Steps to enable the dynamic braking:
Connect the braking resistor (Refer to the item 3.2.3.2 - Dynamic Braking, of the user's manual).
Set P0154 and P0155 according to the used braking resistor.
Set P0151 or P0185 at the maximum value: 400 V (P0296 = 0), 800 V (P0296 = 1, 2, 3 or 4), 1000 V
(P0296 = 5, 6 or 7) or 1200 V (P0296 = 8), according to the case, in order to prevent the activation of
the DC voltage regulation before the dynamic braking.

Description:
Adjust this parameter with the ohmic value of the used braking resistor.
If P0154 = 0, the braking resistor overload protection is disabled. It must be programmed in zero if no braking
resistor is used.
