As the chart below shows, when multiple units are applied in parallel,
the first brake chopper should be set as "MASTER"; all others should be
set as "SLAVE".

Definition for braking ratio OT %
As shown in the diagram below, braking ratio OT % is the ratio of the braking
time and the braking period, usually represented by percentage. When OT %
is selected, the resistance and the power of brake resistor must be taken into
consideration so that enough time can be ensured for the brake chopper and
the brake resistor to release the heat generated in the braking process.
