F01380 — Topology: Actual topology EEPROM defective

F01380 is raised when the drive, while detecting the actual topology, identifies a component with a defective EEPROM. The G130/G150 and S120/S150 list manuals describe this fault identically, so the cause and remedy below apply unchanged. The drive stores a fault value in r0949 that names the defective component by its preliminary component number, and the operator panel or commissioning tool shows the message value Preliminary component number: %1. The fault triggers no automatic drive response — the remedy is to read out the fault value and remove the component it points to.

• While detecting the actual topology, the drive detected a component with a defective EEPROM.

1. Output the fault value: read r0949 and interpret the value in hexadecimal — it has the structure bbbbaaaa hex, where aaaa is the preliminary component number of the defective components and bbbb is reserved.
2. Remove the defective component identified by this preliminary component number.

The drive stores the fault value in r0949 and it must be interpreted in hexadecimal. The message value Preliminary component number: %1 shows that the drive fills the placeholder %1 with the preliminary component number of the defective component. The fault value decodes as follows:

• bbbbaaaa hex — bbbb = reserved
• aaaa = preliminary component number of the defective components

• r0949 — fault value: for this code, read it out and interpret it in hexadecimal; the aaaa portion of the bbbbaaaa hex value gives the preliminary component number of the defective component.

This fault is acknowledged with POWER ON — the drive has to be switched off and on again; an acknowledge command alone does not clear it. Because the drive does not trip automatically when the fault appears, the practical sequence is: read the preliminary component number from r0949, remove the defective component, and then power the drive down and up again to acknowledge the fault.
