A01028 (F)
Configuration error
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Reaction:
NONE
Acknowledge:
NONE
Cause:
The parameterization that was downloaded was generated with a different module type (Order No., MLFB).
Remedy:
Save parameters in a non-volatile fashion (p0971 = 1).
F01030
Sign-of-life failure for master control
Message class:
Communication error to the higher-level control system (9)
Reaction:
OFF3 (IASC/DCBRK, NONE, OFF1, OFF2, STOP2)
Acknowledge:
IMMEDIATELY
Cause:
For active PC master control, no sign-of-life was received within the monitoring time.
The master control was returned to the active BICO interconnection.
Remedy:
Set the monitoring time higher at the PC or, if required, completely disable the monitoring function.
For the commissioning software, the monitoring time is set as follows:
<Drive> -> Commissioning -> Control panel -> Button "Fetch master control" -> A window is displayed to set the
monitoring time in milliseconds.
Notice:
The monitoring time should be set as short as possible. A long monitoring time means a late response when the
communication fails!
F01033
Units changeover: Reference parameter value invalid
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
When changing over the units to the referred representation type, it is not permissible for any of the required
reference parameters to be equal to 0.0
Fault value (r0949, parameter):
Reference parameter whose value is 0.0.
See also: p0505 (Selecting the system of units), p0595 (Technological unit selection)
Remedy:
Set the value of the reference parameter to a number different than 0.0.
See also: p0304, p0305, p0310, p0596, p2000, p2001, p2002, p2003, r2004
F01034
Units changeover: Calculation parameter values after reference value change
unsuccessful
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
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.
See also: p0304, p0305, p0310, p0596, p2000, p2001, p2002, p2003, r2004
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 class:
Hardware/software error (1)
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.
