Inputs
Global variables (Variable type: VAR_GLOBAL)
Name Data type Value/Meaning
g_dnSetCuttingLength DINT Cutting length in 0.0001[m_units]
g_dnSetRejectLength DINT Reject length in 0.0001[m_units]
g_dnSetTestLength DINT Test length in 0.0001[m_units]
g_dnSetStartStopLength DINT Start/stop length in 0.0001[m_units]
g_dnCirumferenceSlave DINT Cutting circle circumference of knife drum in 0.0001[m_units]:
Example: The cutting circle diameter of the knife drum is 127.3240[mm]. The
circumference is calculated by multiplying the diameter by π (= 3.141592654 …)
and results in a value of 400.0000[m_units]. You should therefore assign a value of
4000000 to variable g_dnCircumferenceSlave.
Note: Do not enter the synchronous cutting length here (this may not be the same
as the cutting circle circumference on knife drums with multiple knives). Always
enter the full circumference of the knife cutting circle here.
g_dnSyncAngle DINT Cutting angle for which the knife has to run in synchronism with the material in
0.0001[s_units]
• Example: A dnSyncAngle value = 300000 corresponds to a cutting
angle of 30.0000[s_units] = 30.0000 [°].
• If you use this variable, to avoid inconsistencies, do not write variable
g_dnSyncAngle_p!
g_dnSyncAngle_p DINT Cutting angle for which the knife has to run in synchronism with the material in [incr.]
• If you use this variable, to avoid inconsistencies, do not write variable
g_dnSyncAngle!
Selection of type of motion for the asynchronous motion phase:
0
Second order polynomial (linear speed
ramps)
1 Fifth order polynomial
2 Sloping sine line
g_byProfileTypeCalculation BYTE
The input values are limited to this value range!
g_nAdjustCuttingSpeed INT Adaptation of the cutting speed. The value is entered in %.
• 100% = 16384
