F01912 (N, A) PB/PN: clock cycle synchronous operation sign-of-life failure
Message value: -
Message class: Communication error to the higher-level control system (9)
Drive object: B_INF, ENC, VECTOR_G
Component: None Propagation: LOCAL
Reaction: Vector: OFF1 (OFF3)
Infeed: OFF1
Acknowledge: IMMEDIATELY
Cause: The maximum permissible number of errors in the controller sign-of-life (clock synchronous operation) has been
exceeded in cyclic operation.
Remedy: - physically check the bus (cables, connectors, terminating resistor, shielding, etc.).
- correct the interconnection of the controller sign-of-life (p2045).
- check whether the controller correctly sends the sign-of-life (e.g. create a trace with STW2.12 ... STW2.15 and
trigger signal ZSW1.3).
- check the permissible telegram failure rate (p0925).
- check the bus and controller for utilization level (e.g. bus cycle time Tdp was set too short).

A01920 (F) PROFIBUS: Interruption cyclic connection
Message value: -
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Component: None Propagation: LOCAL
Reaction: NONE
Acknowledge: NONE
Cause: The cyclic connection to the PROFIBUS master is interrupted.
Remedy: Establish the PROFIBUS connection and activate the PROFIBUS master in the cyclic mode.
Note:
If there is no communication to a higher-level control system, then p2030 should be set = 0 to suppress this
message.

Reaction upon F: NONE (OFF1)
Acknowl. upon F: IMMEDIATELY
A01921 (F) PROFIBUS: Receive setpoints after To
Message value: -
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Component: None Propagation: LOCAL
Reaction: NONE
Acknowledge: NONE
Cause: Output data of PROFIBUS master (setpoints) received at the incorrect instant in time within the PROFIBUS clock
cycle.
Remedy: - check bus configuration.
- check parameters for clock cycle synchronization (ensure To > Tdx).
