3HAC17326-1/02 ABB Drive controller module robot card

Description

The robot computer, controls the system’s I/O, axis
control, serial communication and teach pendant
communication. It is the first unit to start after a cold or
warm start. The red LED on the front of the board goes
OFF immediately when the system is reset and goes
ON again if an error is detected in the tests. The robot
computer releases the main computer when the
preliminary diagnostics have given the go-ahead signal.
The read and write memories of the robot computer are
battery-backed.
If the system does not start at all and the LED on the
robot computer goes ON, the error is probably in the
robot computer, but may also be caused for other
reasons indicated by the diagnostic messages.
It is not possible to carry out diagnostics on the board
in the operation environment and, therefore, if the robot
computer is faulty, it must be replaced.
If the Robot Computer board is replaced, take the
EPROM chips from the old board and put them on the
new board. Insert the Robot Computer board in the
correct slot. (See Figure 2-4) The system software will
then have to be loaded and the system parameters
need to be loaded. Then the resolver counters need to
be updated also. Refer to Chapter 3 – Loading System
