What it means
F35052 is raised when an internal software or hardware error has been detected on the Terminal Module 54F (TM54F). The S120/S150 and G130/G150 list manuals describe this message identically for the terminal module, so the same explanation applies on every family listed. Depending on how the drive is configured, the same condition can also be signaled as an alarm.
Why it appears
- An internal software or hardware error has been detected on the Terminal Module 54F (TM54F).
What to check
- Check the electrical cabinet design and the cable routing for EMC compliance.
- Upgrade the TM54F firmware to a more recent version.
- Contact Technical Support.
- Replace the TM54F.
Reading the message value
- The drive stores the fault value in r0949, to be interpreted as a decimal number.
- The manual decodes nothing: the value is
Only for internal Siemens troubleshooting
.
Parameters the manual names
- r0949 — read out the fault value here in decimal notation; per the manual it serves only internal Siemens troubleshooting.
Acknowledging and restarting
Acknowledge the fault immediately; this acknowledgment requires a POWER ON, so the drive must be switched off and back on before the message is cleared. When the condition is signaled as an alarm instead, no acknowledgment is required.
