Cause: The zero mark synchronization with the encoder to be emulated was interrupted.
Alarm value (r2124, interpret decimal):
0: The encoder is not in the ready state (e.g. encoder parked)
1: An absolute encoder was connected.
2: The encoder r0479[0...2] interconnected with CI: p4420 is already communicating with another
TM41 (precisely one TM41 can be interconnected with a specific r0479[0...2]).
3: The BICO interconnection to Terminal Module 41 (TM41) was removed (CI: p4420 = 0 signal).
4: The encoder connected with CI: p4420 has carried out an EDS changeover (this operation is not
supported, set p4420 to 0 and interconnect again).
5: The maximum number of revolutions of the encoder was exceeded.
6: Encoder in an invalid state.
7: Encoder in an invalid state.
8: Encoder in an invalid state (the encoder is not parameterized or the interconnected signal source
is not in the cyclic state).
Remedy: None necessary.
- if the encoder changes into the ready state, then a synchronization operation that was previously
interrupted is carried out again.
- if the synchronization was interrupted due to the maximum permissible synchronization duration,
then a new synchronization is not carried out.
- for an absolute encoder, no synchronization is carried out, the zero mark is always output at the zero
revolution of the TM41.
235225 <location>TM: Zero mark synchronization held - encoder not in the ready
state
Message -
value:
Drive object: TM41
Reaction: NONE
Acknowledge: NONE
Cause: The zero mark synchronization with the encoder to be emulated was held.
The encoder is not in the "ready" state.
Remedy: Bring the encoder into the "ready" state.
235226 <location>TM: Tracks A/B are de-activated
Message -
value:
Drive object: TM41
Reaction: NONE
Acknowledge: NONE
Cause: The output of tracks A/B of the Terminal Module 41 (TM41) has been held (frozen).
The encoder emulation of the TM41 hardware is enabled (this is necessary so that no TRI state of the
A/B tracks occurs). The hardware receives a setpoint of zero so that no motion occurs at the A/B
tracks.
Reasons for this alarm:
- CI: p4420 was not interconnected (in this case, the encoder emulation of the hardware is de-acti-
vated)
- the encoder is not in the "ready" state (parking encoder or non-parameterized encoder data set).
- for TM41 there is an additional fault.
Remedy: - establish an interconnection from CI: p4420.
- bring the encoder into the "ready" state.
- remove any TM41 faults.
235227 <location>EDS changeover not supported
Message -
value:
Drive object: TM41
Reaction: NONE
Acknowledge: NONE
Cause: The interconnected encoder has carried out an EDS changeover.
Terminal Module 41 (TM41) does not support this particular application case.
