What it means
F08000 means that Terminal Board 30 has detected an incorrect internal power supply voltage — the +/-15 V supply named in the message text. The monitoring is performed in the Controller Extension (CX). Depending on how the drive is configured, the same condition can also be issued as an alarm (A) or with no reaction at all (N).
The fault value stored in r0949 tells you in which situation the incorrect voltage was detected; the interpretation is listed below.
Why it appears
- Terminal Board 30 detects an incorrect internal power supply voltage.
- The stored fault value distinguishes the two cases the manual names: an error during the test of the monitoring circuit, or a fault that occurred in normal operation.
What to check
- Replace Terminal Board 30.
- If replacing Terminal Board 30 does not clear the condition, replace the Control Unit.
Reading the message value
- The fault value is stored in r0949 and must be interpreted as a decimal number.
- 0 — an error occurred when the monitoring circuit was being tested.
- 1 — the fault occurred in normal operation.
Parameters the manual names
- r0949 — read the fault value here, interpreted as a decimal number, to see whether the +/-15 V error was detected during the test of the monitoring circuit (0) or in normal operation (1).
Acknowledging and restarting
When the condition appears as a fault, it is acknowledged immediately by means of POWER ON — the drive's power supply must be switched off and on again before it will restart; the manual describes no other reset action. Where the drive outputs the same condition as an alarm (A) or with no reaction (N), neither a reaction nor an acknowledgment is specified.
What differs between the drive families
Straight from the manuals' own fields — F08000 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Infeed: NONE (OFF1, OFF2) Servo: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2) Vector: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2) Hla: NONE (OFF1, OFF2, OFF3, STOP2) | IMMEDIATELY (POWER ON) | Supply voltage fault (undervoltage) (3) | Controller Extension (CX) | SINAMICS S120, S150 List Manual · p. 2917 |
| G130, G150 | Vector: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2) Infeed: NONE (OFF1, OFF2) | IMMEDIATELY (POWER ON) | Supply voltage fault (undervoltage) (3) | Controller Extension (CX) | SINAMICS G130, G150 List Manual · p. 1632 |

Questions technicians ask
What does SINAMICS fault F08000 mean?
Terminal Board 30 has detected an incorrect internal power supply voltage, namely a fault in the +/-15 V supply monitored in the Controller Extension (CX).
How do I clear fault F08000?
Acknowledge it immediately by switching the drive's power supply off and on again (POWER ON). The manual names no further reset procedure.
What needs to be replaced for F08000?
The manual's remedy is to replace Terminal Board 30 and, if that does not eliminate the fault, to replace the Control Unit. No checks are described beyond these two steps.
What does the fault value of F08000 tell me?
Read r0949 as a decimal number: 0 means an error occurred while the monitoring circuit was being tested, and 1 means the fault occurred in normal operation.
