>-- >Sebastian Kuzminsky Thanks, that is a step forward, but I still have issues with the wording on the two parameters OUTPUT_SCALE and MAX_OUTPUT. Peter Wallace suggested to me use the max speed of the axis, say 20 mm/s for the first value and then 19.5 mm/s for the second value. In this way the parameters are normalized and the PID values can be compared between systems (changing the OUTPUT_SCALE also effects your PID parameters). It is therefore very confusing to read the explaination after OUTPUT_OFFSET and MAX_OUTPUT. The latter cant be in volts as the text implies. In my case the maximum is 19.5, which is way above the maximum volts a 7i29 can take (10 Volts). As PCW explained to me the reduced value of 19.5 is needed to ensure that the PWM output does not reach a duty cycle of 1, which the 7i29 would not be happy with. It gets a maximum of 19.5/20 = 0.975 DC, or 9.75 actual volts. Perhaps a note about this could be added to section 14.2 of the manual. PNCCONF could perhaps also help by setting the right value for MAX_OUTPUT to 9.75 instead of 10 when a 7i29 is selected. I hope this helps to clear the issues.
