NOTICE
SIMATIC Drive Controllers with a hardware function version ≥ FS 09 have a CPU firmware
version ≥ V2.9. You must not downgrade these SIMATIC Drive Controllers to CPU firmware
version V2.8.
The CPU firmware version V2.8 may no longer be executable on SIMATIC Drive Controllers
with hardware function version ≥ FS 09. In this case, the downgrading can no longer be
reversed and the device must be sent in.
SINAMICS Integrated firmware missing or incompatible
If there is no SINAMICS Integrated firmware or the firmware is incompatible with the CPU,
this is signaled by a red flashing RDY LED (2 Hz) and a red ERROR LED. A corresponding error
message is also entered in the diagnostic buffer.
If the SIMATIC Memory Card has a SINAMICS Integrated firmware version that is incompatible
with the CPU firmware, the SINAMICS Integrated firmware update is rejected. The ERROR LED
flashes red and the MAINT LED flashes yellow. A corresponding error message is also entered
in the diagnostic buffer.
An update of the CPU firmware, however, is always possible.
Update sequence
If the SINAMICS Integrated firmware also needs a new CPU firmware, then the CPU firmware
must always be updated first and then activated by a CPU restart. (CPU restart through power
off/on or by removing/inserting the SIMATIC Memory Card).
Examples:
• The service pack of SINAMICS firmware V5.2 SP3 (V5.2.3) requires at least CPU firmware
V2.9
• SINAMICS Integrated update files (upd files) with a 3-digit version need at least CPU
firmware V3.0
Update with SIMATIC Memory Card
If both update files for CPU and SINAMICS Integrated firmware are located on the SIMATIC
Memory Card in the directory FWUPDATE.S7S, a distinction must be made between the
following two cases:
Case 1: The SINAMICS Integrated firmware does not need any new CPU firmware
The CPU and SINAMICS Integrated firmware is updated in one process.
Case 2: The SINAMICS Integrated firmware also needs a new CPU firmware
In this case, a two-step procedure is required. When you carry out the firmware update, only
the CPU firmware is updated first. The SINAMICS Integrated update is rejected with errors
(ERROR LED flashes red).
In order for the SINAMICS Integrated firmware to also be updated successfully in a second
step, you have to force a CPU restart through power off/on or by removing/inserting the
SIMATIC Memory Card.
The CPU firmware is activated due to the restart and another update for the SINAMICS
