F1220
CU: Basic clock cycle too small
Reaction: NONE
Cause: The parameter for the basic clock cycle is set too short for the number of connected drives.
See also: p0110
Remedy: - Increase the basic clock cycle.
- Reduce the number of connected drives and start commissioning the unit again.
See also: p0110
Acknowl.: Immediate
F1221
CU: Basic clock cycle too short (application cannot maintain its clock cycle)
Reaction: NONE
Cause: The application cannot maintain its clock cycle.
Application runtime is simply too long for the particular clock cycle, or the remaining system
time is not sufficient for the application.
Remedy: Increase basic clock cycle of DRIVE-CLiQ communication.
Acknowl.: Immediate
F1250
CU: CU-EEPROM Initialization
Reaction: NONE
Cause: Error during initialization of the EEPROM on the control unit.
Fault value 1: Read error RO structure
(r0949): 2: Checksum error RO structure
3: Block setup error RO data
Remedy: POWER ON durchführen
Acknowl.: POWER ON
F1255
CU: Option-Slot-EEPROM Initialization
Reaction: NONE
Cause: Error on initializing the option slot EEProm.
Fault value 1: Read error RO structure
(r0949): 2: Checksum error RO structure
3: Block structure error RO data
Remedy: POWER ON durchführen
Acknowl.: POWER ON
F1300
Topology: No topology detected or specified
Reaction: NONE
Cause: The number of components connected via DRIVE-CLiQ (incl. the TBxx) or the target device
topology type is zero.
See also: r0098, p0099
Remedy: Connect topology components via DRIVE-CLiQ and switch on CU again.
Accept r0098 in p0099.
See also: p0099
Acknowl.: Immediate
F1305
Topology: Component number missing
Reaction: NONE
Cause: The component number from the topology has not been parameterized (p0121(for AFE only,
s.p0107), p0131(for Servo/Vector drives only, see. p0107), p0141, p0151, p0161).
See also: p0121, p0131, p0141, p0142, p0151, p0161, p0185, p0186, p0187, p0188, p0189
Fault value Fault value contains relevant dataset number.
(r0949): Fault also occurs if speed sensor was configured (p0187 ... p0189) but no component
number exist for them.
The fault value contains the drive data set number in this case, plus. 100*sensor number (e.
g. 3xx, if no component number is entered for the third sensor (p0189) in p0141).
Remedy: Enter the missing component number or remove component and restart commissioning.
