Dear PISCEAN,

* When I change P0491 with 5, Can the p1300 change with 20 automatically?

Hello,

Please check value of p1800 i.e. pulse frequency, it must be > 2KHz. So when you set p0491 = 5 & when BO status signal r1407.13 = 1 i.e.  encoderless operation due to fault, a different data set is selected which is same as original data set e.g. p1300 = 21 (which is in your case) & encoderless closed loop controlled operation is kept. You can check the selection of different drive data set selection by checking p0820 interconnection in your project.

Hope this helps.

Hello,

p491 = 5 were added in firmware v4.4. Maybe you have lower firmware version, try to upgrade at least to v4.4. If you have 1st generation Sinamics drive (firmware v2.x), it is not possible without changing drive hardware.

With regards
