I 'm not getting any EMF feeedback on DCS 800
I have primary dcs 800 on line with a Hot spare. When we switch to the spare I'm not getting any EMF feedback. M1SpeedfbSel is set to EMF in parameters. A constant 87 rmp is showing on upper right corner if HIM. Any ideas on why? I did not commission drives. Just trying to figure out why we can't get this feedback.

Does the motor run with the spare?

Hi,
Here below is the EMF path if you use it for feedback (from FW Manual).
So you have to check all involved parameters (99.02, 99.04, 50.03, 50.06, 50.17).
You can supervise the path by corresponding signals (1.02, 2.29, 1.04, 1.41)
If you have already one working identical drive, you could check the parameters first with it.
