Changing the operation speed with the operation speed change function

This function is possible to change to the specified new operation speed at an arbitrary timing.
However, the speed does not change during mechanical zero return after detection of the near point DOG and
start of deceleration to the creep speed.
1. Set as follows when changing the operation speed using the operation speed change
function.
