Solution
Home the axis/encoder to a valid actual value range.
Adjust the modulo length of the employed encoder.
Solution
Check the device in regard to function, connections and
I/Os.
Solution
Check the device in regard to function, connections and
I/Os.
Check the device in regard to function, connections and
I/Os.
Compare the clock parameters of HW Config
(PROFIBUS line, slave OM for drive or encoder) and the
execution system. Tmapc and servo must be configured
in the same clock cycle time.
(Incorrect parameterization is indicated by reason
0x0080)
