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%.

• Power range: 3P, 380V, 5.5kW – 500kW.

• The system works well and stably with large and small wood diameters.

• The GD12 inverter can control AM and PM motors, helping the system operate smoothly in quick start, stop and instant reversal.

• Do not use PLC or any other circuit board.

• Precise thickness control with error below 2%, sheet length error less than 5mm.

• GD12 has high overload capacity.

• High reliability with optimal cooling design, C3 filter, works well in both high temperature, low temperature and overvoltage conditions.
