Brake resistor

Introduction

iSV57s virtual brake resistor

The iSV57 offers a virtual brake resistor, means, it will release a certain amount of reverse current into the motor coils.

External capacitor

External brake resistor

Since the amount of current, the iSV57 can release into the coils is limited, it might happen, that the over voltage protection of the iSV57 can be triggered at very high force and speed. Resulting in a temporary shutdown of the servo. To prevent this, an external brake resistor circuit might be used, which can absorb more power than the iSV57 will produce, when driven by the user.
