F31121 Encoder Frequency Too High fault in siemens drive

-
F31121 Encoder Frequency Too High fault in siemens drive indicates that t he input frequency from the encoder exceeds the maximum capability of the encoder interface (SMC/SME module).   Cause   1. Motor speed too high for the encoder resolution. 2. Encoder cable interference (noise).   Remedy   1. Reduce maximum speed.  2. Use an encoder with lower pulse count per revolution.  3. Check shielding.
