Central Braking Modules are dimensioned for braking powers with the following duty cycles:

Braking powers of the Central Braking Modules

The braking powers are subject to a cycle time of 600 s. P₁₅₀ is assumed to be the rated braking power. The braking resistors can be assigned according to these power ratings.

In most applications, Central Braking Modules are only used for occasional braking operations, e.g. stopping a drive in an emergency. Low-cost braking resistors in IP21 degree of protection are specifically offered for these types of applications; these braking resistors are dimensioned for braking powers P_BR with the following duty cycle:

Duty cycle for braking resistors

Braking resistors with a higher braking power and shorter cycle times are available on request.
