Hello,

I am using a 6RA80 Dc drive. I want to run the motor at an increased torque for sometime. Is that possible?

Hello,

How much % torque user want to increase & how much time? Do you have load cycle? If yes you may define load class in p50067. Please refer attached sheet for more details.

But how can I meet my requirements setting through p50067? In that case, will the speed be same?

 if u have choosen the right load cycle and your Power Unit is big enough to deliver the torque and other parameters like max Current are set right, then yes.

And i really dont understand your bad rating, i gave you the answer you wanted to hear, u did not ask how to get to the point, u asked if its possible

 Hello,

Normally if motor & drive selection is correct then with standard parameter setting like 100% current setting & 300 % torque setting values the speed requirement is met. (Here I presume drive is 4Q)

However speed precision requirement depends upon type of feed back device couplied & interface to drive. In case of drives with analoge tacho & analoge set point 0.1% rated motor speed close loop control & with incremental encoder & digital set point 0.006% rated motor speed close loop control can be achieved. 

If you have specific application demand, you may select technology option modules.

So What is your application?
