Description
Possible reason for error
F.921
Internal 15 V voltage incorrect
• Hardware defect
F.922
E-Stop chain not complete
Not all E-STOP inputs are separately jumpered although the entire E-Stop chain is jumpered
• Redundant checking of the E-Stop chain tripped
F.925
Testing of the third shutdown
method failed
• defective hardware
F.928
Faulty input testing
• The testing of an cyclic tested input was not successful
• The connected device is not working
• The cable connection between the connected device and the controller is broken
F.92A
If the motor wiring test is activated
by P.112 the wiring will be tested
during system tests.
• min. one of the motor cables is not good or nor connected
• Motor cable damaged
• Motor damaged
F.930
External watchdog incorrect
• Defective hardware or noise-saturated environment
F.931
ROM error
• Wrong EPROM code
• Defective hardware or noise-saturated environment
F.932
RAM error
• Defective hardware or noise-saturated environment
F.933
Wrong frequency of CPU
• The clock frequency of the processor is wrong
F.935
Stack error
• User-Stack or System-Stack overflowed
• Possible software error due to recursive invocations (e.g. profile)
F.942
RAM Error of I/O Processor
• RAM Error of I/O Processor
F.960
Faulty parameter checksum
• New EPROM version with different parameters
• Controller not yet initialized
F.961
Checksum from calibration values
etc.
• New EPROM version with different EEPROM structure
• Controller not yet initialized
F.962
Converter parameters not
plausible
• New EPROM version
• Controller not yet initialized
F.964
Program version / manufacturer
code
• New EPROM version
• Controller not yet initialized
F.965
Faulty door cycle counter with
active emergency opening
• The door cycle counter does not count or is faulty. Because of this no emergency opening testing can be done.
F.966
Hardware unknown
• A wrong software was programmed to the controller
• The programmed software does not know the hardware version
• The controller hardware is broken
F.968
Programming error with Real time
clock
• The clock is not programmed plausible
F.969
Internal error Real time clock
• The clock has an error → make a reset
F.970
Plausibility parameter block error
• New EPROM version
• Controller not yet initialized
• Some parameter is implausible
