Absolute position missing

Dear Sir,

I have issue of  absolute position changing while repowering the servo drive with following hardware.

PLC        :  S7_1517F-3 PN/DP

Drive     :  6SL3210-5FE11-0UF0

Motor   :  1FL6044-1AF61-2LB1

I used technology object  with TO Positioning Axis configuration, technology blocks and Telegram 3.

MC Home with mode 7, after homed the axis while turning off the power then turning  ON the Servo drive power

Axis losing its actual position randomly.

I tried Cyclic Absolute type in TO configuration but the program not downloading to the CPU, I have attached that

Error snapshot.

For your reference please find the attached snapshots of TO configuration parameters and Servo Drive backup fyl.

Hey there!

Best you check this FAQ: https://support.industry.siemens.com/cs/de/en/view/84133347
It shows all the possible reasons and describes where to look at.

Most importantly ensure that you check the preconditions for enabling the technology object with MC_Power, as described in the other FAQ that is linked there.
