7i40 jog acceleration

sorry if I go back to ask, I adjusted the acceleration perfectly in g0 g1 but in jog mode is very bad.
it accelerates and decelerates too slowly .. I can not understand why.
maybe it should be set apart?
the system is closed loop 7i80 + 7i40.

sorry, it was mpg-accels for hb-04 pendant that also affects the jog ..
