Hello Friends,
Heidenhain 135 ST, software 214 383 (common drive with backlash compensation), in MDI and Auto mode doesn’t issue VCMD (analogue output to the drive).
After a minute there appears on the screen :GROSS POSITIONING ERROR.
I changed the output operational amplifier, but no use.
Override switch is OK.
Could you advice me, does it need some additional input signal???
I see :AXESS RELEASED X,Y,Z signals , but they are outputs,
In my case the system output VCMD (analogue output to the drive) is ZERO mVolts for any axe moving command (X,Y,Z), there is not M function in the block.
