hi everybody,
I have a small problem with a powerflex 700 S2 Drive in conjunction with 2 encoders (2nd encoder option card is mounted).
encoder 0 is mounted on the shaft of a conveyor
encoder 1 is mounted on the main motor of a machine.
The goal is to run the conveyor with exactly the same speed as the main motor of the machne.
I had everything mounted in my office for testing and all worked fine (autotune etc.). I tested the system with a drilling machine (encoder 1) and encoder 0 mounted directly to the test drives shaft. as already said, all worked excellent.
Now i am on site and have a problem.
encoder 0 is now mounted on the shaft of the conveyor (not the motor) with a gearbox between.
Autotune now fails because the speed feedback is not correct (this is true, it is of by the gearbox ration (ca. 5.2 Factor)).
I cannot find any way to tell the powerflex 700 Drive to multiply the encoder signals with about 5.2.
encoder 0 is configured as Speed Feedback Signal Primary
encoder 1 Speed Signal is linked to Parameter 10 (Speed Signal).
Is there any way to fix this ?
thank you in advance
greets
