Which parameters are important to commission servo spindle?

Dear all

I  am having a problem with servo spindle. When I press Jog key (from MCP) , the spindle start with a jerk, then stop eventually and produced a drive alarm F7900 on servo drive. If I press a reverse spindle command it first try to rotate opposite direction and  then it try to rotate commanded direction, for this reason it produced a shock and then stop with alarm F7900 on the drive seven segment display. This whole things happen within a second. Also I am getting alarms on CNC screen are 021612 & 025201. 

During the drive configuration I have only option for motor ID 20001 but my spindle motor ID is 20004. I have no option for configuring my ID 20004 motor.  I have checked my encoder cable, motor shaft for checking it can rotate freely and encoder pulse. 

But I have not checked the motor  torque limit  & inversion of the actual value [ Please clarify this two parameter as I am not familiar with this two]

I have set the parameter 32260, 32000, 26200, 31050, 31060.

Before this new setting the spindle was working fine.

Please help me  to solve this issue. Please clarify which parameters are important to commissioned servo spindle.

Kind Regards

Split from Sinumerik 808d spindle speed.

Hello.

Please add the part numbers for the hardware you are trying to implement.

If I understand correct this is a Sinumerik 808D system?

What drives, what motors, and how is it connected?

Also what PLC did you use? The default one?

I have solved this issue. The problem was like I have not checked the phase sequence between drive and motor.

Thank you for your reply.

Kind regards
