Code 25022: Axis %1 encoder %2 warning %3

Parameters: %1 = Axis name, spindle number %2 = Encoder number %3 = Error fine coding Definitions: This alarm only occurs with absolute encoders: a. Warning notice of missing absolute encoder ad justment (on the SIMODRIVE 611D or with PROFIdrive drives), that is if MD34210 $MA_ENC_REFP_S TATE equals 0. In this case, fine error code 0 is returned. b. If, on the SIMODRIVE 611D only, zero mark monitoring has been activated for the absolute encoder (see MD36310 $MA_ENC_ZERO_MONITORING): In this case, the absolute position of the absolute encoder could not be read without error: Breakdown of fine error codes: (Bit 0 not used) Bit 1 Parity error Bit 2 Alarm bit of the encoder Bit 3 CRC error Bit 4 Timeout - start bit fo r EnDat transfer is missing This alarm is only displayed, as t he absolute position itself is not requi red at this time for control/contour. A frequent occurrance of this alarm indicates that the absolute encoder transfer or the absolute encoder itself is faulty, and that an incorrect absolute value could be determined in one of the next encoder selection or power on situations. Reaction: Alarm display. Remedy: a. Verify encoder adjustment (machine reference ) or readjust encoder. b. Replace the encoder, replace or screen the enc oder cable (or deactivate zero mark monitoring). Program Continuation: Clear alarm with the Delete key or NC START. Diagnostics Manual (DAsl), 03/2009
