Note: terminals L1-L2 and L3 are not present in -DC versions.
5.1.9 Braking unit connection (optional)
L1 L2 L3 BR1 BR2 CDU VW
Braking resistor
Note! ADV200-...-4
Terminals BR1/BR2 are standard up to size ADV3220, optional in sizes ADV4300 ... 5550, larger sizes
are not used.
From size ADV5750 an optional external BUy braking unit can be used and connected to terminals C
and D. Refer to the BUy handbook for further information.
Recommended combination braking resistors: see paragraph 10.4.
ADV200-...-4-DC
Terminals BR1/BR2 are not present.
An optional BUy braking unit connected to terminals C and D can be used. For further details reference
should be made to the BUy manual.
You MUST set the parameters for controlling braking resistance overload (MENU
22.6) to detect overheating of the braking resistance. Without this information on
the resistance used, you have to monitor the overtemperature switch on the resist-
ance. Overheating may be caused by:
• ramp times too short or braking too long
• wrong braking resistance size
• input voltage too high
• defective braking transistor on inverter or on braking module.
