9.4 Description of Console “PROGRAM VACC” function

This enables adjustment of the minimum and maximum useful signal level, in

either direction. This function is unique when it is necessary to compensate for

asymmetry with the mechanical elements associated with the potentiometer,

especially relating to the minimum level.

The two graphs show the output voltage from a non-calibrated potentiometer with

respect to the mechanical “zero” of the control lever. MI and MA indicate the point

where the direction switches close. 0 represents the mechanical zero of the

rotation.

The Left Hand graph shows the relationship of the motor voltage without signal

acquisition being made. The Right Hand Graph shows the same relationship after

signal acquisition of the potentiometer.

This function looks for and remembers the minimum and maximum potentiometer

wiper voltage over the full mechanical range of the pedal. It enables

compensation for non symmetry of the mechanical system between directions.

The operation is performed by operating the pedal after entering the PROGRAM

VACC function.
