Trouble with Configuring Kinetix 5700 Dual Feedback

1 post in this topic

Hi everybody.

Im struggling trying to configuring a kinetix 5700 servo running in dual feedback mode.

The drive is a 2198-D032-ERS3.
Motor type is VPL-B1304E-P
Load Feedback sensor is a Magnetic incremental linear encoder. Reading at a "magentic tape" with Resolution 0.01 mm  (at 4-edge triggering) and Repeat accuracy ± 0.001 mm.

I´ve set this one up as
Type: Digital AqB
units: Meter

Cycle Res: 25000
Cycle Interpolation: 4
effective Resolution: 100000

In Scaling ive calculated the Ratio in the transmission section. So if i go with motor feedback only i manage to go to position +-0,15mm at a range of 9000mm.
So i think that is set up correctly.

But when I try to go with Dual feedback for more accuracy. I can only enable the axis and execute mam instructions when the actual position is inbetween -1000 and +1000mm. If I´ll go further the axis faults and tells me Excessive position error.

Ive got value in positionfeedback1 and 2. Positionfeedback2 is the same as actual position but with "decimals" So if actual position is 950.20 the feedback2 tag says 95020.

Does anyone here experience the same issue? Any thoughts please feel free to reply!

thanks in advance. /A
