Remedy: - use the current version of the commissioning software.
- modify the offline project and carry out a new download (e.g. compare the number of drive objects, motor, encoder,
power unit in the offline project and at the drive).
- change the drive system (is a drive rotating or is there a message/signal?).
- carefully note any other messages/signals and remove their cause.
F01044 CU CompactFlash: Message incorrectly written
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: An error was detected when loading the message descriptions (FDxxxyyy.ACX) saved on the CompactFlash card.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: Replace the CompactFlash card.
A01045 CU CompactFlash: Configuring data invalid
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An invalid data type was detected when evaluating parameter files PSxxxyyy.ACX, PTxxxyyy.ACX, CAxxxyyy.ACX
or CCxxxyyy.ACX, saved on the CompactFlash card.
Alarm value (r2124, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: Restore the factory setting using (p0976 = 1) and re-load the project into the drive unit. Operation without any restric-
tions is then possible.
After downloading the project, save the parameterization in STARTER using the function "Copy RAM to ROM" or
with p0977 = 1. This means that the incorrect parameter files are overwritten on the CompactFlash card.
A01046 (F) CU CompactFlash: Configuring data invalid
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An invalid data type was detected when evaluating the parameter files PSxxxyyy.ACX, PTxxxyyy.ACX, CAxxx-
yyy.ACX or CCxxxyyy.ACX saved on the CompactFlash card.
Alarm value (r2124, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: Restore the factory setting using (p0976 = 1) and re-load the project into the drive unit. Operation without any restric-
tions is then possible.
After downloading the project, save the parameterization in STARTER using the function "Copy RAM to ROM" or
with p0977 = 1, so that the incorrect parameter files are overwritten on the CompactFlash card.
Reaction upon F: A_INFEED: NONE (OFF2)
SERVO: NONE (OFF1, OFF2, OFF3)
VECTOR: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
A01047 (F) ACX: Write to parameter error
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: When evaluating the parameters files PSxxxyyy.ACX, PTxxxyyy.ACX, CAxxxyyy.ACX or CCxxxyyy.ACX, saved on
the CompactFlash card, a parameter value was not able to be transferred into the Control Unit memory.
Alarm value (r2124, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: Restore the factory setting using (p0976 = 1) and re-load the project into the drive unit. Operation without any restric-
tions is then possible.
After downloading the project, save the parameterization in STARTER using the function "Copy RAM to ROM" or
with p0977 = 1. This means that the incorrect parameter files are overwritten on the CompactFlash card.
