Functioning
Basic unit
The present alternating voltage at the three-phase system is converted into direct voltage
by the input sided rectifier. The DC link capacitors smooth this DC link direct voltage. The
output sided inverter generates a three-phase system from the direct voltage with variable
frequency and voltage for the supply of the connected motor.
Additionally you can draw d. c. from the device via the DC link connections.

are universal converters, for achieving electrical drives in industrial applications.
BM4400 offers the largest configuration possibilities as well as the most available options.

(acceleration units) are especially developed servo drives derived from BM4400
for acceleration applications. Characteristic for these devices is, that the peak current is
twice as large as the rated current, even at large output currents. The devices were de-
veloped for a cycle, which could provide the peak current for 1.25 s at a whole cycle du-
ration of 5 s according to
This units are not developed for peak current using at standstill or output frequencies low-
er than 10 Hz. For this units the

(continuous current units) are servo converters especially developed for main
drives, derived from BM4400. The devices were developed to maximize the available rat-
ed current by water cooling. For this reason these devices are only available with water
cooling (cooling type -F and -Z) and with none peak current (only BM5773 with low peak
current).
Controller unit
The power unit is controlled by the controller unit. You can operate the controller part ei-
ther with the operating software WinBASS II (up to FW 3.09) or ProDrive (from FW 3.07)
or via a PLC or via a field bus and PLC.
NOTE!
Only the operation with ProDrive is described. If the software is not available, please
