F01034 Units changeover: Calculation parameter values after reference value change
unsuccessful
Message value: Parameter: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The change of a reference parameter meant that for an involved parameter the selected value was not able to be re-
calculated in the per unit representation. The change was rejected and the original parameter value restored.
Fault value (r0949, parameter):
Parameter whose value was not able to be re-calculated.

p2002 (Reference current), p2003 (Reference torque), r2004 (Reference power)
Remedy: - Select the value of the reference parameter such that the parameter involved can be calculated in the per unit
representation.
- Technology unit selection (p0595) before changing the reference parameter p0596, set p0595 = 1.

A01035 (F)

ACX: Parameter back-up file corrupted

Message value: %1
Message class: Hardware / software error (1)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: When the Control Unit is booted, no complete data set was found from the parameter back-up files. The last time that
the parameterization was saved, it was not completely carried out.
It is possible that the backup was interrupted by switching off or withdrawing the memory card.
Alarm value (r2124, interpret hexadecimal):
ddccbbaa hex:
aa = 01 hex:
Power up was realized without data backup. The drive is in the factory setting.
aa = 02 hex:
The last available backup data record was loaded. The parameterization must be checked. It is recommended that
the parameterization is downloaded again.
dd, cc, bb:
Only for internal Siemens troubleshooting.
See also: p0971 (Save drive object parameters), p0977 (Save all parameters)
Remedy: - Download the project again with the commissioning software.
- save all parameters (p0977 = 1 or "copy RAM to ROM").

Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
F01036 (A)

ACX: Parameter back-up file missing

Message value: %1
Message class: Hardware / software error (1)
Drive object: All objects
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: When downloading the device parameterization, a parameter back-up file PSxxxyyy.ACX associated with a drive
object cannot be found.
Fault value (r0949, interpret hexadecimal):
Byte 1: yyy in the file name PSxxxyyy.ACX
yyy = 000 --> consistency back-up file
yyy = 001 ... 062 --> drive object number
