ECODRIVE03 SMT-02VRS Description of Diagnostic Letters B..., C..., D... and A... 4-31
DOK-ECODR3-SMT-02VRS**-WA01-EN-P
4.2 Status diagnostic messages
A000 Communication phase 0
The communication process is divided into four communication phases:
Phases 0 and 1 are used to recognize the participants. Phase 2 is used to
prepare the time and data protocols for communication phases 3 and 4.
Initialization is performed in ascending order of the sequence. The
defaults of the communication phase are set by the control system. When
the switch to communication phase 4 takes place, initialization is
completed and input power is enabled.
If the phase switch is interrupted, the status display remains in the
communications phase which has already been reached.
If diagnostic message A000 Communication phase 0 is active, the drive
is in phase 0 and is waiting for a phase transfer to 1 by the control
system.
See also the functional description: "Parametrization Mode - Operating
Mode".
A001 Communication phase 1
The communication process is divided into four communication phases:
Phases 0 and 1 are used to recognize the participants. Phase 2 is used to
prepare the time and data protocols for communication phases 3 and 4.
Initialization is performed in ascending order of the sequence. The
defaults of the communications phase are set by the control system.
When the switch to communications phase 4 takes place, initialization is
completed and input power is enabled.
If the delayed phase switch is interrupted, the status display remains in
the communications phase which has already been reached.
If diagnostic message A001 Communication phase 1 is active, the drive
is in phase 1, and transfer from phase 1 to 2 has not yet been initiated by
the control system.
See also the functional description: "Parametrization Mode - Operating
Mode".
A002 Communication phase 2
For field bus and SERCOS devices, the control demands via the master
communication "communication phase 2", or the drive has been switched
to phase 2 by the command P-0-4023, C400 Communication phase 2
transition. Therefore, the drive is in the "parameter mode". In this mode,
many parameters are editable, which can no more be edited in
"communication phase 4" ("operation mode").
In this phase, usually
• for field bus and SERCOS devices, the communication parameters
are transferred from the control to the drive and
• the functions Load and Save parameters ("file services“) are
performed when needed.
