Overview of Alarms
Cause: The frequency of the pulses at the measuring probe input is too high.
Fault value (r0949, decimal):
1: DI/DO 9 (X122.8)
2: DI/DO 10 (X122.10)
4: DI/DO 11 (X122.11)
8: DI/DO 13 (X132.8)
16: DI/DO 14 (X132.10)
32: DI/DO 15 (X132.11)
1001: DI/DO 9 (X122.8) initialization error
1002: DI/DO 10 (X122.10) initialization error
1004: DI/DO 11 (X122.11) initialization error
1008: DI/DO 13 (X132.8) initialization error
1016: DI/DO 14 (X132.10) initialization error
1032: DI/DO 15 (X132.11) initialization error
Remedy: Reduce the frequency of the pulses at the measuring probe input
201150 <location>CU: Number of instances of a drive object type have been
exceeded
Reaction: NONE
Acknowledge: POWER ON
Cause: The maximum permissible number of instances of a drive object type was exceeded.
Fault value (r0949, decimal):
Byte 1: Drive object type (p0107).
Byte 2: Max. permissible number of instances for this drive object type.
Byte 3: Actual number of instances for this drive object type.
Remedy: - power-down the unit.
- suitably restrict the number of instances of a drive object type by reducing the number of
inserted components.
- re-commission the unit.
201205 <location>CU: Time slice overflow
Reaction: OFF2
Acknowledge: POWER ON
Cause: Insufficient processing time is available for the existing topology.
Fault value (r0949, hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - reduce the number of drives.
- increase the sampling times.
201210 <location>CU: Basic clock cycle selection and DRIVE-CLiQ clock cycles
do not match
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The parameter to select the basic clock cycle does not match the drive topology. Drives
connected to the same DRIVE-CLiQ port of the control unit have been assigned different
basic clock cycles.
Fault value (r0949, decimal):
The fault value specifies the parameter involved.
See also: p0111
Remedy: Only those drive objects may be connected to the same DRIVE-CLiQ socket of the control
unit that should run with the same basic clock cycle. For example, active line modules and
motor modules should be inserted at different DRIVE-CLiQ ports as their basic clock cycles
and current controller clock cycles are generally different.
