What it means
A50007 is COMM BOARD: Alarm 7
. The drive raises it when the CBE20 communications board is used for SINAMICS Link and one of the configured send telegram words (PZD send words) is greater than possible in the project. The alarm value in r2124 identifies the drive object number and the index from p8871 concerned. Depending on the drive configuration, the same condition can also be output as fault F50007.
Why it appears
- CBE20 SINAMICS Link: a send telegram word is configured that is greater than what is possible in the project.
What to check
- Read the alarm value in r2124 in hexadecimal (format yyyyxxxx hex): the upper half yyyy gives Info 1, the lower half xxxx gives Info 2. Read in decimal, Info 1 is the drive object number and Info 2 is the index from p8871 — this tells you which send word is affected.
- Correct the parameter assignment of the SINAMICS Link PZD send words (p8871) so that no send telegram word exceeds what is possible in the project; the project the send words must fit is selected in p8811 (SINAMICS Link project selection).
Reading the message value
- The drive stores the value in r2124 (alarm value); it must be interpreted in hexadecimal and has the format yyyyxxxx hex.
- yyyy (upper half) = Info 1, xxxx (lower half) = Info 2 — these are the two values the drive places in the message value (
Info. 1: %1, info. 2: %2
). - Info 1, read in decimal, is the drive object number from p8871.
- Info 2, read in decimal, is the index from p8871.
Parameters the manual names
- r2124 — alarm value: read it here in hexadecimal to obtain the two info values of this alarm.
- p8871 — SINAMICS Link PZD send word: the send word assignment whose drive object number (Info 1) and index (Info 2) the alarm value points to, and which has to be corrected.
- p8811 — SINAMICS Link project selection: selects the project that the send telegram words must fit.
Acknowledging and restarting
As an alarm, A50007 requires no acknowledgement. If the drive is configured to output the same condition as fault F50007 instead, that fault must be acknowledged immediately; no automatic OFF1, OFF2 or OFF3 reaction is triggered in that case.
The same on every family
Every manual that describes A50007 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Communication error to the higher-level control system (9) | None | SINAMICS S120, S150 List Manual · p. 3301 |
| G130, G150 | NONE | NONE | Communication error to the higher-level control system (9) | None | SINAMICS G130, G150 List Manual · p. 1938 |

Questions technicians ask
What does alarm A50007 mean on a SINAMICS drive?
It is COMM BOARD: Alarm 7: on the CBE20 communications board used for SINAMICS Link, a configured send telegram word is greater than possible in the project.
How can I see which SINAMICS Link send word caused A50007?
Read the alarm value in r2124 in hexadecimal (yyyyxxxx hex): read in decimal, the upper half yyyy gives the drive object number and the lower half xxxx the index from p8871.
How do I fix A50007?
Correct the parameter assignment of the SINAMICS Link PZD send words in p8871 so that no send telegram word exceeds what the project allows. As an alarm the message needs no acknowledgement; as fault F50007 it must be acknowledged immediately.
Which parameters belong to A50007?
p8871 holds the SINAMICS Link PZD send words, p8811 selects the SINAMICS Link project, and r2124 contains the alarm value with the two info values.
