What it means
F01057 is an internal error of the Control Unit (CU): the same slave component has been requested with different DRIVE-CLiQ types — the manual names hps_ps and hps_enc as examples of these types. The message is documented for the G130, G150, S120 and S150 and is always raised by the Control Unit. The manual adds that the fault is only for internal Siemens troubleshooting, so no deeper analysis is documented for the user; the fault value in r0949 identifies the internal method involved.
Why it appears
- The same slave component has been requested with different DRIVE-CLiQ types (hps_ps, hps_enc, ...).
- No further causes are documented — the manual marks the fault as only for internal Siemens troubleshooting.
What to check
- Read the fault value from r0949; the manual specifies that it is interpreted hexadecimal and contains the Method ID.
- Contact Technical Support and quote the fault F01057 together with the fault value — the manual gives this as the only remedy and describes no check or repair the user can perform.
Reading the message value
- The drive stores the fault value in r0949; it must be interpreted hexadecimal.
- Content of the fault value: the Method ID.
Parameters the manual names
- r0949 — fault value of this fault: read it (interpret hexadecimal) to obtain the Method ID before contacting Technical Support.
Acknowledging and restarting
Acknowledge the fault immediately once it is displayed. The drive itself takes no protective action for this fault, and the manual describes no user-side repair — contacting Technical Support is the only remedy given, so clearing the message does not remove the underlying internal error.
The same on every family
