A01931
PB/PN speed controller sampling time clock cycle synch. not equal
Drive object:
All objects
Cause:
The speed controller sampling time 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 sampling time.
Remedy:
Set the speed controller sampling times to identical values (p0115[1]).
Note:
PB: PROFIBUS
PN: PROFINET

A01940
PB/PN clock cycle synchronism not reached
Drive object:
All objects
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.

PB: PROFIBUS
PN: PROFINET
A01941
PB/PN clock cycle signal missing when establishing bus communication
Drive object:
All objects
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.
Note:
PB: PROFIBUS
PN: PROFINET
A01943
PB/PN clock cycle signal error when establishing bus communication
Drive object:
All objects
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 being irregularly received.
-.the master is sending an irregular global control telegram.
- the master is using another clock synchronous DP clock cycle than was transferred to the slave in the
parameterizing telegram.
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.

PB: PROFIBUS
PN: PROFINET
