This braking unit is an option for variable speed drives of Altivar range. The minimum resistor value to associate is 1Ohm. This braking unit allows Altivar 71 drives to operate while braking to a standstill or during “generator” operation, by dissipating the energy in the braking resistor. Its protection index is IP20. Thermal protection is provided by an integrated temperature...

This network braking unit can be used to return the energy from the motor to the line supply. It allows a very quick and yet smooth transition between starting and stopping. It is therefore ideal for use in applications where strong braking dynamics are required. It is also very well suited to use on unstable line supplies. It provides IP 20 degree of protection.
