What it means
A36802 (Hub: Time slice overflow) is raised when a time slice overflow has occurred on the DRIVE-CLiQ Hub Module. The alarm value identifies the time slice concerned. Depending on the drive's configuration, the same condition can also be issued as a fault (F) or with no reaction (N).
Why it appears
- A time slice overflow has occurred on the DRIVE-CLiQ Hub Module. The manuals name this as the only cause; no further conditions are listed for this message.
What to check
- Reduce the current controller frequency.
- Carry out a POWER ON (switch-off/switch-on) for all components.
- Upgrade the firmware to a later version.
- If the alarm reappears afterwards, contact Technical Support.
Reading the message value
- The drive writes the message value to r0949; interpret it as a decimal number.
- Decoding as the manual prints it:
xx: Time slice number xx
— the value is the number of the time slice in which the overflow occurred.
Parameters the manual names
- r0949 — read the message value of A36802 here; interpreted as a decimal number it gives the number of the overflowing time slice.
Acknowledging and restarting
As an alarm, A36802 requires no acknowledgment: the drive takes no action of its own, and the message clears once the hub module no longer reports the overflow. The remedy nonetheless includes a POWER ON (switch-off/switch-on) for all components. Where the configuration raises the same condition as a fault instead, it is acknowledged immediately after that POWER ON.
The same on every family
Every manual that describes A36802 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does SINAMICS alarm A36802 mean?
It reports that a time slice overflow has occurred on the DRIVE-CLiQ Hub Module. The value in r0949, read as a decimal number, names the affected time slice.
How do I clear A36802?
Reduce the current controller frequency and then carry out a POWER ON (switch-off/switch-on) for all components. If the alarm returns, upgrade the firmware and contact Technical Support.
Where can I see which time slice overflowed?
In r0949. Interpret the value as a decimal number — it is the number of the time slice in which the overflow occurred.
Does A36802 need to be acknowledged?
As an alarm it needs no acknowledgment and goes away once the overflow is no longer reported. If the drive issues the condition as a fault, it is acknowledged immediately after the POWER ON (switch-off/switch-on).
