Electrical installation

WARNING

Avoid contact with DC link DC+ and DC-

Measure the voltage on the DC link test contacts DC+ and DC-. Observe the waiting times after disconnection from the supply network:

    • 30 minutes for AX8620 and AX8640
    • 30 minutes for AX8108, AX8118 and AX8206
    • 30 minutes for AX8525 and AX8540
    • There is still a life-threatening voltage of > 875 VDC on the capacitors after disconnection from the supply network. Serious or even fatal injuries may result if this is ignored.

    Notice

    Damage due to improper grounding or faulty contacting

    Improper grounding or faulty contacting can lead to damage to the connected multi-axis servo system or to EMC interference emissions. The minimum cross-sections of separate protective conductors can be found in DIN EN 61439-1.

    • Establish a conductive connection of all components
    • Only use shielded cables
    • Ground the shields of the pre-assembled cables via the mounting plate and place the star point centrally on the unpainted mounting plate
