If1: Pb/Pn Clock Cycle Synchronization Missing For Dsc; If1: Pb/Pn Clock Cycle Synchronism Not Reached; Pb/Pn Clock Cycle Signal Missing When Establishing Bus Communication - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
201932 <location>IF1: PB/PN clock cycle synchronization missing for DSC
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: There is no clock cycle synchronization and DSC is selected.
Note:
DSC: Dynamic Servo Control
Remedy: Set the clock cycle synchronization when configuring the bus.
201940 <location>IF1: PB/PN clock cycle synchronism not reached
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing
telegram. It was not possible to synchronize to the clock cycle specified by the master.
- the master does not send a clock synchronous global control telegram although clock synchronous operation was
selected when configuring the bus.
- the master is using another clock synchronous DP clock cycle than was transferred to the slave in the parameterizing
telegram.
- at least one drive object has a pulse enable (not controlled from PROFIBUS/PROFINET either).
Remedy: - check the master application and bus configuration.
- check the consistency between the clock cycle input when configuring the slave and clock cycle setting at the master.
- check that no drive object has a pulse enable. Only enable the pulses after synchronizing the PROFIBUS/PROFINET
drives.

IF1: Interface 1
PB: PROFIBUS

201941 <location>IF1: PB/PN clock cycle signal missing when establishing bus
communication
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing
telegram. The global control telegram for synchronization is not being received.
Remedy: Check the master application and bus configuration.

IF1: Interface 1
PB: PROFIBUS
