Try inverting the encoder direction in the plugin.

Thanks. Will try tomorrow.

Hi Mick,
by using the CSMIO you have added a layer of complexity that is making your job impossible.
You don't know whether its Mach, the CSMIO or the servo/drive and you are floundering.

Disconnect the CSMIO, put the servo drive in position mode and manually pulse the step input
to confirm the servo and drive operate correctly. If and when you get the servo and drive operating
THEN add the CSMIO, without Mach to start with.

If you don't have a signal generator to pulse the step input get a rotary encoder and use one channel
and spin it for all its worth. You will have to use electronic gearing to get useful results, a good learning
curve in itself.

Hi Craig
Yes this is confusing me somewhat.
I'll try what Hood suggested then look at your suggestion.
Reason being is I will have add addition wires to the Cn1 connector to try this.
I do have the old MPG wheel which I think I could use as a pulse generator.

Hi,
you've also got the tuning/setup software. In position mode you can program indexed moves, you don't even need wires
on the pulse inputs.

I don't know what you are doing wrong, surely the programmed current limits would prevent the drive from drawing enough current
to trip your breaker. Either way I would not hook up the CSMIO until I was 100% that the drive and servo were perfect, including sensible
current limits.

Schnieder were good enough to replace one drive....how do you think you would go asking for a second?

Hi Craig
Not really sure what you saying.
I can't contact Schneider and say I want another drive when there's nothing wrong with the ones I have.
As far as programmed current limits. This is set in P1-78.
It's factory set at 19amp. Which is possibly why the first drive gave up. I wasn't aware I need to change that parameter. It's now set to 13.5amp motor max current.
I am able to use the software and jog with no issues and autotune.

Hi,
use the tuning software to set up a series of indexed moves. You should also be able to set a number of free running speeds.

Hi,

It's now set to 13.5amp motor max current.

I think this is still way WAY too high. If I'm not mistaken that is the per phase current.....13.5A per phase!!!

Do the calculation:
DC Link current= 3 (phases) X 13.5 (A per phase) / (square root 3)
                      =23.4A
Single phase input current= DC Link current / power factor
                                     =23.4 / 0.5
                                     =46.8A
Its no bloody wonder you 'trip the electric'. Reduce the max current down to a couple of amps.....once you get things sorted then increase it to somewhere
close to maximum. Remember you are trying to use an external controller to close the loop, the CSMIO, and it is highly probable during the set up you will
have maximum current events, so why have the max set at a value that threatens to damage the drive, the servo and your power supply. This is supposed
to be a 1hp axis servo......not the motor that powers the earth around the sun!

Next issue is that there are four parameters that set the maximum current, P1-78 through P1-81, ILIM,IMAX,DIPEAK, and DICONT. Not 100% sure what they all mean
yet, but I bloody well know none of them should be 13.5A!!!!

Hi,
the drive data suggests 4.5Arms at continuous rated current, probably per phase.
It also suggests 13.5A rmsmaximum current.

Try:
DICONT=4.5
DIMAX=13.5
ILIM=4.5
IMAX=4.5

Hi Craig
Yes that's what they are set to now.
