Oh I have seen EMI shielding tape on some cables but I did not know what it is until I have googled for it after your comment. Seems like something to try out.

Oh I have seen EMI shielding tape on some cables but I did not know what it is until I have googled for it after your comment. Seems like something to try out. Motor is 20kw driving less than 1 meter from installation. It is not standing there but it is mounted on machine, which comes at the spot from time to time, and while passing by it causes resets.
