Timberex Group sawing line updating with Invertek Drive variable frequency drive

2021-05-31 09:37:51

At the beginning of 2021, the long-standing partner of ZTF “LĀSMA” — Timberex Group, undertook a renewal of the management of the sawing line by equipping it with Invertek Drives frequency drives.

The sawing line was equipped with:

  • P2 series variable frequency drive with a power of 75 kW
  • P2 series variable frequency drive with a power of 55 kW
  • ECO series variable frequency drive with power of 45 kW (2 pcs)

The advantage of Invertek variable frequency drives is that it is possible to create a simplified control system using the integrated Master/Slave function provided by the Modbus protocol (see figures).

Using the integrated functions of the Invertek variable frequency drive -  the 4 engines of the boarding line used to provide saws and conveyor delivery are driven from a single drive.

In this system, the potentiometer and the START/STOP button are added to the 75 kW P2-series drive,, as well as the engine parameters are defined. The 75 kW converter is used in standard operating mode and will perform the role of the Master drive in the system.

The ECO series and 55 kW P2 series converter is used in the Slave mode, each is defined in a different address in the serial communication configuration, and the starting/braking times are changed as needed, and the factor by which it is possible to change the running speed of each frequency converter proportionally to the Master drive.

Customer benefits using the following system:

  • Easy installation (force input/output + Ethernet cable)
  • Simpler Control Panel, 4 engines are driven with a single potentiometer and switch
  • Widely adjustable control parameters to get the results required
  • By means of the ECO series drive, the production of reactive energy is reduced significantly
