Other Analog Control Unit; Standard Version - Zapi ACE3 User Manual

The Procedure for automatic potentiometer signal acquisition is carried out using
the Console. This enables adjustment of the minimum and maximum useful
signal level (PROGRAM VACC function), 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 sequence of procedure is described in the programming console manual.
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.

3.3 Other analog control unit

3.3.1 Standard version

1) Input A10 is an analog input, whose typical application is for proportional
braking. It should be in a 3 wire configuration. Potentiometer value should be
in the 0.5-10 kΩ range. Generally, the load should be in the 1.5 mA to 30 mA
range. The signal range is from 0 to 10 V.
2) Connections A23 (PTHERM) is used for a motor thermal sensor. It can be
digital (on/off sensor, normally closed) or analog. See also chapter 8.3 for
more explanation.
