The PLC is an S7 1500 v3.0, and the drive has been updated to FW v6.3. The motion control has been configured with the positioning axis Technology Object. The drive loses the actual position of the motor during a power cycle or communications failure with the drive. Homing is performed with MC_Home Mode 7. I have noticed that the actual encoder online value (Gx_Xist1) Does not retain through the power cycle. Also if a mode 7 home is performed, and the motor is not moved from the homed position, the actual position will be retained through the power cycle. Any help is greatly appreciated. Attached are images of the encoder config in the TO. Attachment S210 Encoder Config - Google Docs.pdf (283 Downloads)

Your increments per revolution are too high. For a multiturn encoder this should be "4096". Nervertheless you can have a look at following FAQ: https://support.industry.siemens.com/cs/ww/en/view/84133347 Otherwise I think you should create a support request.
