DC bus link (X0)

Can be connected in parallel, thanks to patented circuit to distribute the regen power among all the
amplifiers connected to the same DC bus link circuit. (Connection example ð p. 89).
Only servo amplifiers with mains supply from the same mains (identical mains
supply voltage) may be connected by the DC bus link.
The sum of the rated currents for all of the servo amplifiers connected in parallel
to an AX2040/2070 must not exceed 300A.
Use unshielded single cores (>=10mm²) with a max. length of 500 mm. Use
shielded cables for longer lengths.
