Siemens SINAMICS S210 - PB;PN: Clock Cycle Synchronization Missing for DSC; PB;PN: Clock Cycle Signal Missing When Establishing Bus Communication; PB;PN: Clock Cycle Signal Error When Establishing Bus Communication

Remedy: Set the speed controller sampling times to identical values (p0115[1]).
Note:
PB: PROFIBUS
PN: PROFINET
A01932 PB/PN: clock cycle synchronization missing for DSC
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: There is no clock synchronization or clock synchronous sign of life and DSC is selected.
Note:
DSC: Dynamic Servo Control
See also: p0922, r0922
Remedy: Set clock synchronization across the bus configuration and transfer clock synchronous sign-of-life.
A01940 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.

A01941 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.

PB: PROFIBUS
PN: PROFINET
A01943 PB/PN: clock cycle signal error when establishing bus communication
Message value: -
Drive object: All objects
