PROFIBUS: Interruption, cyclic connection
Reaction:
NONE
Acknowledge:
NONE
Cause:
The cyclic connection to the PROFIBUS master is interrupted.
Remedy:
Set up the PROFIBUS connection and activate the PROFIBUS master in the cyclic mode.
Reaction upon F:
NONE (OFF1)
Acknowledge
IMMEDIATELY
upon F:
A01921 (F)
PROFIBUS: Clock cyc synchron
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 the bus configuration:
- parameters for clock synchronization: Ensure the instant in time for setpoint acceptance To > data exchange time

PROFIBUS: Current controller clock cycle for clock synchronous operation, not the
same
Reaction:
NONE
Acknowledge:
NONE
Cause:
The current controller clock cycle of all drives must be set the same for the clock synchronous PROFIBUS.
Alarm value (r2124, decimal):
Number of the drive object with the different current controller clock cycle.
Remedy:
- set current controller clock cycles to identical values (p0115[0]).

A01931
PROFIBUS: Speed controller clock cycle for clock synchronous operation, not the
same
Reaction:
NONE
Acknowledge:
NONE
Cause:
The speed controller clock cycle of all drives must be set the same for the clock synchronous PROFIBUS.
Alarm value (r2124, decimal):
Number of the drive object with the different speed controller clock cycle.
Remedy:
- set the speed controller clock cycles the same (p0115[1]).
