840D Safety Integrated Error 27004

It is coming up with the following error for the spindle drive, 27004,27101,27102, and 300911. All of the troubleshooting guides recommend cycling power off then on. We have repeated this several times with NCK reset and complete power down of the system and power on. This has not resolved the issue. Any thoughts on how to resolve this issue? Thanks in advance. Jerry

After starting this thread, I went to the machine and found that there was another alarm for the z axis encoder parameterization. I fixed this issue, and turned off the DB35.DBX22.1 bit for the spindle. This allow the machine to power up, reference and home. Thanks for the feedback! Jerry
