Communication Phase 3
Transition Check
DOK-INDRV*-MP*-02VRS**-FK01-EN-P
The procedure comprises several steps and is controlled by the master by
presetting communication phases –1 to 4 and starting/completing the
following commands:
• S-0-0127, C0100 Communication phase 3 transition check
• S-0-0128, C0200 Communication phase 4 transition check
.
When the drive has reached communication phase 4 without error, the
display reads "bb".
The corresponding diagnostic message is:
• A0013 Ready for power on
Transition Check Commands
To switch from communication phase 2 to 3 and from 3 to 4 it is
necessary to activate transition check commands in the drive:
S-0-0127, C0100 Communication phase 3 transition check
S-0-0128, C0200 Communication phase 4 transition check
Note:
In order to get back from the operating mode to the
parameterization mode, there is the command P-0-4023,
C0400 Communication phase 2 transition.
By executing the command S-0-0127, C0100 Communication phase 3
transition check a number of checks and parameter conversions are
carried out that can possibly cause the listed command errors:
• General checks
• C0131 Switching to phase 3 impossible
• C0199 Functional package selection changed. Restart
• Checking the validity of the parameters required for switching to
phase 3
If one of these parameters has never been written or the backup was
carried out incorrectly, the error message "C0101" is generated. The
IDNs of the faulty parameters are listed in parameter S-0-0021, IDN
list of invalid operating data for communication phase 2. These
parameters have to be set valid by writing correct values to them.
• C0101 Invalid parameters (->S-0-0021)
• C0102 Limit error in parameter (-> S-0-0021)
• C0103 Parameter conversion error (->S-0-0021)
• C0138 Invalid control section data (->S-0-0021)
• Checking the telegram configuration, especially in the case of
configured telegrams
In this case a check is run to find out whether the parameters selected
for the configurable data block in the cyclic command value channel
(MDT) or actual value channel (AT) may be configured and whether
the allowed length of the configurable data blocks is complied with.
Diagnostic messages for SERCOS interface:
• C0104 Config. IDN for MDT not configurable
• C0105 Maximum length for MDT exceeded
• C0106 Config. IDNs for AT not configurable
• C0107 Maximum length for AT exceeded
Diagnostic messages for field bus interface:
• C0154 Field bus: IDN for cycl. command val. not configurable
