Hi, everyone. I have The Sinamics G120 drive. My problem is that after downloading new configuration into the drive, i recieved error A7991: Motor identification is activated, and LED RDY is slowly blinking with GREEN light. I found some tips on this forum - how to get rid of the error A7991.(Actually, i just changed P1900 parameter from 2 to 0, and the error disappeared). But LED RDY is still flashing slowly. 

Can someone help me and ask what is RDY GREEN FLASHING means? And can you give me some instructions, tips or manual how to get the drive out of this state? 

Very appriciate your help.

Hello,

if the RDY LED is blinking green it usually means that the drive is in commissioning mode.

How did you commission the drive? With Starter / Startdrive commissioning tool or with BOP/IOP panel? Did you go through the commissioning wizard (quick setup)?

Did you enter the motor data and tried to run the drive? Does anything not work properly?

hello sir,

after change the parameter from 1 to in 0 in P10. it is working but when emergency p/b pressed or turn drive power off again same problem. ready LED blinking.

Is there any problem in CU. as our drive was running smoothly  before this problem.

Have you saved parameter in ROM after changing?

After changing any parameter, save it in ROM so that it will be permanant even in case power is switched OFF.

If using STARTER, click on RAM to ROM button, if chaning from BOP set p0971 = 1, after changing parameters, this will copy & save parameters in ROM & after completion/saving p0971 will be set to 0 automatically.
