Outputs
bOpenInstant
BOOL
Positive opening operation of the clutch (for emergency situations)
• This input has a higher priority than the input bOpen.
FALSETRUE The dnPosOut_p output position is separated immediately from the
dnPosIn_p master position and brought to standstill within the dece-
leration time set in C05482.
• It is not possible to abort the positive opening operation early.
• If the dnPosOut_p output position is at standstill, the output
bOpenDone is set to TRUE.
• Afterwards a clutch-in process by a FALSE-TRUE edge at the input
bOpen can only be effected again after the input bOpenInstant
has been reset to FALSE.
bReset
BOOL
Reset declutch process.
• This function allows for a "hard clutch-in" and can be used for certain interruption
mechanisms or for starting up the machine.
• The reset of the declutch process should be only effected during controller inhibit
or a decoupled setpoint path.
• This input has the highest priority.
TRUE The dnPosOut_p output position is set immediately to the dnPosIn_p
master position.
• The output bClosed is set to TRUE.
AxisData Machine parameters
• If the FB is to relate to the measuring system of the drive axis, connect this input
to the output DI_AxisData of the LS_DriveInterface SB for accepting the machine
parameters of the drive/motor.
• If the FB within a cam application is to relate to the measuring system of the mas-
ter selection (master), connect this input to the output XAxisData of
the L_CamProfiler FB instead. ( 162)
• If this input is left unconnected, the position values are processed with the follo-
wing resolution: 1 encoder revolution ≡ 2 16 increments
Identifier/data type Value/meaning
dnPosOut_p
DINT
Output position in [increments]
• C05487 indicates the output position in the real unit of the machine.
dnSpeedOut_s
DINT
Output speed given as speed in [rpm]
• C05488 indicates the output speed in the real unit of the machine.
bClosed
BOOL
Status signal to the clutch status
FALSE The clutch is open, or an active clutch-in/declutch process is active.
• The output position is at standstill or within an acceleration/de-
celeration phase.
TRUE The clutch is closed.
• Output position dnPosOut_p and input position dnPosIn_p are
synchronous.
bOpenDone
BOOL
Status signal "Declutch process completed"
TRUE The declutch process activated via bOpen or bOpenInstant has been
totally completed; a clutch-in process can be effected again.
bInTarget
BOOL
Status signal "Standstill position reached"
TRUE The standstill position dnOpenPosition_p after a declutch process ac-
tivated via bOpen has been reached.
bError
BOOL
"Error" status
TRUE An error has occurred (group signal).
• For details see display parameters C05489.
