. If Speed Feedback
crosses Tach Error Lower Limit the tach fault will be generated.

page 2-59. Please refer to "Tach Error Tripping Threshold
Adjustment" on page 4-41.
This signal represents the upper margin of tach error allowed at
contract speed before a tach fault is generated. Display with
Speed Feedback signal to see the margin. If Speed Feedback
crosses Tach Error Upper Limit the tach fault will be generated.
