Message value: Fault cause: %1 bin Drive object: All objects Reaction: A_INFEED: NONE SERVO: ENCODER (IASC/DCBRAKE, NONE) VECTOR: ENCODER (IASC/DCBRAKE, NONE) Acknowledge: PULSE INHIBIT SINAMICS-Alarms Cause: Serial communication protocol transfer er ror between the encoder and evaluation module. Fault value (r0949, interpret binary): Bit 0: Alarm bit in the position protocol. Bit 1: Incorrect quiescent level on the data line. Bit 2: Encoder does not respond (does not supply a start bit within 50 ms). Bit 3: CRC error: The checksum in the protoc ol from the encoder does not match the data. Bit 4: Encoder acknowledgement error: The encoder incorrectly understood the task (request) or cannot execute it. Bit 5: Internal error in the serial driv er: An illegal mode command was requested. Bit 6: Timeout when cyclically reading. Bit 8: Protocol is too long (e.g. > 64 bits). Bit 9: Receive buffer overflow. Bit 10: Frame error when reading twice. Bit 11: Parity error. Bit 12: Data line signal level error during the monoflop time. Bit 13: Data line incorrect. Remedy: Re fault value, bit 0 = 1: - encoder defective. F31111 may provide additional details. Re fault value, bit 1 = 1: - Incorrect encoder type / repl ace the encoder or encoder cable. Re fault value, bit 2 = 1: - Incorrect encoder type / repl ace the encoder or encoder cable. Re fault value, bit 3 = 1: - EMC / connect the cable shield, r eplace the encoder or encoder cable. Re fault value, bit 4 = 1: - EMC / connect the cable shield, replace the encoder or encoder cable, replace the Sensor Module. Re fault value, bit 5 = 1: - EMC / connect the cable shield, replace the encoder or encoder cable, replace the Sensor Module. Re fault value, bit 6 = 1: - Update the firmware for the Sensor Module. Re fault value, bit 8 = 1: - Check the parameterization (p0429.2). Re fault value, bit 9 = 1: - EMC / connect the cable shield, replace the encoder or encoder cable, replace the Sensor Module. Re fault value, bit 10 = 1: - Check the parameterization (p0429.2, p0449). Re fault value, bit 11 = 1: - Check the parameterization (p0436). Re fault value, bit 12 = 1: - Check the parameterization (p0429.6). Re fault value, bit 13 = 1: - Check the data line.
