Braking units
Brake module EMB9351-E
For lower braking powers, the brake module EMB9351-E with
integrated brake resistor can be used.
Brake chopper EMB9352-E
If a higher braking power is required, the brake chopper
EMB9352-E can be used to obtain an optimum adaptation to
the required braking power. For this purpose, the brake
chopper is operated with an external brake resistor.
Brake module and brake chopper

Although a higher brake power can be achieved by using
other resistors or by connecting a number of resistors in
parallel or series, the resistance value must not fall below
the minimum R

When brake choppers and brake modules are combined,
parallel connections are permissible.
