Note!
A brake unit is required only if the DC bus voltage of the 93XXservo inverter in the generator mode
exceeds the upper switch-off threshold set under C0173 (activation of the OU monitoring function).
The brake unit avoids the activation of ”OU” by converting the kinetic energy of the machine into
heat and thus keeps the DC bus voltage below the upper switch-off threshold.
