CS-I - Medium Frequency - Inverter

RWMA Member
  • Overview

    • Power inverter using IGBT technology for medium–frequency output, programmable via terminal or via remote field bus.
    • Software availability to drive DC transformers (Square wave output) or to drive AC transformers (Sine wave current output).
    • Frequency set by the user from 1 KHz to 5 KHz in case of DC Transformers or 50 to 1000 Hz in case of AC transformers.
    • User selectable primary or secondary current measurement. - Six different modes of current regulation are available:
    • Duty fixed percentage D‰
    • Duty percentage with primary voltage compensation, V‰
    • Constant Current IK • Constant Power PK • Constant Energy EK
    • Adaptive AD
    • Welding current set by external voltage reference 0-10V or Field Bus.
    • Gain adjustable current regulation loop.
    • Cycle management of spot welding machines or rollers welding machines set by user.
    • Time management in periods or in milliseconds.
    • Electrical insulation of input and output sections.
    • Setup and execution of 64 programs, called by external input, internal, sequential or associated with the start cycle IC1 or IC2.
    • Point to point serial communication line RS232, used to connect a printer or a personal computer or a network serial communication line RS485  Availability of expansion of communication:
      • Profibus
      • DeviceNet
      • CANopen
      • Modbus/RTU
      • Profinet/IO
      • EtherN/IP
      • EtherCAT
      • Modbus/TCP
    • Start cycle with dual push buttons (dual input) or pedals (single input). - Monitoring (Quality Control) of the limits of the welding current in spot-weld and in rolls weld mode.
    • Programmable function of continuous current increment to compensate electrodes wears under variable curve up to four pairs of electrodes(four transformers).
    • Welds counter with alarm and lock function.
    • Four solenoid valves flexibly associated to pre-squeeze and squeeze within programs.
    • Proportional valve driving circuit galvanic insulated.
    • Proportional valve full scale setting (99%) from 5 to 10V.
    • Forging solenoid-valve output.
    • Pre-stroke solenoid -valve.
    • Possible association of pressure in pre-squeeze, squeeze, preheat, welding and forging, through the proportional valve (pressure cycle).
    • Self-calibration of 4 transformer or welding systems.
    • Four language setting, additional languages on request.
    • Dedicated signals management by PLC.
    • IGBT power unit with water or air cooling, through integrated water control solenoid valve or fans.
    • Possibility of external 24V power supply in case of lack of power line.
    • Temperature monitoring of heat sink.
    • External temperature monitoring (transformer diode or coils).
    • Automatic checking and errors reports on Rogowski coil insulated or in short.
    • Check with any reporting / management start welding pliers not closed.
    • Graphs trends of weld parameter on the terminal panel.
    • Automatic duplication of the welding program in multiple programs
