DC Bus link (X3, X14)
The DC bus link can be connected in parallel so that the regen power is divided between all the
drives that are connected to the same DC bus link circuit. Every drive must have its own power
connection to mains voltage, even if the DC bus link is used. Drives working generatively very often
should be placed beside drives, which need energy. That reduces current flow on longer distances.
For fuse type definition refer to (
•
The sum of the rated currents for all drives connected in parallel to an IC830DP003 to 024
•
must not exceed 48 A. Examples: 024-024-024, 012-012-024-012
•
Use 6 mm², unshielded single cores with a max. length of 200 mm; use 6 mm² shielded
cables for longer lengths. In this case no fuse for line protection is required.
•
Use 16 mm², unshielded single cores with a max. length of 30 mm; use 16 mm² shielded
cables for longer lengths.
Note: Drives can be destroyed, if DC bus link voltages are different. Only drives with mains supply
from the same mains (identical mains supply voltage) may be connected by the DC bus link.
Note: The phase lost/ main control is not working on DC-Bus connected drives. A phase lost on a
drive inside a DC Bus connection will be not detected. External phase monitoring to prevent
overload of the rectifier is recommended.
