F4002: Failure of a consumer connection

We try to connect to a CTRL-X drive type XCS (see picture). We are using a Codesys soft PLC with softmotion on a laptop. Codesys program V3.5 SP19 Patch 1 is used for program. We have connection with the drive in the program. We can read out the servo position. 

We get an error on the drive 'F4002: Failure of a consumer conection'. Drive is in operation mode.

How can we get rid of this failure? Master settings are added in the pictures. Drive parameter file in attachment.
