The Torsion Bar Setup is a compact demonstration setup that demonstrates some important features of a real machine:
The Torsion Bar Setup v2.0.
The first version of the Torsion Bar (v1.0) setup is equipped with a PWM controlled H-bridge motor amplifier. This corresponds to a velocity-controlled motor. The new Torsion Bar v2.0 contains an ELMO Whiste motor amplifier that can be used in current-control, voltage-control and position-control mode. The Torsion Bar v2.0 setup uses the current control mode, which corresponds to a torque-controlled motor.
The interface of the ARM 7300 has been limited to the following inputs and outputs:
•2 x LVDS Quadrature Encoder Inputs.
•1 PWM-to-current output, to drive the motor via an ELMO Whistle current amplifier which is mounted below the interface board.
•2 x LED. Two LED's are present on the board.
