Differen ramp mode can be se: - single ramp for any reference variaion - wo ramps for increasing and for decreasing reference variaions - four ramps for posiive/negaive signal values and increasing/decreasing reference variaions Ramp generaor is useful for applicaion where smooh hydraulic acuaion is necessary o avoid machine vibraion and shocks. If he proporional valve is driven by a closed loop driver, he ramps can lead o unsable behaviour, for hese applicaions ramp funcion can be sofware disabled (defaul seing) inearizaion inearizaion funcion allows o se he relaion beween he reference inpu signal and he conrolled valve s regulaion. inearizaion is useful for applicaions where i is required o linearize he valve s regulaion in a defined working condiion Diher he diher is an high frequency modulaion added o he valve s reference signal o reduce he hyseresis of he valve s regulaion; in fac a small vibraion in he valve s hydraulic regulaion considerably reduces he mechanical fricion effecs (e.g. due o cylinder seals).
