just looking at the maunal, pffff looks mega complex
The usable range is 6k to 24k rpm. Go much below 5k and there is no torque without playing with VFD settings.

The settings for acceleration and de-acceleration are PD14 and PD15. Set to 5 and 10 respectively, don't go too low on the acceleration otherwise, you will get over current/voltage error's as the VFD dumps loads of current/voltage into the spindle trying to meet the request to get upto speed in the short time period.
