Siemens A07441 fault code meaning
Siemens / A07441
Series: G120-CU250S-2
Position loop: Back up the position offset for absolute encoder adjustment
converter
Meaning: The absolute encoder adjustment status has changed. To retain the detected position offset (p2525) permanently, it must be saved to nonvolatile storage (p0971).
Possible causes
Source: SINAMICS G120, Control Unit CU250S-2 P1380
Series: G120D
Position loop: Back up the position offset for absolute encoder adjustment
converter
Meaning: The absolute encoder adjustment status has changed. To permanently accept the detected position offset (p2525), it must be saved in nonvolatile storage (p0971).
Possible causes

Series: G130-G150, S120-S150
Position loop: Back up the position offset for absolute encoder adjustment
converter
Meaning: The absolute encoder adjustment status has changed. Nonvolatile storage (p0971, p0977) is required to permanently retain the detected position offset (p2525) and drive data set number (p2733). Possible causes: - The motor or encoder has been replaced (applies to EQN and DQI). - Position-related parameters have changed. - An uncalibrated encoder has been calibrated (using the "Copy from RAM to ROM" nonvolatile storage item).

Position loop: Back up the position offset for absolute encoder calibration
converter
Meaning: The absolute encoder calibration status has changed. To permanently apply the detected position offset and drive data set number, save the parameters in nonvolatile memory (p0977). Possible causes: - The motor or encoder has been replaced (applies to EQN and DQI). - Parameters related to the forward direction have changed. - An uncalibrated encoder has been calibrated (project saved in nonvolatile memory). Note: Provided that the configurable monitoring window has not been exited, previous axis motion will not trigger this message after power-on.

Meaning: The absolute encoder calibration status has changed. To permanently apply the detected position offset (p2525) and drive data set number (p2733), save the parameters in nonvolatile memory (p0977). Possible causes: - The motor or encoder has been replaced (applies to EQN and DQI). - Parameters related to the forward direction have changed. - An uncalibrated encoder has been calibrated (project saved in nonvolatile memory). Note: As long as the axis has not left the configurable monitoring window, previous axis movements will not cause this message after power-on again.
