Hello!

I have some old stuff here. 3 kind of Simoreg from Siemens C98043-A1054-L3 and C98043-A1054-L4. I do not have any documentation about them. What I need to know is what the potentiometers R1, R2, R3, R4, R169 and R170 are used for.

Thanks in advanced!

Best regards!

Your Drive appears to be of 6RA22 series. R1..R4 are the burden resistors for the current transformers. Their value defines the DC Current rating of Simoreg. R169 and R170 are probably the potentiometers for Coarse and Fine adjustment of speed feedback through analog tachogenerator.

Complete manual is available in the archives section on Siemens Website for support.

Hope this helps you.
