Total motor cable length
In compliance with the EMC category C3, various total motor cable lengths apply to the AX8000 multi-axis servo system.
Without mains choke
Motor cable length | Total motor cable length | Number of axes per drive system |
|---|---|---|
Maximum 25 m* per motor | Maximum 300 m per drive system | Limited by the maximum chargeable DC link capacitance and the 24 VDC supply with a maximum of 20 ADC The requirement is determined via the module current and motor braking current. |
With mains choke
- Mains choke to be used: AX2090-ND80-xxxx
Motor cable length | Total motor cable length | Number of axes per drive system |
|---|---|---|
Maximum 100 m* per motor | Maximum 500 m per drive system | Limited by the maximum chargeable DC link capacitance and the 24 VDC supply with a maximum of 20 ADC The requirement is determined via the module current and motor braking current. |
*) When using cable lengths of individual axes greater than 15 m and a supply voltage greater than 400 VAC, the motor cable length actually used (here 22 m) must be entered in TwinCAT 3 Drive Manager 2:
