Corrected from:
Servo inverter i950 with TA Cia402-Advanced: (no change intended)
Response of the new version:
The described dead time in the setpoint generation is present in the i950 with TA Cia402-Advanced due to the principle. Accordingly, this dead time cannot be eliminated in a simple way.
An adjustment of the dead times between the device series would only be theoretically possible by changes in the other device series.
Such interventions in the internal time structure of devices are associated with high risks, therefore no changes are planned with regard to the behavior described here.

What happens?
When operating an electrical shaft (master-slave connection), the synchronization of the axes is not given.
Due to the larger dead time of approx. 1.7 ms in the setpoint processing of the i950 with TA CiA402-Advanced, a correspondingly large and speed-proportional position offset to the other drives of the electrical shaft occurs.
When does the behaviour occur?
Operation of the Servo Inverter i950 TA CiA402-Advanced together with devices Servo Inverter i700 or i950-Base in the same electrical shaft application.
Which products are affected?
Servo Inverter i950 with TA Cia402-Advanced
Short-term measures / evaluation / recommendations:
For the electric shaft application, use only drive controllers of the same type.
These have the same dead time in the setpoint processing, so that the described position offset does not occur between the drives.
