Under voltage error

I have a question regarding Simucube1 (Sim-Plicity SW20 regarding an under voltage error I get on power up.

My hardware configuration:
Simicube1
Small Midge
Hardware version Revision 2(r005)
IONI firmware 10716

Problems arise when:
When I power on the system the shaft starts to spin as though it is calibrating and then it stops suddenly and I get the error Motor Faults: Under Voltage! Initialization Fault! Fault Location IS:0

How it behaves:
As Above
How I would expect it to behave:
For 3 years it has completed the calibration fine

I have attached following files:

I also would like to share that (additional info).

Note: you can tag the best answer as solution. This helps others to find the solution to the same question.

It would be helpful if you could post screenshots from Granity.

[Drumbstick]

Thanks for the reply Joe

So when I try to connect on USB it says no devices found.

On COM4 I get the following. If I select a device it says unknown device type

[Drumbstick]

Couple more things

I use a wireless wheel and can connect to that fine in the Simucube software

This is the bottom of the Granity screen

Error log in Simucube says

Drive init stage 4, phasing, current position : 437

Repeats for all the entries

If I hot the stop button it recognises I am doing so in the software

[Drumbstick]

So moving forward I now have it working in Granity (User error)

It prompts me to restart the drive when I connect in Granity and then appears to connect. What do you want me to do

[Drumbstick]

And now I have a different error

Motor Faults:undervoltage! initialization Fault! Fault Location ID: 440502

I am guessing the power supply is giving up the ghost? backed up by I don’t think the Fan is spinning as fast as it did before

[Mika]

You need to software enable the drive in Granity at the connect tab. Then you need to see what happens.

[Drumbstick]

Thanks Mika done that and I get this message

The control panel then looks like this

The error still persists

[Mika]

So it still might be an under voltage fault. What is the under voltage fault limit? Its on the fault limits tab.

[Mika]

Oh I see its 25 V. Can you try to lower it to 20 V? And save settings to drive.

[Drumbstick]

Tried it at 20/10/5 no matter what the error stays the same

When the shaft spins it gets about 75% or more through the config then it just clamps down

[Mika]

Try to lower the maximum motor current.

The early Simplicity SW20 units had a peculiar PSU configuration and perhaps something in that circuitry is getting tired…

[Drumbstick]

You sir are a genius

That got it anything under 9.8 and it configures fine

[Joe]

@Mika thanks for chiming in. I had a very busy day and was just able to check back in.

Yes the SW20 had the dual power supplies and was a little finicky at times. I wonder if one of the power supplies has become weak?

Glad this is sorted for now.

If the problem persists I personally would be tempted to move the components into a different enclosure and use a Meanwell NDR-480-48 or SDR Power supply.

[Drumbstick]

Thank you both truly blown away by your level of support, especially for a product I did not purchase directly from you.

I will look in to getting another enclosure and power supply

[Joe]

The OSW guys stick together.
Very happy to help whenever needed.

Just curious, where do you live?

[Drumbstick]

Thanks Jo indeed solidarity in numbers.

I line on the south coast in the UK
