The standard MCBL2805 is
layed out as a Velocity
Controller. The command
velocity is given as a voltage
signal at the analog input.

In this operating mode the
RS-232 is not required but can
be used to alter configurations.
More on the topic of “Altering
Configurations” to come.

Diagram 1:
Velocity control with command velocity from the analog input.
