Overview of Alarms
SIMODRIVE alarms
300202 Axis %1 drive %2 CRC error, error location %3
Parameters: %1 = NC axis number
%2 = Drive number
%3 = Error location
Definitions: The cross-check (CRC) has detected an access error in a write/read cycle. All bus accesses are not
controlled directly by the processor but they are handled by special ASICs. They transfer not only the
required data but also cross-checks for the write/read data and the addresses.
The error can occur in conjunction with a power failure of one or several drive modules. A hardware
fault might also be the cause (ASICs, bus, drive modules).
Reaction: NC not ready.
The NC switches to follow-up mode.
Mode group not ready, also effective for single axes
NC Start disable in this channel.
Axes of this channel must be re-referenced.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. If the alarm has occurred in conjunction
with a power failure, this cause of failure must be eliminated. Otherwise, please contact the system
support for A&D MC products, SIEMENS AG, through the Hotline (tel.: see alarm 1000).
Program Switch control OFF - ON.
Continuation:
300300 Axis %1 drive %2 boot error, error code %3
Parameters: %1 = NC axis number
%2 = Drive number
%3 = Error code
Definitions: Error occurred while starting up the displayed drive. (Example: Drive signals timeout).
Meaning of the error code:
- 0..5: Timeout while waiting for the acknowledgement from the drive in the displayed state
- 10: No signal from drive CPU (possibly defective module)
Safety Integrated special case: If the axial machine data $MA_SAFE_FUNCTION_ENABLE of at least
one axis is not zero, then the occurrence of this alarm with error code 5 can mean that the PLC, after
the timeout PLC_RUNNINGUP_TIMEOUT, has not started the cyclic operation. Synchronization of
the drive and the PLC is required because in cyclic operation of the drive, data transmission between
the PLC and the drive is monitored.
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. You can try to power the system up
again. The search for the precise cause of error can only be performed by the development team. The
displayed status code is always needed for this.
