13.3 DRIVE-CLiQ component firmware update
Update process
The update process can take a few minutes. It is indicated by the RDY LED on the relevant
component flashing green/red and the RDY LED for SINAMICS Integrated (or on the control
unit) flashing yellow at 0.5 Hz.
A progress indicator is implemented in parameter p7827.
The update is complete when the RDY LED of the SINAMICS Integrated (control unit) stops
flashing at 0.5 Hz. Once the upgrade has ended, the RDY LED for the component in
question remains continuously lit, provided the upgrade is complete and the new firmware
has been activated.
For components whose RDY LED is flashing green/red at 2 Hz, you need to perform a
POWER OFF/POWER ON to activate the new firmware.
For components without LED (for example motors with DRIVE-CLiQ interface), check for
relevant warnings on the drive.
Note
During activation of the new firmware, it is possible for a component to interrupt cyclic
communication. In this case, communication faults occur and must be acknowledged.
You can check the firmware versions of the individual components with parameters. The
versions of the DRIVE-CLiQ components and those of SINAMICS Integrated (or of the
control unit) may differ.
Note
DRIVE-CLiQ components with higher firmware versions are backward compatible and can
also operate with DRIVE-CLiQ components with lower firmware versions.
Automatic firmware update
You can use parameter p7826 to influence the response for automatic firmware updates of
DRIVE-CLiQ components.
With the automatic firmware update, the firmware version of the DRIVE-CLiQ components is
checked against the firmware version of SINAMICS Integrated (or the control unit) and if
necessary updated upon each power up. This means power up can take a few minutes
longer.
The following settings are possible:
● p7826 = 0: Upgrade and downgrade deactivated
● p7826 = 1: Upgrade and downgrade (factory setting)
● p7826 = 2: upgrade only
A parameter change does not become effective until the next drive system power up.
Where Safety Basic, Extended and/or Advanced Functions are enabled, the system checks
whether the parameter for automatic firmware updates p7826 = 1 is set. Otherwise, the
following message is output: F01664 (SI CU: No automatic firmware update).
