F = Factor
Cooling time = F * braking time
Example 1: For a braking time of 1s, a braking power of 1kW is required. The Dia-
gram shows the following:
The required values can be found in the range between characteristic F = 0.5 and
F = 1. In order to achieve operating safety, please select the higher factor, this
means that the required cooling time is 1s.

Example 2: For a braking time of 0.5s, a braking power of 3kW is required. The
Diagram shows the following:
The required values can be found in the range between characteristic F = 2 and F
= 5. In order to achieve operating safety, please select the higher factor, this
means that the required cooling time is 2.5s.
