Daikin Industries Minor Lube Controlled Eurocard Driver

It detects the spool position with a differential transformer and optimally controls the KSP valve that performs feedback control (minor feedback). Due to constant current characteristics, there is almost no output current fluctuation due to power supply voltage fluctuations or solenoid temperature rises. The output current waveform (dither frequency, amplitude) is set to maximize the hysteresis and resolution of the proportional solenoid control valve. The current is controlled by PWM (Pulse Width Modulation) method, so heat generation of the driver is kept to a minimum. Equipped with a function (response time adjustment function) that gently changes the output current in response to step-like changes in the command input, it is possible to change the hydraulic output shocklessly (rising and falling respectively). independently adjustable).
