During the program run, a variable value assignment or an arithmetic operation has
caused data to be processed in such a way that they have to be converted to another
type. This would lead to the value range being exceeded.
Value ranges of the various variable types:
• REAL: Property: Fractional number with dec. pt., value range: +/-(2-1022-2+1023)
• INT: Property: Integers with signs, value range: +/-(231-1)
• BOOL: Property: Truth value TRUE, FALSE, value range: 0,1
• CHAR: Property: 1 ASCII character, value range: 0-255
• STRING: Property: Character string (max. 100 values), value range: 0-255
• AXIS: Property: Axis addresses, value range: Axis names only
• FRAME: Property: Geometric information, value range: As for axis paths
Overview of type conversions:
• from REAL to: REAL: yes, INT: yes*, BOOL: yes1), CHAR: yes*, STRING: -, AXIS: -,
FRAME: -
• from INT to: REAL: yes, INT: yes, BOOL: yes1), CHAR: if value 0 ...255, STRING: -,
AXIS: -, FRAME: -
• from BOOL to: REAL: yes, INT: yes, BOOL: yes, CHAR: yes, STRING: -, AXIS: -,
FRAME: -
• from CHAR to: REAL: yes, INT: yes, BOOL: yes1), CHAR: yes, STRING: yes, AXIS: -,
FRAME: -
• from STRING to: REAL: -, INT: -, BOOL: yes2), CHAR: only if 1 character, STRING: yes,
AXIS: -, FRAME: -
• from AXIS to: REAL: -, INT: -, BOOL: -, CHAR: -, STRING: -, AXIS: yes, FRAME: -
• from FRAME to: REAL: -, INT: -, BOOL: -, CHAR: -, STRING: -, AXIS: -, FRAME: yes
1) Value <> 0 corresponds to TRUE, value ==0 corresponds to FALSE.
2) String length 0 => FALSE, otherwise TRUE.
3) If only one character.
It is not possible to convert from type AXIS and FRAME nor into type AXIS and FRAME.
- Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Modify the program section such that the value range is not exceeded, e.g. by a modified
variable definition.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 string cannot be converted to AXIS type
%1 = Channel number
%2 = Block number, label
The called function AXNAME - conversion of the transferred parameters of the STRING
type to an axis name (return value) of the AXIS type - has not found this axis identifier in
the machine data.
- Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Please inform the authorized personnel/service department. Check the transferred
parameters (axis name) of the function AXNAME to determine whether a geometry, chan-
nel or machine axis of this name has been configured by means of the machine data:
