5.11 L_CamSyncIn - synchronous/oversynchronous clutch-in
This FB serves to synchronise a tool (drive) to a running material (relative master speed).
• Types of synchronisation:
• Mark-controlled (touch probe)
• Manually controlled (e.g. manually controlled top cut with flying saw)
• The synchronisation is path-based and functionally corresponds to a subset of the
L_EsClutchPos
clutch module. Synchronous or oversynchronous synchronisations are possible.
• The function corresponds to the "DFRFG" function of the 9300EK servo inverter and additionally
supports a path-controlled clutch-in.
Inputs
Function library: LenzeCam FB is available as of library V01.01.xx.xx!
FB may only be used for firmware as of V3.0!
Runtime software licence:  Motion Control HighLevel  Motion Control TopLevel
Identifier/data type Information/possible settings
dnSpeedIn_s
DINT
Input speed (master speed) as speed in [rpm]
• Example: Material speed of the web with flying saw.
• C05605 indicates the input speed in the real unit of the machine.
dnTpPos_p
DINT
Position of the touch probe sensor in [increments].
• C05606/1 indicates the position in the real unit of the machine.
dnTpTimeLag
DINT
Input for accepting the time stamp
• Connect this input with the output dnTouchProbeTimeLag of the corresponding
touch probe system block.
bTpReceived
BOOL
Input for taking over the status "Touch probe detected"
• Connect this input with the output dnTouchProbeReceived of the corresponding
touch probe system block.
FALSETRUE Touch probe detected.
Note: At the same time, a speed must be applied at the dnSpeedIn_s
input for the clutch-in ramp to be calculated. Otherwise, the clutch-
in process will not be started in the FB.
dnOpenPos_p
DINT
Clutch-in position in [increments]
• Starting position for synchronising.
• Is generally also used as target position for the LS_Positioner system block for re-
positioning.
• C05606/2 indicates the clutch-in position in the real unit of the machine.
