C05339 Status messages: Status (bit coded)
• Bits that are not itemised are re-
served for future extensions.
• The bError error output will only
be set to TRUE if an error message
(bit 16 ... 31) is issued.
• Bit 31 is the default setting if one
or more other error bits (bit 16 ...
30) are set.
bits8 Clutch closed
bits9 Declutch position reached
bits14 Internal position overflow during
declutch process
Bit15 Internal position overflow during
clutch-in process
Error messages:
bit16 Position is beyond the cycle
bits23 Invalid axis data structure
bits31 General error

Note!
A clutch-in or declutch process may last up to 10 seconds, depending on the paramete-
rised resolution of an encoder revolution in the machine parameters copied to the FB
(AxisData).
Example: If the maximum resolution of 24 bit/encoder revolution is set, the clutch-in
path may be too long after only 2 s at maximum speed (internal position gets lost).
• In this case, clutching-in is executed via an emergency time ramp. This changes the
course of speed and position during the clutch-in and declutch process.
• During the declutch process, you cannot stop at the standstill position dnOpenPos_p
anymore! The time ramp, however, is maintained and the standstill position is within
the cycle.
• An internal position overflow during the clutch-in/declutch process is displayed in
C05339 via bit 14 and bit 15.
