3.3.3 Requirements to the control voltage / 24 V-supply
Figure 6: Control voltage / 24V-supply
The power supply for the 24 V supply voltage must provide the rated power, at least,
which accords to the sum of the 24 V-supply voltage of all devices.
3.3.4 Requirements to the motor
The BM3200, BM3300 was prepared for the operation of three-phase motors with a mo-
tor terminal voltage of 3 x 350 V (typical for servo motors of Baumüller) or 3 x 400 V (typ-
ical for standard asynchronous motors and for customer-specific special motors of
Baumüller). The motors are to be operated wye-connected. The rated DC-link voltage is
540 V
DC
. In braking operation it must be expected, that the DC-link voltage increases to
780 V or 800 V. The connected motor must be constructed for these DC-link voltages.
The use of the devices is also possible at smaller voltages, e.g. 3 x 230 V. However, this
implies that the used three-current motors for the operation at inverters with a voltage of
up to 800 V DC-link voltage are designed, because the ballast resistor voltage threshold
remains unchanged (see ZElectrical data– from page 35). Thus, in these cases, three-
phase motors with U
DC rated
540 V, must be used, only.
