No. Meaning
9 Axis not synchronized
Cause
Target/distance cannot be positioned
10
Cause
Reference point approach not possible
17
Cause
Relative or absolute incremental approach not possible
18
Cause
Switch-off difference not greater than 1/2 target range for
19
incremental dimension number 255
Cause
20 Travel in specified direction illegal
Cause
Class 4: Data Errors
Data errors are detected synchronous to operator input/commands. Data errors do
not lead to an error reaction.
No. Meaning
Specified increment too large
6
Cause
Bad zero offset (FM 451)
10
Cause
FM 351 Positioning Module
C79000-G7076-C351-02
The "incremental approach" is only possible with an
axis that is already synchronized.
The distance between the current actual position
and the specified target is less than the switch-off
difference
An SSI encoder was connected.
The incremental dimension is invalid.
The switch-off difference for incremental dimension
255 is less than half the target range
Not enough distance to software limit switch
The value is not within "100 m or "1000 m. The
distance/ target must be greater than the travel
range
On a rotary axis, the coordinate must be > = 0 and
less than the end of the rotary axis.
The zero offset is more than " 100m or " 1000m.
The software limit switches are outside the travel
range (–100m...+100m or –1000m...+1000m) after
setting the zero offset.
Rotary axis: The value of the zero offset is higher
than the end of the rotary axis.
