FlyingSaw
Description of the function blocks
Prepared Solution Servo PLC / ECSxA 1.1 EN 10-2
Inputs (Variable type: VAR_INPUT)
Identifier Data type Value/meaning
bAbort BOOL This input triggers the cancelling of positioning. The input is handled within the application in the
MachineControl. The flying saw is positioned in the initial position during return movement.
FALSE ->TRUE Cancel the positioning
Profile DINT Positioning profile
¾ Data structure; the elements of the structure describe the complete profile
byMotionControlMode DINT
Positioning mode
¾ In the application absolute positioning is performed during movement to the initial position
and constant travel during manual control.
Positioning modes used:
0 Absolute positioning
2 Continuous constant travel
bMotorInvert BOOL Entry of the motor mounting direction
FALSE not inverted
TRUE inverted
bExternSetValuesEnable BOOL Switch to external setpoints for synchronisation
¾ The external setpoints are looped through 1:1 to the related outputs.
nSpeedOutSaw INT Setpoint for the speed for the synchronisation
¾ For this setpoint to be actively switched to the interface, the variable
bExternSetValuesEnable must be set to TRUE.
¾ nSpeedOutSaw -> MCTRL_nNSet_a
dnPosDiffOutSaw DINT Setpoint for the positional deviation for the synchronisation
¾ For this setpoint to be actively switched to the interface, the variable
bExternSetValuesEnable must be set to TRUE.
¾ dnPosDiffOutSaw -> MCTRL_dnPosSet_p
bHomingMark BOOL Homing switch
bMCTRL_bActTPReceived_b BOOL Input for the MCTRL touch probe
dnMCTRL_dnActIncLastScan DINT Phase difference in [inc] between latching time and starting time for the task
nMCTRL_nNAct_v INT Actual speed for the actual phase integrator
¾ The input is to be connected to the system variable MCTRL_nNAct_v (speed value for
the feedback system) in SB MCTRL.
bDCTRL_bCInh_b BOOL Signal for the controller inhibit
¾ The input is to be connected to the system variable DCTRL_bCInh_b in SB DCRTL.
Inputs (Variable type: VAR_INPUT)
Identifier Data type Value/meaning
bMCTRL_bQspOut_b BOOL Drive is in quick stop
¾ This input is to be connected to the system variable MCTRL_bQspOut_b in SB
MCTRL.
bReset BOOL Reset positioning
Axis AXIS_REF
Machine parameters
¾ Data structure with elements that contain the machine parameters in the internal
measuring system.
¾ Connect this input to a global variable written by the FB L_MCMachineData.
