encoder feedback Fail

Hello,

Actually I am commissioning one 3.7 kw motor with 9 kw sinamics Siemens drive with Hubner 1024 pulse(OG9D) Encoder.there is one problem:when I put the drive in with encoder(p1300) and try to run ,the encoder don’t give every pulse and in “stationary measurement give 7982[5] fault.and when I run the motor from control panel directly give 7900 & 7902 fault with out every encoder pulse.How can I fix this problem?It must be mentioned that Encoder,SMC30,drive cliq cable and … is checked and are healthy.in the starter project ,also I put the drive in close loop control (with encoder )in commissioning).

Best regard

 give more information, order numbers...

Power Module - ???

Control Unit - ??? 

Hubner encoder - TTL or HTL? how did you connect it? homemade cable or original?

Сan you check the encoder, is healthy? Do you have another encoder and SMC30?

Hi,Dear

Actually encoder is HTL,Unipolar,drive model is : 6sl3120-1te21-8aa3 and SMC30=6SL3055-0AA00-5CA2.and control unit=cu320,6SL3040-0MA00-0AA1.

encoder cable is original.

The SMC30 & encoder are replaced with a new one ,but pulse also is not coming.

Hello,

at unipolar encoders the inversion tracks (A/ and B/ ) has to be connected to mass. This is described in manual GH1 (see SMC30).

First I would run in sensorless mode and compare r63 with r61. If r61 would be negative to r63 you have to change the A/B- tracks on SMC30 OR change it by parameters (See p410ff).

If the speed value does not fit (for example factor 2 smaller / higher)  the pulse number is incorrect.

i think you are not getting the encoder valve (LU)
