4.6 Connection of the supply voltages
Power is supplied to the axis controllers separately for the control section and power
section. The control section in the axis controller receives its 24 V supply from the supply
unit via the upper busbars (+24V DC and GND).
The power section in the axis controller receives its DC link supply from the supply unit
via the lower busbars (DC Link+ and DC Link-).
Step Action Comment
1.
First make sure all KeDrive D3-DA axis controllers BG3 and BG4
are arranged in a line with the KeDrive D3-DP supply unit BG3
and BG4 and they are together in a row.
See installation instructions in
Figure 3.1.
2.
Always connect rst the 24 V control supply
for the axis controllers.
If you want to use several axis controllers, all 24VDC
connections and all GND connections must be connected
together.
For this purpose use the pre-
assembled busbar elements as
per Figure 4.9. It is necessary to
unscrew the screws slightly to be
able to rotate the busbar elements.
3.
Only connect the DC link supply when you want to place the axis
controllers in operation.
If you want to use several axis controllers, all DC-Link+
connections and all DC-Link- connections must be connected
together.
For this purpose also use the pre-
assembled busbar elements as per
Figure 4.10.
4.
Once all busbar elements have been tted, the screws must be
re-tightened!
CAUTION! Risk of injury due to incorrect wiring!
Carelessness may result in injuries.
Make sure that all connections have good contact and are sufciently secure that they cannot
come loose. If connection elements are used that do not meet the requirements, KEBA does
not provide any guarantee for stable, reliable operation.
