Parker Hannifin S.p.A. - Divisione S.B.C. LVD User’s Manual253 PARAMETERS AND PROGRAMMINGThe functions of torque, speed, acceleration and position control are performed by a digitalelectronic system. This chapter describes how to enter the data, the meaning of eachprogramming parameter, the functional block diagram and the relative description ofadvanced level functions. When designing the system attention was paid to promoting themaximum ease of use without detracting from the flexibility of the drive.The following figure shows the general block diagram of the parametrisable section of thedrive.The Block diagrams chapter contains a more detailed description of the general block diagramand the block diagrams illustrating specific functions (operating modes). The chapter Pico-PLC describes how to associate inputs/outputs with the parametric functions of the drive.Parameters can be divided on the basis of their functions, as follows:REFERENCECONTROLLIMIT SWITCH&STOPSPEED CON-TROL LOOPOPERATINGMODETORQUELIMITSMANAGEMENTTORQUEanalogdigitalinternalSPEEDWINDOWSTORQUECONTROLACCEL.CONTROLWIRINGTESTPOSITIONCONTROLDIGITALLOCKSTEPPERMOTORSPINDLEORIENT.CANALARMSMANAGEMENTb40.2Pr31DEMANDCAMfrom Pr0 to Pr49 basic parametersfrom Pr50 to Pr70 operating mode parametersfrom Pr71 to Pr99 pico-PLC parametersfrom In0 to In127 pico-PLC instructions
