Outputs
bOpenInstant
BOOL
Positive opening operation of the clutch.
• This input has the second highest priority (after bEnable).
FALSETRUE The master position dnPosOut_p is separated from the master shaft
and stopped via the set ramp.
AxisData Machine parameters
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
• The machine parameters of a master drive can be displayed with the
FB L_SdSetAxisData . In this case, the FB output AxisData must be connected to
this input. ( 510)
Identifier/data type Value/meaning
dnState
DINT
Status (bit coded)
Bit 1 State active
Bit 2 Procedure completed
Bit 3 Acceleration/deceleration phase
Bit 8 Brake/clutch closed
Bit 9 Waiting for clutch process
Bit 15 Error
Bit 16 Starting position is beyond the cycle
Bit 18 No cycle available
Bit 19 Maximum speed = "0"
Bit 21 Input error (e.g. impermissible position jump or inverse direction of
motion)

bInTarget
BOOL
Status signal "Position reached"
TRUE Position reached (clutch or declutch process or positive opening ope-
ration has been completed).
bOpen
BOOL
Status signal "Clutch/declutch process is active"
FALSE Clutch is closed, master position follows the master shaft.
TRUE Master position is synchronised to the master shaft after the clutch
is closed or the master position is shut down after the clutch is ope-
ned.
• dnActPosition_p and dnSetPosition_p are not synchronous!
bAccDec
BOOL
Status signal "Ramp function of the clutch is active"
FALSE Ramp function of the clutch is not active.
• The clutch is closed or the master position is shut down.
TRUE Ramp function of the clutch is active.
• The master position is synchronised or shut down.
• The TRUE signal is pending immediately if the clutch or declutch
process is started via the input bClose.
dnPosOut_p
DINT
Master position output (current position of the master shaft in the cycle) in [inc]
• C05079 indicates the current master position in the real unit of the machine.
