I am trying to make a shredder, but I am having problems with the VFD.
The motor is connected to a relatively small plastics shredder blades via a gear box.
If I attach it directly to 3-phase 380V, it shreds the material without hesitation.
The current clamp says it uses about 1.5-2A while doing so
However, when I use a VFD and throw in the material, the motor will slow down and stop completely.
No error codes, it just stops and the VFD puts out a steady 3.5-3.8A.
The VFD's I have used are:
-V70-1.5S2 (1.5kw)
-YL620-A (2.2kw)
These are the motor specs:
I have set all the parameters (frequency, voltage, current etc) to the correct amount or even higher.
But no results. The only thing that gives somewhat of an improvoment is setting control mode from 'vector' to 'vf'.
What could be the cause? Or better: what could be the solution
