INFORMATION. In case of micro-surges or total mains power outage, this module ensures
the stability of the +24 V DC to feed the control circuits of the drives connected to the DC
BUS and maintain it for as long as the emergency stop of the motors lasts, thusstopping the
axes in a controlled manner. This is what is known as dynamic braking.
