About dc governor braking energy note:
The most simple of dc speed brake most efficient way is to use the regeneration, but this way feedback braking requirements governor must be reversible phase limit operation of the four, for some industries, such as wood for rotary cutting units, and the cost will be relatively high, if the two phase limit speed, relatively low cost will, the braking energy. Using the principle of braking energy is the motor of the brake excess energy consumption in external braking resistance above. For its connection mode I will no longer say, here I speak about my time in commissioning the problems and the solution method: the braking energy and not to want simple will brake contactor and braking resistance connect to come in, should pay attention to in the brake is must give motor excitation. At that time for the brake problem of the magnetic field to for a long time, given the external magnetic field, the rating is not very safe, motor later can to provide their own thought of governor after being stopped excitation? Carefully read all instructions, finally in the reserved menu found a call "spare excitation" the parameters, the parameters are as follows: first, the usage of the super secret password is to use X1311 0, into reserves, will spare excitation menu after the proportion of high, largely in the rated. Second must pay attention to the governor of the magnetic field control connection mode to external excitation wiring, the parameters of preservation. Finally the attention is braking energy at the same time in the first governor to disconnect can end, can't break its start end, if the start end, it off spare excitation is isn't working.
