Similar to the KLC, the V1K is designed for use on modern PWM drives with a diode front end power structure. While being the latest in drive technology, these fast switching electronic drives have been found to produce a high amount of dV/dt or voltage distortion on the output voltage waveform. To operate the drive and motor properly, we recommend the drive carrier frequency be adjusted to 8 kHz or less and the drive be operated at an output frequency of 60 Hz and lower. The manual can assist with the other system considerations required.
