DC bus link (X8)

Terminals X8/1 (-DC) and X8/3 (+RBext). Can be connected in parallel, whereby the
brake power is divided between all the amplifiers that are connected to the same DC bus
link circuit.
The servo amplifiers can be destroyed, if DC bus link voltages are different. Only servo
amplifiers with mains supply from the same mains (identical mains supply voltage) may
be connected by the DC bus link. Use unshielded single cores (2.5mm²) with a max.
length of 200 mm. Use shielded cables for longer lengths.

*HWR = Hardware Revision (see nameplate)
SERVOSTAR 303-310:
The sum of the rated currents for all of the servo amplifiers connected in parallel
to an SERVOSTAR 303-310 must not exceed 24 A.
SERVOSTAR 341-346:
The sum of the rated currents for all of the servo amplifiers connected in parallel
to an SERVOSTAR 341-346 must not exceed 40A.
