Turn the switching frequency P1800 down to a low value, 2 kHz I believe is the low value. Have seen this on site myself. If you look ‘close’ at the specification this is correct.. From the attached, the current will limit at 143.5 Amperes, whilst operating at 4 kHz, at 2 kHz it will provide the full rating. I initially thought this was a product defect, working with an Engineer from one of our Utilities, we were getting a bit anxious on site as the 'product' was backing up........... I was pleased to find the 'de-rating chart', attached. AttachmentSwitching frequency derating.pdf (539 Downloads) |

It worked! I am really surprised by the derating for this drive. Thanks a lot! Regards, Predrag |
