Output stage board

64-xx – CHESS x – DPM – ALX 92x – Novexx PA-1x6

General notes

There are two different versions of the output stage boare in circulation
(see ). T he newer board doesn´t require any setting of the sensor by
potentiometer any more. Therefore, the pots are missing in the newer
layout (= distinguishing feature).
Please keep in mind the following points, when you replace or check an
output stage board:
PIC version:
The PIC must carry a label with the writing "M04A V3 C73"!
Jumper setting:
The jumper setting must match the motor which is ought to be driven by the
output stage!


See paragraph Jumper settings on page 9.
(only older board layout) Sensor setting:
The sensor current must amount 25 mA!


See paragraph Sensor setting on page 10.
