Max. cable lengths according to EN 61800-3 for servo drives AX5101 - AX5140
With longer motor cables the resulting commutation currents can lead to EMC interferences. Use the tables below to check whether mains chokes or mains filters have to be used in your application. When selecting the control cabinet ensure that there is adequate space for mains chokes and mains filters, etc.
Lay the power and signal cables in separate metal cable channels or, if both types of cable use the same metal cable channel, make sure there is an grounded metal divider panel between the cables.
 | Motor chokes For the AX5140 to AX5193 series no motor chokes are required. |
Maximum cable length (including extensions) for a nominal motor voltage up to 400 V:

1)For compliance with EN 61800-3 only with mains filter AX2090-NF50-0014.
2)For compliance with EN 61800-3 only with mains filter AX2090-NF50-0032.
3)C3 with up to 70 m without mains choke possible for devices with order number AX5140-0000-1202.
In exceptional cases (sensitive sensors, etc.) it can be necessary to use a motor choke even for motor cable lengths < 25 m.
Maximum cable length (including extensions) for a nominal motor voltage up to 480 V

4)Please talk to our application department.
In exceptional cases (sensitive sensors, etc.) it can be necessary to use a motor choke even for motor cable lengths < 20 m.
To keep line perturbations (distortion reactive power) as low as possible, a mains choke should always be used.

Radio interference in the living area: Mains chokes are products with restricted availability according to EN 61800-3. The products may cause radio interference in the living area. In this case, necessary measures must be taken by the operator. |
