Appendix B: Basic Parameter Settings
Extrusion Mode:
You need an extruder signal that is proportional to the extruder speed to operate in the
Extrusion - Proportional mode. You can use any of the following:
• Frequency signal (must be 12 VDC square wave)
• 0 - 10 VDC signal
• 0 - 20 mA current signal
Determine the frequency output in the lower working area (A) of the extruder. Record the
data. Min. input frequency = __________ Hz
Determine the frequency output in the upper working area (B) of the extruder. Record the
data.
Max. input frequency = __________ Hz
If a voltage signal is available (0 - 10 VDC) calculate the frequency output of the extruder for
the lower / upper working area using the formula:
Frequency [Hz] = Input voltage [V] x 10000 [Hz]
10 [V]
Note the data:
Min. input frequency = __________ Hz
Max. input frequency = __________ Hz
If a current signal is available (0 - 20 mA) calculate the frequency output of the extruder for
the lower / upper working area using the formula:
