Class 5: Machine Data Errors
The diagnostic interrupt is triggered only when there is an error in the system data
block (SDB). Data machine data do not lead to an error reaction.
No. Meaning Diagnostic
Interrupt
5
Error in hardware interrupt setting Yes
Cause
You have attempted to select a hardware interrupt
that the module does not support.
6
Wrong minimum edge-to-edge distance (FM 451) Yes
Cause
You have entered a value < 0 or > 10
9
µm as the
minimum edge-to-edge distance.
7
Wrong system of units Yes
Cause
The value for the system of units is outside the
permitted range of 1 to 4 and 6.
8
Incorrect axis type Yes
Cause
You have specified neither 0 nor 1 as the axis type
9
Incorrect rotary axis end Yes
Cause
The value for the end of the rotary axis is outside the
permitted range of 1 to 10
9
µm or 1 to 10
8
µm
(depending on the resolution).
10
Incorrect encoder type Yes
Cause
The value for the encoder type is outside the
permitted range of 1 to 4.
11
Incorrect distance per encoder revolution Yes
Cause
The value for distance /encoder revolution is outside
the permitted range of 1 to 10
9
µm (regardless of the
resolution).
13
Incorrect increments per encoder revolution (see Section 8.5,
page 8-15)
Yes
14
Incorrect number revolutions (see Section 8.5, page 8-15) Yes
15
Incorrect baud rate Yes
Cause
You have specified a baud rate outside the permitted
range of 0 to 3.
16
Incorrect reference point coordinate Yes
Cause
The coordinate is outside the range of –100m to
+100m or –1000m to +1000m (depending on the
resolution).
Linear axis: The coordinate is outside the working
range.
Rotary axis The coordinate is higher than the end of
the rotary axis or < 0.
