B.4.1 EMC compatibility and motor cable length
The following table describes the maximum motor cable lengths that meet the requirements of the EU
EMC directive (2004/108/EC) when the carrier frequency is 4 kHz.
All models (with external EMC filters)
Maximum motor cable length (m)
Environment category II (C3)
30
You can learn the maximum length of the motor cable through the running parameters of the VFD. To
understand the accurate maximum cable length for using an external EMC filter, contact the local
TECHTOP office.
For description about the environments categories I (C2) and II (C3), see Section B.6 "EMC
regulations".
