Have you tried it with another type/make controller? Same problem?
A list of controllers and their max. rpm for given number of magnetpoles. Maybe you are hitting the maximum?

CW and CCW justs indicate different winding directions, it has nothing to do with a clock. One could also use black<>white or (+) <> (-) or hot<>cold etc. to inidicate opposite winding directions. 'We' always use uppercase<> lowercase characters AaBb ... etc
All AXI's use LRK or dLRK, they only differ in size and number of winds.In the case of dLRK, make sure whether the number of winds is given per tooth or per two (neighbouring) teeth! More axi rewinds:
