Turret Refernce Problem

I have CNC Lathe Machine TORNADO T10M. The machine is provided with GE FANUC Series 21i-TB and servo amplifier A06B-6093-H152 .
Few days ago, the battery of machine drained completely. The battery has been replaced but machine has lost reference and following alarm appeared.

1017 Turret drive alarm 224The servo amplifier unit shows blinking “U” AND “11” in seven segment display.

During normal operation , this machine does not require reference when powerup

Parameter 0011 is not available in the panel as you can see in the video.



Need urgent help
Thanks in advance.
