Dealing with Motor ID ( code 7991 )

• Is any bit in communication between plc and sinamics informs inverter need Motor data identification? If yes, I can automatically perform measurement by disable/ enable inverter and run motor till it measured, next to switch to normal operation
• Do You have idea why motor stop working after feature switched off?
• If an example motor have 1405 rpm. Should I write in Rated motor speed (p311[0]) 1405 or 1500?

Thanks in advance.

Hello,

Set p1900=0 it will deactivate motor identification.

Set p0311 = 1405. It calculates motor pole pair.
