4.4 Capacitor module. CM-1.75
This module stores the energy returned while the motors are braking.
The capacitor module should also be used when having systems that
sporadically request high current peaks from the power bus hence
increasing the bus' own capacity.
From the energy point of view, installing a capacitor module is more efficient
than installing external braking resistors.
Outside look
Module that must be connected in parallel to the power DC BUS. FAGOR
supplies with each module two plates for connecting them to the DC BUS.
