Solution
Connect a suitable device. Check the device (I/Os).
Check the topological configuration in HW Config.
Compare the configuration in HW Config and the tech-
nology object.
Solution
Check the device in regard to function, connections and
I/Os.
Compare the encoder type in the drive or encoder pa-
rameter P979 with the configuration data of the technol-
ogy object.
Encoder reports error for the zero mark monitoring (error
code 0x0002 in Gx_XIST2, see PROFIDrive profile).
Check the system for electromagnetic compatibility
(EMC).
Locate the cause of the error in the connected drive or
encoder. Check whether the alarm was possibly trig-
gered by a startup action on the drive or encoder.
