Setting up Compax3 C3F_T40100 192-121102 N04 June 2008Before the activation, please notice the following: Correct connection of the pressure sensors to the controller. By approaching the end limits and simultaneously monitoring the pressurevalues (Status values Æ pressure of main or auxiliary axis Æ pa, pb, pT and p0)it is possible to conclude if the pressure sensors are correctly assigned.A = yclinder at limit AB = cylinder at limit B1 = valve position The pressure signals should be well filtered (smooth). (Optimization Æ Analoginput Æ InX Filter)If those conditions are fulfilled, the pressure compensation can be activated under(OptimizationÆ Output Chain Æ PressureCompensation).b) characteristics compensationThe control behavior of valves with bent characteristic lines or overlap can beconsiderably improved if the valve characteristics are stored in the controller andare used for the compensation. The characteristic is integrated into the resepectivevalve data via the C3HydraulicsManager and is loaded into the controller via theC3ServoManager. The activation of the characteristic line is made via optimizationÆ Output Chain Æ Characterisitic Flow.If the valve characteristic line is activated, the behavior between control signal andspeed should be mainly linear.(Doubling of the setpoint speed Æ Doubling of the resulting speed in the opencontrol loop).c) Deadband compensationIf for valves with overlap or gap no adequate characteristics are available, they canbe optimized with the aid of the deadband compensation. The correspondingvalues are set in (Optimization Æ Output Chain Æ Deadband ...).Autoryzowany dystrybutor Parker:53- 012 Wrocławul.
