What it means
F32820 reports a telegram error in the DRIVE-CLiQ communication between the Control Unit and Encoder 2 — the drive object is the Sensor Module Encoder 2. The drive raises the condition as a fault; depending on how the drive is configured, the same condition can also be issued with no reaction (N) or as an alarm (A).
Why it appears
- A DRIVE-CLiQ communication error has occurred from the Control Unit to the encoder concerned (Sensor Module Encoder 2). The manuals for all four families describe this cause identically, so it is given here once.
What to check
carry out a POWER ON (switch-off/switch-on)
— power the drive down and back up.- Check the electrical cabinet design and cable routing for EMC compliance.
- Check the DRIVE-CLiQ wiring (interrupted cable, contacts, ...).
Reading the message value
- The drive puts the component number and the fault cause into the message value. It is coded in r0949/r2124 as 0000yyxx hex: yy = component number, xx = error 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 component in the telegram and in the receive list do not match.
- 7 (= 07 hex): A SYNC telegram is expected - but the received telegram is not a SYNC telegram.
- 8 (= 08 hex): No SYNC telegram is expected - but the received telegram is one.
- 9 (= 09 hex): The error bit in the receive telegram is set.
- 16 (= 10 hex): The receive telegram is too early.
Parameters the manual names
- r0949 (fault value) — read the coded message value of this fault here: 0000yyxx hex with the component number and the fault cause.
- r2124 (alarm value) — carries the same coding when the condition is signalled as an alarm instead of a fault.
- p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave) — the manual for the G130 and G150 cross-refers to this parameter in the remedy for this fault.
Acknowledging and restarting
Once the cause has been removed, carry out a POWER ON (switch-off/switch-on)
and acknowledge the fault; the drive can then be restarted. No further reset action is described for this code. When the condition is configured as an alarm or without reaction, no fault acknowledgement is involved.
What differs between the drive families
Straight from the manuals' own fields — F32820 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Servo: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) Vector: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) Hla: OFF1 (NONE, OFF2, OFF3) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Sensor Module Encoder 2 | SINAMICS S120, S150 List Manual · p. 3118 |
| G130, G150 | OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Sensor Module Encoder 2 | SINAMICS G130, G150 List Manual · p. 1795 |

Questions technicians ask
What does fault F32820 mean on a SINAMICS drive?
It reports a DRIVE-CLiQ telegram error between the Control Unit and Encoder 2 (the Sensor Module Encoder 2). Depending on the configuration, the same condition can also be issued as an alarm or without any reaction.
How do I fix fault F32820?
Carry out a POWER ON (switch-off/switch-on), then check the electrical cabinet design and cable routing for EMC compliance and inspect the DRIVE-CLiQ wiring for interrupted cables or poor contacts. Afterwards acknowledge the fault.
How do I find the exact cause of F32820?
Read the message value in r0949, or in r2124 if the condition came as an alarm. It is coded 0000yyxx hex: yy is the component number and xx the fault cause — for example, 01 hex means a checksum error (CRC error).
Can F32820 appear as an alarm instead of a fault?
Yes. Depending on the drive's configuration, the same condition can be issued with no reaction (N) or as an alarm (A) instead of a fault.
