Siemens A31920 fault code meaning

Siemens / A31920

Series: G120-CU250S-2

Encoder 1: Temperature sensor fault

converter

Meaning: %1, Channel number: %2. Drive object: CU250S_S, CU250S_S_CAN, CU250S_S_DP, CU250S_S_PN. Reaction: None. Acknowledgment: None. Cause: A fault occurred during temperature sensor measurement. Fault cause: 1 (= 01 hexadecimal): Open circuit or sensor not connected (KTY:R > 1630 ohms). 2 (= 02 hexadecimal): The measured resistance is too small (PTC: R < 20 ohms, KTY: R < 50 ohms). Other values: For Siemens internal fault diagnostics only. Note on the message value: Detailed information is encoded in the message value (r0949/r2124) as follows: 0000yyxx hex: yy = channel number, xx = fault cause. See: p0491 (Motor encoder fault reaction "Encoder").
