General information
Availability of option
This option is available for the following S120 Cabinet Modules:
● Basic Line Modules
● Smart Line Modules
● Active Line Modules
● Motor Modules in chassis format
Description
Braking units may be required for drives that support regenerative operating conditions but
have no other facility for feeding energy back into the supply system.
The braking unit comprises two components:
● A Braking Module that is installed in the Power Module
● A braking resistor to be mounted externally ( degree of protection IP20).
The braking unit functions as an autonomous unit, and does not require an external power
supply.
