A device of the series b maXX 4100 consists of the following parts:
A: Power unit
(converter)
This part is a power converter combination which is build up with power semiconductor
components. The feeding in and feeding back is implemented with a B6-IGBT transistor
circuit, which has an HF mains choke connected to. The power factor on the mains side
is in each operation point cos φ = 1. The DC link voltage supplying the power module con
-
nected to the DC link is 640 (760) V (U
DC
). Permanent part of power unit is a charging
circuit. Without taking actions at switching on the mains connection the DC link capacitors
lead to invalid high charge surge currents from the mains. In order to avoid these charging
surge currents the starting current is limited by a charging circuit. Therefore a buck con
-
verter is integrated, which is limited to charging current to charge current to about 1,5 A.
B: Controller unit At reaching a DC link voltage of 500 V (U
DC
) when mains voltage is 400 V and the de-
crease of the charge current to zero the buck converter is switched off, the main contactor
release is generated and the main contactor is switched on by the function module BM4-
F-SEA-XX (to slot C). The monitoring signal of the main contactor is transmitted by the
function module BM4-F-SRM-XX (to slot B) to the controller. Then the message „Ready-
to-operate drive“ is generated via the function module BM4-F-DIO-01/02 (digital I/O to slot
D).
For synchronization and mains voltage monitoring a function module BM4-F-UME-01 is
used.
The controller unit controls the power unit and all functional modules. You can operate
the controller part either with the operating software ProDrive (PC) or via a SPS (BM4-O-
PLC-OX), which is deliverable as an option module.
4.2 Controller unit variants
There are two variants of the controller unit:
1-rowed
2-rowed
This variant is a 1-row equipable
controller unit in a 2-rowed installa-
tion space. This controller unit is
available for every BM4100.
This variant is a 2-row equipable
controller part in a 2-rowed instal-
lation space. This controller unit is
available for every BM4100.
