Specialized specifications for veneer machines  Support dedicated functional parameters for veneer machines:
• The inverter can set the required parameters to operate correctly and accurately with the machine such as: speed, diameter, distance between 2 rollers, cutting thickness, screw pitch …
• The inverter has a group of encoder monitoring functions or specialized parameters such as: current wood core diameter, current tool table displacement, wood cutting length, cutting time 1 plate…
• The inverter has the function of using a lever for 4 positions to control the knife table, limit the screw stroke, receive the alarm sensor signal to return according to the actual system.
• In addition, the inverter can also set the running command and the speed of the cutter if the system uses a cutter and the plate cutting length is accurate with an error of <5mm, the product thickness is correct with an error of ± 2%.
