Normative answer (in Dutch), I have no practical experience either way: https://www.rijksoverheid.nl/onderwerpen/minimumloon/vraag-e...

Your employer has no obligation to compensate for your internship, but is not prohibited either. There is no minimum or maximum amount set for this compensation.

The focus for internship should be on training, not work. If the Inspectie SZW (employment auditor) finds that the internship consisted of mostly paid work, the employer will be ordered to salary the intern according to normal wages [effectively, minimum wage].

However, there is a practical limit to compensation: students earning more than E20,000 a year are no longer eligible for the student loans you mention.

AFAIK that maximum is only for the "gift" that was superseded by a loan which has no max income limit.
