19.1- INTRODUCTION & FUNCTIONAL DESCRIPTION
The A2VCAN electronic board gives to the modular TM70 systems an analogue output in voltage option, allow
the government of variable frequency drives with voltage control, electro-hydraulic proportional valves with input
reference in voltage, etc. The electronic board contains two output stages galvanically each other separated and
from the control common logic.

BOARD
A2VCAN electronic board is an expansion of two analogue outputs controlled by the CANopen interface. Can
generate two analogue outputs (dependent on supply voltage) with a resolution of 10 bits (1024 steps).
The A2VCAN electronic board implement, for integration into the TM70 system, an own resident software in its
microprocessor, that performs the following functions:

Communication with the LR72 electronic board through CANOpen protocol, using the standard profile
401, input/output digital/analogue (CIA DS401 - CANopen Device Profile for Generic I/O Modules).

Generates two analogue outputs in voltage according to the received instructions and the settings for
each output.
There are two types of response curves for each output:

Linear: response of the analogue output proportional to the input

Non-linear: the response of the analogue output is exponentially regarding the input. Variations of the
joystick inputs at the beginning of his movement will result in small changes of the output voltage, while
the same variations of the joystick input at the end of the movement will result in major changes in the
output voltage.
The choice of one or another profile is decided by a customization parameter P (customizable by EEPROM or
Tele-Alignment), which uses 0 for linear curve and 1, 2 or 3 for exponential curves from low to high grade.
It also can be programmed exit ramps on rise and/or fall per semiaxis. The form of response of the ramps is
under defined output type: linear or nonlinear.
