F32860 — Encoder 2 DRIVE-CLiQ (CU): Telegram error

F32860 signals a DRIVE-CLiQ telegram error on the path from the Sensor Module used as encoder 2 to the Control Unit: a telegram was received with a checksum error, with a length, type or address that does not match the receive list, it arrived too early, or the component itself reported that its supply voltage has failed. The drive stores the component number and the fault cause together in one message value, which you decode as described under “Fault value” below. Depending on how the drive is configured, the same condition can also be output as an alarm or with no reaction at all.

• A DRIVE-CLiQ communication error has occurred on the path from the Sensor Module involved (encoder 2) to the Control Unit. The manuals for all four families describe this cause identically; which specific error occurred is coded in the message value (see the fault cause list below).

1. Carry out a POWER ON (switch-off/switch-on).
2. Check the electrical cabinet design and the cable routing for EMC compliance.
3. Check the DRIVE-CLiQ wiring (interrupted cable, contacts, …).
4. The description of this fault for the G130/G150 additionally refers to p9915 (DRIVE-CLiQ data transfer error shutdown threshold master).

• Format: the manual prints the message value as “Component number: %1, fault cause: %2” and codes both into one value, readable in r0949 (fault) or r2124 (alarm): 0000yyxx hex, where yy is the component number and xx the fault cause.
• 1 (01 hex): Checksum error (CRC error).
• 2 (02 hex): Telegram is shorter than specified in the length byte or in the receive list.
• 3 (03 hex): Telegram is longer than specified in the length byte or in the receive list.
• 4 (04 hex): The length of the receive telegram does not match the receive list.
• 5 (05 hex): The type of the receive telegram does not match the receive list.
• 6 (06 hex): The address of the power unit in the telegram and in the receive list do not match.
• 9 (09 hex): The DRIVE-CLiQ communication from the DRIVE-CLiQ component involved to the Control Unit signals that the supply voltage has failed.
• 16 (10 hex): The receive telegram is too early.
• 17 (11 hex): CRC error and the receive telegram is too early.
• 18 (12 hex): The telegram is shorter than that specified in the length byte or in the receive list and the receive telegram is too early.
• 19 (13 hex): The telegram is longer than that specified in the length byte or in the receive list and the receive telegram is too early.
• 20 (14 hex): The length of the receive telegram does not match the receive list and the receive telegram is too early.
• 21 (15 hex): The type of the receive telegram does not match the receive list and the receive telegram is too early.
• 22 (16 hex): The address of the power unit in the telegram and in the receive list does not match and the receive telegram is too early.
• 25 (19 hex): The error bit in the receive telegram is set and the receive telegram is too early.

• r0949 (fault value): read the message value of this fault here — coded 0000yyxx hex, it gives the component number (yy) and the fault cause (xx) for this event.
• r2124 (alarm value): when the condition is raised as an alarm, the same coded value is read here instead.
• p9915 (DRIVE-CLiQ data transfer error shutdown threshold master): named in the remedy of the G130/G150 description of this fault.

Carry out a POWER ON (switch-off/switch-on) as the remedy prescribes, then acknowledge the fault immediately; afterwards the drive can be restarted. If the drive is configured to output this condition only as an alarm or with no reaction at all, the manual specifies neither a reaction nor an acknowledgement.
