7.6 Changing During Operation (Operation Speed, Target Address)
7.6.2
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.

For the parameters, control data and monitor data, refer to Chapter 11
