encoder:DZO_2048_SR
it has been provided with encoder:ERN 1381.020-2048 ID:385489-06,MAKE:HEIDENHAIN


THE EXISTING MOTOR IS HAVING THE ENCODER ERN1381.062-2048 ID:727222-07 ,make:heidenhain

THE DRIVE FOR THE ABOVE MOTOR IS MASTER DRIVE :
SIMOVERT VC 6SE7032-6EG60-Z

Now,
1.what exactly the difference between the above two encoders?.
2.can I use ERN13381.062 inplace of ERN1381.020?
3.what is the difference if I use EQN1325 inplace of ERN1381.020?what is the difference? -only absolute and incremetal or ???

"external encoder) was incorrect for one or more samplings. This can result from EMC

faults or a loose contact. When faults start to occur at a certain rate, fault message F51 is triggered by thecorresponding fault variable". Though there is no tripping , but why it is coming. will it be due to encoder problem?.the encoder which I have replaced is new one.

New question published by khann is split to a separate thread with the subject What is the difference between H7 and F7 from ERN 1381.020?.
