A35224 (N) TM: Zero mark synchronization interrupted
Drive object: TM41
Reaction: NONE
Acknowledge: NONE
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 car-
ried out again.
- if the synchronization was interrupted due to the maximum permissible synchronization duration, then a new syn-
chronization 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.
Reaction upon N: NONE
Acknowl. upon N: NONE
A35225 TM: Zero mark synchronization held - encoder not in the ready state
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.
A35226 TM: Tracks A/B are de-activated
Drive object: TM41
Reaction: NONE
Acknowledge: NONE
Cause: The output of tracks A/B of the Terminal Module 41 (TM41) has been held (frozen). This means:
The encoder emulation of the TM41 hardware is enabled (this is necessary so that no TRI state of the AB tracks
occurs). The hardware receives a setpoint of zero so that no motion occurs at the TM41 AB tracks.
Reasons for Alarm 35226:
- CI: p4420 was not interconnected (in this case, the encoder emulation of the hardware is de-activated)
- 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.
A35227 TM: Zero mark synchronization interrupted - EDS changeover not supported
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.
Remedy: Bring the encoder into the ready state, carry out RAM to ROM and then Power On.
