Gear Mode.

In this mode, the QuickStep motor functions as in a step motor driver. The motor moves
one step each time a pulse is applied to an input.
Velocity, acceleration and deceleration are determined by the external frequency but can
be limited and controlled by the QuickStep motor. In addition, the QuickStep motor also
provides a facility for electronic gearing at a keyed-in ratio in the following intervals:
- MIS17x, 23x, 34x, and 43x: 1/2147483647 to 2147483647/1.
Example:
A MIS231 motor has a resolution of 409600 steps/rev. and an encoder is connected
which has a resolution of 2048 counts/rev.
If one revolution of the encoder should result in one motor revolution the Input must be
set to 2048 and the Output to 409600.
If the motor must run 5 revolutions because there is a gear with a reduction of 5:1 the
output must be set to 5 x 409600 = 2048000 instead.
Notice that a very high ratio may cause unstable behaviour in the motor speed.
