FlyingSaw
Description of the function blocks
Prepared Solution Servo PLC / ECSxA 1.1 EN 10-14
Inputs (Variable type: VAR_INPUT)
Identifier Data type Value/meaning
bMarkenSync BOOL Activation of the mark synchronisation.
TRUE Mark synchronisation active
FALSE Mark synchronisation not active
dwTi DWORD Flying saw acceleration time. The entry is made in the unit [ms]
dwTif DWORD Flying saw deceleration time. The entry is made in the unit [ms]
dnGapLengthInc DINT Length of the gap. The entry is made in the unit [inc]
bResetError BOOL In case of an error, the block and as a result all active integrators are reset. The variable must be
included in the application's reset handling.
dnOffset_TP DINT Distance between the touch probe signal detected and the initial position of the flying saw. The entry is
made in the unit [inc]
Inputs (Variable type: VAR_OUTPUT)
Identifier Data type Value/meaning
bSync_b BOOL Status signal "Axis synchronised". The signal is output when the axis is moving in phase and speed
synchronism with the master value.
bStatusGap BOOL Status signal "Gap made". The signal is output when a gap has been made in the material.
bFail_b BOOL Status signal "Error". The signal is output when an error has been detected during the synchronous
process.
nSpeedOut_a INT Actual speed for the actual phase integrator
¾ This input is to be connected to the function block MotionControl.
dnPosDiffOut_p DINT
Positional deviation direct for the position controller
¾ This output is to be connected to the function block MotionControl
dnTir DINT
Actual flying saw acceleration time. The signal is needed for the online calculation of the offset value
and must be connected to the function block OffsetCalculation.
