Drive-Cliq Diagnostics; Emergency Operating Mode For Drive-Cliq Components - Siemens SINAMICS S120 Function Manual

DRIVE-CLiQ diagnostics

Using the DRIVE-CLiQ diagnostics, you can check the connections and cables of DRIVE-
CLiQ connections. For data transfer errors, to localize the faulted connection, the error
counter in the involved blocks can be evaluated.
In addition to the error counter showing all errors, detailed diagnostics can be carried out for
the individual connections. For selected connections, the number of errors is determined for
a time interval that can be specified and made traceable using a parameter. As a result of
the interconnectability, you can record when data transfer errors occur and correlate them
with other events in the drive.

Emergency operating mode for DRIVE-CLiQ components

In order to protect the drive system against excessive voltage when the Control Unit or
DRIVE-CLiQ communication fails (e.g. while a spindle is rotating), an autonomous
emergency operating mode (independent operation) is integrated in DRIVE-CLiQ
components for the following functions:
● Chopper mode (for Basic Line Module 20 kW / 40 kW in combination with an external
braking resistor).
● Integrated voltage protection for machines with a high kinetic energy (armature short-
circuit controlled by the Motor Modules on the basis of the DC link voltage).
Features
● Resumption and resynchronization of DRIVE-CLiQ communication in emergency mode
when necessary (only if clock cycle conditions have not changed) and without POWER
ON.
● Changeover from emergency operation to normal operation without POWER ON of the
component.
● Defined response with factory setting / project download.
