WORD
Output of the MCK control word 1 & 2
• For transfer to the
system block.
• For a detailed description of the individual control bits, see chapter "
bPosSetDataValid
BOOL
Status signal "Position conversion completed, data consistent"
• This output is permanently set to TRUE if the g"0: dnPosOut_p=dnPosIn_p" mode
has been set for the position calculation in
and no modulo measuring
system exists.
• If a cycle length has been set in
, a calculation is made under the
following conditions without an immediate setting of bPosSetDataValid:
- Position specification is higher than or equal to the cycle length.
- Position specification is negative.
For a correct positioning process, the bPosSetDataValid = TRUE status is required.
TRUE Conversion of the target position from [units] into [increments] has
been completed.
• The travel profile data are valid and the profile is ready to start.
dnPosSetOut_p
DINT
Output of the target position in [increments]
• Observe the bPosSetDataValid status output!
wFailState
WORD
Result of the plausibility check
• Result is bit coded:
Bit 0 Invalid operating mode selection
• "1" ≡ The selected operating mode is not defined/invalid.
Bit 1 Invalid positioning mode selection
• "1" ≡ The selected positioning mode is not defined/invalid.
Bit 2 Invalid profile number selection
• "1" ≡ The selected profile number refers to a profile data set that
does not exist.
Bit 3 Reserved
...
Bit 15
bFail
BOOL
FALSE Okay, no error
TRUE
