What it means
A01839 is an alarm from the DRIVE-CLiQ diagnostics of the Control Unit. It appears when the fault counter r9936, which monitors the DRIVE-CLiQ connections and cables, has been incremented. The alarm value r2124, to be interpreted as a decimal number, carries the component number, so the alarm itself names the component whose feeder cable from the direction of the Control Unit is faulted. The alarm needs no acknowledgement and withdraws itself again; the drive does not trip.
Why it appears
- The fault counter r9936, which monitors the DRIVE-CLiQ connections/cables, has been incremented.
- The component number in the alarm value specifies the component whose feeder cable from the direction of the Control Unit is faulted.
What to check
- Note the component number: the alarm value r2124, interpreted as a decimal number, specifies the component whose feeder cable from the direction of the Control Unit is faulted.
- Check the corresponding DRIVE-CLiQ cables.
- Check the electrical cabinet design and cable routing for EMC compliance.
Reading the message value
- Message value: Component number: %1 — the drive enters the number of the affected component.
- Alarm value (r2124, interpret decimal): Component number.
- The component number specifies the component whose feeder cable from the direction of the Control Unit is faulted.
Parameters the manual names
- r2124 — alarm value: read it as a decimal number for this alarm; it contains the component number of the faulted feeder cable.
- r9936 — DRIVE-CLiQ diagnostic error counter connection: the counter that monitors the DRIVE-CLiQ connections/cables and whose incrementing this alarm reports.
Acknowledging and restarting
No acknowledgement is required. The alarm is automatically withdrawn after 5 seconds, assuming that no other data transfer error has occurred.

Questions technicians ask
What does A01839 mean on a SINAMICS drive?
It is an alarm from the DRIVE-CLiQ diagnostics: the fault counter r9936 monitoring the DRIVE-CLiQ connections/cables has been incremented, which points to a fault on the DRIVE-CLiQ feeder cable of one component.
Which cable is affected when A01839 appears?
The alarm value r2124, read as a decimal number, contains the component number; it specifies the component whose feeder cable from the direction of the Control Unit is faulted.
Does A01839 have to be acknowledged?
No. The alarm is automatically withdrawn after 5 seconds, assuming that no other data transfer error has occurred.
What should I check for A01839?
Check the corresponding DRIVE-CLiQ cables, and check the electrical cabinet design and cable routing for EMC compliance.
