3.2.2 DC bus coupling, DC supply
3.2.2.1 DC bus coupling
It is possible to couple multiple servo positioning controllers of the item C 1-Series when they have the same DC bus voltage.
For this purpose, the PFC stage has to be deactivated
Caution!
DC bus coupling is not allowed while the PFC stage is active. This can otherwise result in damages to the
servo positioning controller.
Caution!
When the DC buses are connected, the power supplies must be connected to the same mains phase.
This means, if two C 1-05 are coupled in the DC bus, only the connection L1/N is possible for both devices. It
is not allowed to connect the DC Busses if the devices are connected to different mains phases.
It is forbidden to supply device 1 via L1/N and device 2 via L2/N, when the DC buses are coupled.
Caution!
Operation with DC bus coupling together with devices of the item C 3-Series is not allowed.
3.2.2.2 DC supply
The direct DC supply is supported for a supply with voltages ≥ 60 VDC by the DC-bus connection instead of the connection to
the mains
The digital motor temperature measurement system requires a DC-link voltage of
120 VDC minimum. Below this voltage, the system will always identify the digital motor temperature sensor as
open.
3.2.3 Mains fuse
A slow-blow (B16) single-phase automatic circuit breaker of 16 A has to be installed in the mains supply line.
