Error Codes

Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error A1009: Control module over-temperature

  The temperature of the control module (Control Unit) has exceeded the specified limit value. The manual's first action is: “Check the air intake for the Control Unit. Check the Control Unit fan.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F52987: Absolute encoder replaced

  Incorrect absolute encoder data. The manual's first action is: “Contact the Hotline.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F52985: Absolute encoder motor wrong

  Motor ID is downloaded wrong during manufacture. The firmware of the servo drive does not support the Motor ID. The manual's first action is: “Update the firmware.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F52984: Incremental encoder motor not configured

  Commissioning of the servo motor has failed. The incremental encoder motor is connected but fails to commission. The manual's first action is: “Configure the motor ID by setting the parameter p29000.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F52983: No encoder detected

  The servo drive in use does not support encoderless operation. The manual's first action is: “Check the encoder cable connection between the servo drive and the servo motor.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F52881: Absolute encoder motor mismatched

  Connected absolute encoder motor cannot be operated. The servo drive in use does not support the Motor ID. The manual's first action is: “Use a suitable absolute encoder motor.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F52980: Absolute encoder motor changed

  The servo motor with absolute encoder is changed. Actual motor ID is different from commissioned motor ID. The manual's first action is: “The servo motor will be automatically configured after the acknowledgement of t…

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F52904: Control mode change

  When the control mode is changed, the drive must be saved and restarted. The manual's first action is: “Save and restart the drive.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F31150: Initialization error

  Encoder functionality is not operating correctly. The manual's first action is: “Check the encoder type used (incremental/absolute) and the encoder cable.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F31131: Encoder 1: Deviation position incremental/absolute too large

  Absolute encoder When cyclically reading the absolute position, an excessively high difference to the incremental position was detected. Incremental encoder When the zero is passed, a deviation in the incremental posi…

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F31130: Zero mark and position error from the coarse synchronization

  After initializing the pole position using track C/D, Hall signals or pole position identification routine, the zero mark was detected outside the permissible range. The manual's first action is: “Check that the encod…

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F31117: Inversion error signals A/B/R

  For a square-wave encoder (bipolar, double ended) signals A*, B* and R* are not inverted with respect to signals A, B and R. The manual's first action is: “Check the encoder and cable and the connection of them.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F31112: Error bit set in the serial protocol

  The encoder sends a set error bit via the serial protocol. The manual's first action is: “Refer to F3111.”

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F31111: Encoder 1: Absolute encoder internal error

  An internal fault has been detected in the absolute encoder, indicated by set fault bits from its fault word. The manual's first action is: “Check the encoder cable connection and make sure the cables are routed in co…

• CodeSiemens SINAMICS V90, SIMOTICS S-1FL6 Error F31110: Serial communications error

  A serial communication error occurred between the encoder and evaluation module during protocol transfer. The manual's first action is: “Check the encoder cable and shielding connection.”
