Not tested.
Sine filters further extend the cable lengths.
WARNING! Using a motor cable longer than specified in the table above may cause
permanent damage to the drive.

Check operational limits for R1 and 8 kHz -> for a 150 m (490 ft)
cable a du/dt filter is needed.
Check EMC limits -> EMC requirements for Category C2 are met
with a 150 m (490 ft) cable.
Check operational limits for R3 and 4 kHz -> a 300 m (980 ft) cable
cannot be used even with a du/dt filter. A sine filter must be used and
the voltage drop of the cable must be taken into account in the
installation.
Check EMC limits -> EMC requirements for Category C3 are met
with a 300 m (980 ft) cable.
Check operational limits for R5 and 8 kHz -> for a 150 m (490 ft)
cable the basic unit is sufficient.
Check EMC limits -> EMC requirements for Category C3 cannot be
met with a 300 m (980 ft) cable. The installation configuration is not
possible. An EMC plan is recommended to overcome the situation.
Check operational limits for R6 and 4 kHz -> for a 150 m (490 ft)
cable the basic unit is sufficient.
EMC limits do not need to be checked as there are no EMC
requirements.
