GD310-UL series VFD Technical data

B.2.2.2 Altitude derating
When the altitude of the site where the VFD is installed is lower than 1000 m, the VFD can run at the
rated power. When the altitude exceeds 1000m, derate 1% for every additional 100m. When the
installation site altitude exceeds 3000m, consult the local INVT dealer or office.
B.2.2.3 Carrier frequency derating
For Goodrive310-UL series VFDs, different power level corresponds to different carrier frequency
range. The rated power of the VFD is based on the factory carrier frequency, so if it is above the
factory value, the VFD needs to derate 10% for every additional 1 kHz carrier frequency.

B.4.1 EMC compatibility and motor cable length
To comply with the European EMC Directive (standard IEC/EN 61800-3), use the following maximum
motor cable lengths for 4kHz switching frequency.
All frame sizes (with external EMC filter) Maximum motor cable length, 4kHz
Second environment (category C3) 30
First environment (category C2) 30
Maximum motor cable length is determined by the drive’s operational factors. Contact the local
representative for the exact maximum lengths when using external EMC filters.
