Set the limit of taxonomy per page

 $ency_args = array(
'taxonomy'   => 'mycategory',
'orderby'    => 'name',
'order'      => 'ASC',
'hide_empty' => false,
'posts_per_page'    => 6,

how can i set the limit of showing of taxonomies in this situation, because post_per_page doesn't work? I want to show by default 6 taxonomies.
