9.3 MOTION SYSTEM - BLOCK DIAGRAM
For a better understanding of the motion system, pease refer to the diagram below.
The CPU Board (TRM-357) provides two analogic signals (0-3V) to the Power Board
(TRM-358).that are the inputs of the DC driver, which controls the steering motor with a +/-
24V output.
The platform is moved by two AC motors. Each motor is drived by a frequency converter
that is communicated with the CPU board through a RS-485 connection.
These drivers also have a “ready” input (RD). When the input level is high (24V), the
drivers are operative and transmit to the motors the orders given by the CPU board. If the
Emergency Stop button is activated, the RD input falls down to 0V and both drivers are
disabled.
The high level (24V) is generated by the left driver, drawn in the block diagram below. The
right driver is not shown.
The position signals processed by the CPU come from potentiometers coupled to the
shafts of the motors.
