Expose controller property to route's model function

I've defined some properties in a controller for a pagination:

import Ember from 'ember';

export default Ember.ArrayController.extend({
  limit: 1,
  skip: 0,
  pageSize: 1
  }
});

I'd like to access limit in the Route's model-function but I don't know how.

import Ember from 'ember';

export default Ember.Route.extend({

   model: function(params) {

      console.log(this.get('controller').get('limit')) <- doesnt work for example
      return this.store.find('post', {limit: 1,
                                      sort:'createdAt desc'});
   }
});
