8.8.2 Mains supply connection (X0)
— EMI filter and mains choke (required) provided by the user
— Fusing (e.g. fusible cut-outs) provided by the user ð p. 22
8.8.3 24V auxiliary supply (X4)
— Electrically isolated, external 24VDC supply, e.g. with insulating transformer
— Required current rating ð p. 21
— Integrated EMI filter for the 24V auxiliary supply
8.8.4 DC bus link (X0)
Can be connected in parallel, thanks to patented circuit to distribute the brake power among all the
amplifiers connected to the same DC bus link circuit. (Connection example ð p. 91).
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 SERVOSTAR 640/670 must not exceed 300A.
Use unshielded single cores (>=10mm²) with a max. length of 500 mm. Use
shielded cables for longer lengths.
