My Magnetek 333 manual shows parameter no-02 sets the maximum frequency; the
default value is 60Hz. I suspect the 503 may use the same parameters.

Well that's truly embarrassing. I looked at every parameter, but that
was hidden amongst the V/f section that I glossed over. It took a minute
or two to sort out because to change the max frequency I had first to
change the V/f characteristic from auto to manual.
Thanks Martin.
