6 MAIN SOFTWARE PARAMETER SETTINGS The following is a brief descripion of he main seings and feaures of E-MI-AS drivers. For a deailed descripions of all available seings, wirings and insallaion procedures, please refer o he programming manuals E-MAN-MI-AS included in he E-SW-PS Dvd (see secion 5) 6.1, 6.2 - Scale, Bias & Threshold curren Scale Bias Solenoid regulaion 6.1 Scale Scale funcion allows o se he maximum curren supplied o he solenoid, corresponding o he max valve regulaion, a maximum reference signal value. This regulaion allows o adap he maximum curren supplied from he driver o he specific nominal curren of he proporional valves o which he driver is coupled; i is also usefull o reduce he maximum valve regulaion in fron of maximum reference signal. Threshold Bias reference 6.2 Bias and Threshold Proporional valves may be provided wih a dead band in he hydraulic regulaion corresponding o heir swich-off saus. This dead band disconinuiy in he valve s regulaion can be compensaed by acivaing he Bias funcion, which adds a fixed prese Bias value o he reference signal (exernal inpu or inernally generaed). The Bias funcion is acivaed when he reference signal overcome he Threshold value, prese ino he driver. The Bias seing allows o calibrae he Bias curren supplied o he solenoid of he specific proporional valve o which he driver is coupled. The Threshold seing is useful o avoid undesired valve regulaion a zero reference signal when elecric noise is presen on he analog inpu signal: smaller hreshold reduces he reference signal dead band, greaer values are less affeced by elecric noise presence. If inernal reference generaion is acive (see 6.6), hreshold should be se o 0. 6.3 - Ramps reference curren 6.3 Ramps The ramp generaor allows o conver sudden change of elecronic reference signal ino smooh ime-dependen increasing/decreasing of he curren supplied o he solenoid. Differen ramp mode can be se: - single ramp for any reference variaion - wo ramps for increasing and for 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 conroller, he ramps can lead o unsable behaviour, for hese applicaions ramp funcion can be sofware disabled (defaul seing) 6.4 - Diher reference curren 6.4 Diher The diher is an high frequency modulaion of he curren supplied o he solenoid, o reduce he hyseresis of he valve s regulaion: a small vibraion in he valve s regulaing pars considerably reduces saic fricion effecs. Diher frequency can be se in a range from 80 o 500 Hz (defaul value is 200Hz). Lower diher seing reduces he hyseresis bu also reduces he regulaion sabiliy. In some applicaion his can lead o vibraion and noise: righ seing usually depends on sysem seup. Defaul diher is a valid seing for a wide range of hydraulic applicaions 6.5 - Linearizaion curren Scale 6.5 Linearizaion Linearizaion funcion allows o se he relaion beween he reference inpu signal and he curren supplied o he solenoid. Linearizaion is useful for applicaions where i is required o linearize he valve s regulaion in a defined working condiion (e.g. maximum pressure conrol a defined working flow) Bias 6.6 Inernal Reference Generaion Inernal generaion of reference values is sofware selecable. In his mode he 2 driver inpus (see 4.6) allow o selec he desired solenoid curren reference signal, among he differen inernal sored values: exernal conrol uni can hus manage complex machine profile by simple swiching of he reference signal, by 2 digial inpus (see 4.6). Each digial inpu combinaion corresponds o a differen reference value; up o 4 differen inernal values are available: Inernal generaed references REF1 REF2 REF3 REF4 CMD1 0 24 VDC 24 VDC 0 6.6 - Inernal Reference Generaion reference reference CMD2 0 0 24 VDC 24 VDC A differen ramp ime value can be se by sofware for each available sored reference value. 6.7 Hydraulic Power Limiaion (opion /W) E-MI-AS drivers wih /W opion elecronically perform hydraulic power limiaion on single solenoid valves: - flow conrol valves (direc and pilo operaed) - direcional conrol valves (direc and pilo operaed) + mechanical pressure compensaor - variable displacemen pumps wih proporional flow regulaor (e.g. PVPC-*-LQZ, ab. A170 ) The driver receives he flow reference signal by he analog exernal inpu CMD1 (see 4.2) and a pressure ransducer, insalled in he hydraulic sysem, has o be conneced o he driver s analog inpu CMD2 (see 4.3). When he acual requesed hydraulic power pxq (CMD2xCMD1) reaches he max power limi (p1xq1), inernally se by sofware, he driver auomaically reduces he flow regulaion of he valve. The higher is he pressure ransducer feedback he lower is he valve s regulaed flow: PowerLimi [sw seing] Flow regulaion = Min ( ; Flow Reference [CMD1]) Transducer Pressure [CMD2] CMD2 CMD1 6.7 - Hydraulic Power Limiaion Q Q1 reference signal for valve regulaion p1 Regulaion curve wih and wihou power limiaion. p1 x Q1 = max power limi pressure feedback p G020

6 MAIN SOFTWARE PARAMETER SETTINGS The following is a brief descripion of he main seings and feaures of E-BM-AS drivers. For a deailed descripions of all available seings, wirings and insallaion procedures, please refer o he programming manual E-MAN-BM-AS included in he E-SW-PS Dvd programming sofware(see secion 5) 6.1 Scale Scale funcion allows o se he maximum curren supplied o he solenoid, corresponding o he max valve regulaion, a maximum reference signal value. This regulaion allows o adap he maximum curren supplied from he driver o he specific nominal curren of he proporional valves o which he driver is coupled; i is also useful o reduce he maximum valve regulaion in fron of maximum reference signal. For double solenoid valves wo differen Scale regulaions are available : ScaleA for posiive reference signal and ScaleB for negaive reference signal 6.2 Bias and Threshold Proporional valves may be provided wih a dead band in he hydraulic regulaion corresponding o heir swich-off saus. This dead band disconinuiy in he valve s regulaion can be compensaed by acivaing he Bias funcion, which adds a fixed prese Bias value o he reference signal (exernal inpu or inernally generaed). The Bias funcion is acivaed when he reference signal overcome he Threshold value, prese ino he driver. The Bias seing allows o calibrae he Bias curren supplied o he solenoid of he specific proporional valve o which he driver is coupled. The Threshold seing is useful o avoid undesired valve regulaion a zero reference signal when elecric noise is presen on he analog inpu signal: smaller hreshold reduces he reference signal dead band, greaer values are less affeced by elecric noise presence. If inernal reference generaion is acive (see 6.6), hreshold should be se o 0. For double solenoid valves wo differen Bias regulaions are available: posiive reference signal acivaes BiasA for solenoid S1 and negaive reference signal acivaes BiasB for solenoid S2 6.3 Ramps The ramp generaor allows o conver sudden change of elecronic reference signal ino smooh ime-dependen increasing/decreasing of he curren supplied o he solenoid. 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 conroller, he ramps can lead o unsable behaviour, for hese applicaions ramp funcion can be sofware disabled (defaul seing) 6.4 Diher The diher is an high frequency modulaion of he curren supplied o he solenoid, o reduce he hyseresis of he valve s regulaion: a small vibraion in he valve s regulaing pars considerably reduces saic fricion effecs. Diher frequency can be se in a range from 80 o 500 Hz (defaul value is 200Hz). Lower diher seing reduces he hyseresis bu also reduces he regulaion sabiliy. In some applicaion his can lead o vibraion and noise: righ seing usually depends on sysem seup. Defaul diher is a valid seing for a wide range of hydraulic applicaions 6.5 Linearizaion Linearizaion funcion allows o se he relaion beween he reference inpu signal and he curren supplied o he solenoid. Linearizaion is useful for applicaions where i is required o linearize he valve s regulaion in a defined working condiion (e.g. maximum pressure conrol a defined working flow) 6.6 Inernal Reference Generaion Inernal generaion of reference values is sofware selecable. In his mode he 4 digial inpus of he driver (DI1..DI4) allow o acivae he desired inernal reference signal, among he differen driver s sored values: exernal conrol uni can hus manage complex machine profile by simple swiching he reference signal, by 4 digial inpus (see 4.7). The digial inpus are sofware configurable ino 2 differen reference selecion mode: Sandard mode each digial inpu corresponds o a differen value; up o 4 differen inernal values are available (2+2 wih E-BM-AS-PS-05H driving wo single solenoid valves) Binary mode each digial inpu combinaion corresponds o a differen value; up o 15 differen inernal values are available (3+3 wih E-BM-AS-PS-05H when driving wo single solenoid valves) A dedicaed ramp ime value can be se by sofware for each available sored reference value. Noe: wih all inpu signals (DI) se o zero, he driver can be commanded by exernal analog reference also if inernal reference generaion is seleced (for more informaion please refer o he programming manual E-MAN-BM-AS). 6.7 Hydraulic Power Limiaion (/W opion, only for drivers E-BM-AS-PS-05H) E-BM-AS drivers wih /W opion elecronically perform hydraulic power limiaion on: - direc and pilo operaed flow conrol valves - direc and pilo operaed direcional conrol valves + mechanical pressure compensaor - variable displacemen pumps wih proporional flow regulaor (e.g. PVPC-*-LQZ, ech.ab. A170 ) The driver receives he flow reference signal by he analog exernal inpu CMD1 (see 4.2) or by he inernal generaor (see 6.6), and a pressure ransducer, insalled in he hydraulic sysem, has o be conneced o he driver s analog inpu CMD2. When he acual requesed hydraulic power pxq (CMD2xCMD1) reaches he max power limi (p1xq1), inernally se by sofware, he driver auomaically reduces he flow regulaion of he valve. The higher is he pressure feedback he lower is he valve s regulaed flow: Flow regulaion = Min ( PowerLimi [sw seing] Transducer Pressure [CMD2] ; Flow Reference [CMD1]) 6.1, 6.2 - Scale, Bias & Threshold curren Solenoid S1 regulaion Scale A Bias A Threshold Solenoid S2 regulaion 6.3 - Ramps reference 6.5 - Linearizaion curren DI4 DI3 DI2 DI1 curren 6.4 - Diher Solenoid S2 reference curren Bias B Bias B Bias A Scale B Bias A Bias B 6.6 - Inernal Reference Generaion reference Q Q1 reference signal for valve regulaion Scale B p1 reference Scale A reference pressure feedback Solenoid S1 Single inernal generaor selecion (sandard mode) DI1 DI2 DI3 DI4 Reference OFF OFF OFF OFF Exernal ON OFF OFF OFF Generaion 1 (*) ON OFF OFF Generaion 2 (*) (*) ON OFF Generaion 3 (*) (*) (*) ON Generaion 4 Double inernal generaor selecion (sandard mode) DI1 DI2 S1 DI3 DI4 S2 OFF OFF Exernal OFF OFF Exernal ON OFF Generaion 1 ON OFF Generaion 1 (*) ON Generaion 2 (*) ON Generaion 2 (*) Noe: Don care 6.7 - Hydraulic Power Limiaion Regulaion curve wih and wihou power limiaion. p1 x Q1 = max power limi p G030
