Pos.ref.val. and act.val. output via the bus interf. lim-
ited. Suppl. info \%X
Cause
The output of the position reference value, position actual value or posi-
tion correction value is parameterized via PROFIBUS or the bus inter-
face. However, the value to be output can no longer be represented in 32
bits and was therefore limited to the maximum values 0x7fffffff or
0x80000000.
The traversing range which can be displayed is given by
Lower limit: – 2147483648 * P896 / P884
Upper limit: + 2147483647 * P896 / P884
The supplementary information explains which process data has violated
the lower or upper limit:
Supplementary info process data
xx1 Position reference value Xset (No. 50208) Upper limit exceeded
xx1 Position reference value Xset (No. 50208) Lower limit fallen below
x1x Position actual value Xact (No. 50206)
x2x Position actual value Xact (No. 50206)
1xx Position correction value dxKorr (No. 50210) Upper limit exceeded
2xx Position correction value dxKorr (No. 50210) Lower limit fallen below
Remedy
– Move drive back e.g. by jogging in the representable traversing
range.
– Adapt the lower and upper limit to the required traversing range using
P884 and P896.

Reference cam not reached
Cause
After starting the reference point approach, the axis moves through the
distance in P0170 (max. distance to the reference cam) without finding
the reference cam.
Remedy
– Check the "reference cam" signal
– Check P0170
– If it is an axis without reference cam, then set P0173 to 1

Reference cams too short
Cause
When the axis moves to the reference cam, and does not come to a
standstill at the cam, then this error is signaled, i.e. the reference cam
is too short.
Remedy
– Set P0163 (reference point approach velocity) to a lower value
– Increase P0104 (maximum deceleration)
– Use larger reference cam
