If you want to use MINDISTANCE you have to set the SIZEUNITS parameter
at layer level like this:

LAYER
 ...
 SIZEUNITS meters # one of [pixels|feet|inches|kilometers|meters|miles]
 ...
 LABEL
  ...
  MINDISTANCE 500
  ...
 END
 ...
END

So the label wouldn't repeated for distances smaller than 500 meter.
