Peak plus – maximum allowed peak power reached during the welding process (in W)
Peak minus– minimum allowed peak power reached during the welding process (in W)
Last pk Power – peak power of the last working process (in W)

Delay, Hold and Afterburst window:
Delay – after the start signal, the generator delays starting with the set value of the delay (in seconds)
Hold – the generator delays with the set hold value before executing Afterburst (in seconds)

Standard communication interface ModBus RTU over RS 485

The generator has a standard communication interface ModBus RTU over RS 485.  To connect to a PC you should use our adapter, USB or RS 232 to RS 485 optically isolated.


Communication user interface INFO

The User interface allows real-time diagnostic analysis of Modbus communications between the FFT (Fixed Frequency Tracking) generator and the PC or PLC. We submit easy-to-use powerful user interface together with all FFT ultrasonic generators.

The User Interface allows the user

  • To have all working limits of the transducer,
  • To set system configuration and working process,
  • To customize I/O configuration,
  • To perform system diagnostics,
  • To navigate easy by simple tab structure.

CONTROL Tab— to have all parameters and settings from the generator and to know the working limits of the generator. In the working range of the generator should be selected safe limits for working with the transducer.

SCAN Tab — After the scanning procedure, the diagram shows the actual operating parameters of the transducer- current characteristics and phase characteristic.

WELDING Tab— Allows the user to setup welding parameters— peak power, energy, time, delay, hold and afterburst.

OSCI Tab— Allows for viewing and displays graphically the data of the working process, including frequency, output current, phase, amplitude, power and PWM.
