Hi
How do you create a custom error message?, for example when an input
is activated or missing (drive nok, overload, etc).
Thanks in advance.

The usual sort of encoder is not desperately convenient for mounting
on a machine tool spindle, as such applications generally require a
sizeable through-hole.
Car engines nowadays use a pickup on the crank to tell the engine
controller the current crank angle. These used to be a proximity
sensor
The chip I used to translate the differential encoder level to a level
compatible with the LPT port was a Texas Instruments AM26C32CN.
That chip, with a 5 volt supply and a 4700 pf decoupling capacitor on a
piece of perfboard was all that was required to do the 3 channels from
the encoder.
I
Hi again
Managed to get an hour in the workshop unexpectedly, linked
encoder.0.Phase-Z to the index pulse as well and eureka it works
properly, let threading tests commence!
May yet fit the encoder, will see what you think of the one I have.
Thanks for your help

Don't have time for a long reply right now (and this topic really
needs a long reply). Short reply below:

Does anyone know how to set up BLDC motor control?
I have a number of phase/step tables, one for a different motor to the
one I am trying to drive, one for the driver chip on the driver board
I have, and one from the board manufacturer.
Firstly, the generic BLDC motor data sheet defines a set of
