High Voltage Motor Control Platform - Javascript error in the FreeMASTER ACIM demo app

johnwood101 — Tue, 30 Aug 2022 06:14:46 GMT

I bought the High Voltage Motor Control Platform with the

HVPKV46F150MUG_high_voltage_processor_module.

The firmware compiled and uploaded OK with latest Linux MCUxpresso ide

and installing the

SDK_2.x_HVP-K46F150M

into the ide and then importing acim example via "Import SDK examples" option.

No problems with the compile / firmware upload.

Tried to power up the motor with FreeMASTER 3.2 - running under Virtualbox Windows VM

using an old (2017) copy of

acim_ref_sol.pmp. It connected correctly at 19,200 baud but with a lot of non-javascript 'missing freemaster variables errors',

but it would spin the motor. I couldn't complete the motor tests because of the missing variables. It would just report crazy negative estimated speeds.

Now, I tried instead the same acim.pmp which came with the above SDK.

Even though it does connect over UART at 19200, it doesnt run at all because

I just get the following error, and the GUI is not operational

--- See attachment for image of error

Is there a newer version of ACIM or anything else I can try.

Strangely, even the old acim_ref_sol.pmp which used to kind-of run,

now reports these same javascript errors as in the attachment.

thanks for looking at this.

I can't really get past this error.

Thank you so much for your interest in our products and for using our community.

Just to clarify, I'm assuming you're using the ACIMKV46DEMOUG User's Guide as a reference.

On the other hand, I recommend you to use FreeMASTER tool 3.1 – Linux installer instead of using Virtualbox Window, you can download it from FreeMASTER Run-Time Debugging Tool.

Hope it helps you. Please let me know if you have more questions about it.

Have a nice day!

Yes, I am working from instructions in ACIMKV46DEMOUG which seems to date from 2020.

but I cannot find a recent acim_ref_sol.pmp file to operate the the demo.

The only one I can find is from 2017 as comes as part of MCRSP_ACIM_V1.2.0

This 2017 software expects to be installed on Kinetis Design Studio 3.2.0.

When I compile under KDS, the firmware doesnt run --- communication cannot be established with Freemaster.

If I build the more recent MCUexpressoIDE ACIM project, the firmware does run, but I believe that now the old 2017 acim_ref_sol.pmp is not properly compatible with this firmware - and hence the warning messages about unknown FreeMASTER variables.

When I try to setup a motor, the sensorless mode doesnt run correctly (it only works about 400rpm).

I tried FreeMASTER3.1 but on Linux, it only installed the LITE version, not the full version.

I think if I had an acim_ref_sol.pmp which is more up to date then my problems would be over.

( The latest SDK for MCUexpressoIDE to match for the hvpkv46f does not include a new pmp file.)

I found one called acim.pmp somewhere on the internet but this does not work.

I think if you had an newer acim_ref_sol.pmp to match the MCUexpressoIDE ACIM demo, then my problems would be over.

best regards

John

Sorry, what version of SDK are you using? Since the SDK for HVP-KV46F (2.8.0) does have the .pmp file in the following path:

On the other hand, I must admit that I am working on Windows and we have not tested anything about this on virtual machines on Linux.

If you still have questions regarding FreeMASTER, I recommend you ask in the FreeMASTER Community where our experts in this tool can help you in more detail.

Hello,

yes, I am using HVP-KV46F (2.8.0)

and I reloaded it again, remembering to tick the freemaster tickbox, and now found acim.pmp.

However, when I run it, I still see this message:

It looks like the error is to do with Javascript.

( The old 2017 acim_ref_sol.pmp which came with

High Voltage Motor Control Platform software

does not show this error, so it must me something introduced

between the two version of the .pmp file. )

Please could you tell me which version of Windows is it that

the acim.pmp is running on for you?

( the acim.pmp which comes with HVP-KV46F (2.8.0))

I will go and buy a bare metal Windows machine to check if it works.

thanks

John

thanks for your help. I have it running correctly now on the Windows machine, but after motor identification, the control is not stable below 300rpm on a 1500rpm 0.55kW ACIM in sensorless FOC .

I had previously tried ST's motion control development system X-Cube-MCSDK and had the same problem with it's FOC algorithm, so this is not unique to NXP / Freescale code.

I've also tried a commerical Invertek inverter which works correctly, and just now I tested the TI InstaSPIN HV development kit on Windows, and it will run the same motor stably down to 20rpm, so I think I'll be using the TMDSCNCD280049C processor for this project.
