7.1.4 Block diagram of power section
This type is equipped with an EMI input lter (models ADL300.-...-F-..; except ADL300-...-2M), an AC/DC converter, a
system for pre-loading DC capacitors, a DC/AC converter, a power supply unit and an integrated braking unit.
To manage emergency situations (drive power failure) the unit also envisages connection of an emergency unit
between terminals EM and D.
A specic external resistor must be connected to perform the braking function.
The connection of the external braking resistor depends on the drive size:
• (1) (4) connect the resistor between terminals C and BR
• (2) connect the resistor between terminals BR1 and BR2.
• (3) an optional external BUy braking unit can be used and connected to terminals Cand D. Refer to the BUy hand-
book for further information.
