Hi,

I´m configurating a Micromaster drive in a crane. The MM is not able to stop without a brake resistor, I´ve already installed one but is not enough, it improved the performance but still sometimes has fails of overvoltage, overhall when the crane is accelerating.

I have another resistor ready to be installed somewhere but I would like to use both in the crane to try if it´s enough.

Is it possible to install both in the same drive? How to connect? Serie or parallel?

Both resistors code is: 6SE400-4BD12-0BA0

Thanks.

6SE400-4BD12-0BA0

Anyway i´ve tried them in parallel and they work good.
