ACS601 : how to regulate the "resistive torque" by acting on speed ?
Bonjour,
I have an ACS601 on a machine.
On this machine the "resistant torque" varies with speed and with the filter dirt rate.
When the resistive torque increases because of the filter, i want the speed to decrease to keep the resistive torque at its initial value.
How to make ?
For now I've set the settings 40.14 on PROPORTIONAL and 40.18 on SPEED TRIM but i don't know how to give the correction to the speed...

Hi,
Without to know in details your settings and mode of operation of the drive, I can recommend to look in 20.04 torque limit.
Or parameters 32. Here you can define the torque limits 32.7...32.10 or current limits 32.5...32.6.
These are fixed settings and when the corresponding limit is achieved, you can use RO1,2,3.
Or torque control macro.

In addition to Kolyo's answer, you can try to use a Droop Rate parameter . This is a simple function that helps to relieve some motor load by decreasing the motor speed on high motor torque.
however Droop function is not an *exact* tool in terms of Torque limit. Its tuning is like a try and error. Try to set 1 ... 5 %.
I have used it on brushing machine of steel strip.
