When you grab the pully the motor will stop running, so there is no current and the magnetic field will be stopping and there is no overload. Is this the advantage of using Sensorless Vector Control or torque control than V/H mode ?
Not in this case. The CFW500 does support some vector modes that will utilize encoder feedback. This is a sensorless vector mode so it utilizes real time electrical feedback from the motor leads to allow the drive to target precise speed and torque at nearly any frequency.
@murilomotta5038, in most printer unwinder applications we would recommend a servo for much faster response time to the torque loop in the material tensioning. This drive can be used for tensioning applications in firmer stronger materials (like taking up belt tension in a flexible tension situation for a conveyor) but take a look at our SureServo 2 or LS servo options with torque mode for much better response in unwinder applications with sensitive materials that are more prone to tearing. You are also welcome to try this drive in that application. We offer a 45-day free return policy for situations just like this, just make sure to save all the original packaging. www.automationdirect.com/adc/shopping/catalog/motion_control

Sensorless vector is great for those times when you more accurate control over your motor but don't have an encoder to do it.
In this case, are you using econder or not??

@@automationdirect In this case, can it be used as a printer rewinder? As soon as the operator stops the machine, the material is tensioned
