You're probably reaching your vfd's current limit or the motor speed is too low. I suggest to check the current and also consider using a reducer gearbox or pulleys.

The 4M may not be enough drive for this. See this tech note (access level: everyone):

You may need to register for a free account to read it.

You may also be able to install a sort of dancer arm or tension measurement (like a load cell?) to serve as a speed trim to the drive.

Hi just a quick update if anyone out there is looking at this and wants to run a 4M inverter the way i do change parameter A453 that's set at factory default 8  to 1  this will allow the motor to stall and not go into fault mode

Because of your name... My daughters went to Coastal Carolina University, and their mascot is a Chanticleer...

Hi Armadillo852,

I visited the CCU link. Very nice story and very interesting character (this Chantecleer)

I borrowed the name from a movie I watched with my children years ago called Rock-a-Doodle

I think the movie was based upon an Edmond Rostand’s play called Chantecler

Edmond Rostand is better known for his Cyrano de Bergerac

Bye
