Protecting the resistor cable against short-circuits
The brake unit requires the use of brake circuit fuses. The fuses protect the brake chopper
and the brake circuit cables in a cable short-circuit situation.
Controlling the brake chopper from an external control
location
The brake chopper can be controlled from an external control location via a fiber optic link
(terminals V22 and V23 on the chopper control board). Using the link, it is possible to
synchronize several brake choppers. For instructions, see section
.
