I think we need a way to increase start voltage/amp or torque at <1hz, i dont think SVF mode is quite tuning properly and needs some manual adjustment. There are quite a few settings in the manual related to this which i am going through. I have also contacted driveswarehouse where i bought my 015SF's for support so hopefully can get some advice there.
Its also why fabi's autotune wont work for me as the flicking of the motor is causing havoc with the osciliscope readings (despite no interference on the pot signal)
What i think is happening is the motor is stalling at <1hz due to lack of power which is creating the jitter as it tries to start. tronicgr Thanos have you come accross this issue before, does it sound like im on the right track?
Thanks.
EDIT: don't know why I didn't try this sooner, switched vfd to panel control and tested low frequencies direct from the panel to take everything else out of the equation.
The motor runs fine at very low hertz eg: 0.2 without any jitter. So assume this is a noise, amc or PID issue??
