The Optimal Braking is active as described at P0185. This assures the minimum possible decelera-
tion time without using dynamic or regenerative braking
Automatic control of the deceleration ramp. The Optimal Braking is inactive. The deceleration ramp
is automatically adjusted in order to keep the DC link below the level adjusted in P0185. This proce-
dure avoids the overvoltage fault at the DC link (F022). It can also be used with eccentric loads
DIx = 24 V: Braking actuates as described for P0184 = 1
DIx = 0 V: The Without Losses Braking stays inactive. The DC link voltage will be controlled by
the parameter P0153 (Dynamic Braking)
