Principle of gear mode.
As mentioned on the previous pages the motor will follow the input signal synchronously
to a certain extend according to the gear ratio setup. There are, however, a few other
parameters which are vital for success in the actual application.
These parameters are:
Velocity
The value of the velocity register will be respected at any time when the
motor is in gear mode. Therefore, care must be taken if this is set lower
than the equivalent speed of the external source producing clocks to the
gear input since it will be a limiting factor.
Acceleration
Similar to the velocity register the acceleration setting will be respected
at any time and if set lower (slower speed rise time) than the external
source producing the clocks it will start to be a limiting factor.
Below can be seen an example of the relation between applied clocks and the actual mo-
tor movement when having velocity and acceleration set to low values.

No acc.,speed or decel. control is included.
The input clock demand a prompt high speed but the motor has to respect
the setting in the acceleration register and limit the speed increase vs time.
As result the motor will slip behind were it is supposed to be.

Even the fact that the motor has slipped behind during acceleation it still has
to respect the setting in the velocity register (V_SOLL) register and limit the
speed accordingly.
The motor calculate continuously «on the fly» the necessary deceleration length
and starts decelerating according to the the setting in the acceleration register.
The motor will reach target (80 counts) exactly without any overshoot.
