Cause: The cyclic connection to the PROFIBUS master is interrupted.
Remedy: Establish the PROFIBUS connection and activate the PROFIBUS master in the cyclic mode.
201921 <location>PROFIBUS: Receive setpoints after To
Message -
value:
Drive object: All objects
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).
Note:
To: Time of setpoint acceptance
Tdx: Data exchange time
201930 <location>IF1: PB/PN current controller clock cycle clock cycle
synchronous not equal
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The current controller clock cycle of all drives must be set the same for the clock cycle synchronous
operation.
Alarm value (r2124, interpret decimal):
Number of the drive object with different current controller clock cycle.
Remedy: Set current controller clock cycles to identical values (p0115[0]).
Note:
IF1: Interface 1
PB: PROFIBUS
PN: PROFINET
See also: p0115
201931 <location>IF1: PB/PN speed controller clock cycle clock cycle
synchronous not equal
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The speed controller clock cycle of all drives must be set the same for the clock cycle synchronous
operation.
Alarm value (r2124, interpret decimal):
Number of the drive object with the different speed controller clock cycle.
Remedy: Set the speed controller clock cycles the same (p0115[1]).
Note:
IF1: Interface 1
PB: PROFIBUS
PN: PROFINET
See also: p0115
201932 <location>IF1: PB/PN clock cycle synchronization missing for DSC
Message -
value:
Drive object: SERVO, TM41
Reaction: NONE
Acknowledge: NONE
