Replace motor

Hi all,

I need some help about replacing  servo motor. We use 1KF7063-5AF71-1KB3 compact motor in a welder machine, the encoder type is A32S/R. Our spare motor type is the same, but the order number start (1P) like this: (1P) 1KF7063-5AF71-1KB3 and the encoder type is AM16DQ K60.

My question is that the two type is really the same, because the motor doesn't work. When I connect to the drive by STARTER, I find the following fault in the alarm list: encoder serrial communication error. I tried to identify the encoder automaticly and read the encoder serrial number then download to the target CU but still not working and I restart the CU unit several times.

Maybe I have to re-read the motor ID somehow?

Hello,

How or where from you derived mentioned encoder details?

If the encoder details A32S/R you provided assumed to be correct, then motor MLFB number would be 1KF7063-5AF71-1GB3 & not 1KB3. This motor is without Drive-CLiQ encoder interface.

1KF7063-5AF71-1KB3 motor is with Drive-CLiQ encoder interface & encoder is 16 bit absolute encoder single-turn +12 bit multi-turn.

So both motors encoders are not equivalent & I am surprised as how you connect or replace it. 

Please refer attached sheet for more information.

HTH.

I derived the  encoders details from the motors nameplates.

- The built-in motor: 1KF7063-5AF71-1KB3, encoder: A32S/R

- The new motor: (1P) 1KF7063-5AF71-1KB3, encoder: AM16DQ K60

I will check the nameplate again and take pictures from it next time.

Maybe we got a wrong motor because AM16DQ K60 details are:

Absolute encoder 16 bit (resolution 65536,
internal 32 S/R) + 12 bit multi-turn
(traversing range 4096 revolutions)

Both motors have two connection point, one Drive-CLiQ and one fast connection for supply and brake.

G is for A32S/R without Drive CLiQ encoder interface 

K is for with Drive-CLiQ encoder interface & encoder is 16 bit absolute encoder single-turn +12 bit multi-turn.

Motor MLFB number will never be same for two different types of encoders.

Please refer attached sheet in earlier post.

Pretty simple to tell the difference.

If it is a DRIVE-CLiQ encoder, there wit be a connection for an Ethernet looking cable.

If it is a standard encoder, there will be a multi-pin circular connection.  Which do you have?

I have both types of connector. I've checked the nameplates on the motors again and the mentioned motor types are correct, 1KF7063-5AF71-1KB3 but i have different encoder types.

 You can't have both.  They have power connections and encoder connections.  The power connections have big pins.  Encoder connections have lots of little pins and are at the rear of the motor.  If you have a DRIVE-CLiQ encoder, it will have an RJ-45 looking connector along with the power connector.

Both motor have one power connector with big pins and one RJ-45 looking connector....

here is the photo from the motor name plate.

....1KB3 and I have AM32 S/R encoder not AM16DQ as the K indicates in the catalog....
