COMPAX requires thefollowing data:♦ The parameters of the motor.For Parker ñ standard motors, select the connected motor type from a list; therelevant parameters are stored in the ServoManager.For other motors, the relevant parameters P100-P133 must be set according tothe connected motor (see from Page 91).♦ The parameters of the application.These are mainly the moments of inertia (with and without load) that the drivehas to move, which are set, depending on the drive type, via the parametersP80 ... P92.♦ Dependent on the sensor system, you can select from 2 structure variants; thesealso contain (set via the ServoManager) fixed settings of optimizing parameters.The standard structure corresponds to the previous COMPAX control structure.With the standard structure, you can directly transfer previous, alreadyoptimized parameter sets.♦ After this, the optimal control dynamic is set by increasing the stiffness (P23).This is usually sufficient to obtain good control results.User-defined settings♦ For further optimization, you can adapt the parameters of the set structurevariants optimally to your application (user-defined settings).♦ As another alternative, you can select structure variant 3 and optimize it with therelevant parameters.Optimizing the movement cycle♦ At the end of every optimization of the control accuracy, the movement cyclemust be optimized. For this, use the pre-control parameters P25, P26, P69 andP70.Optimizing with the ServoManager:Use the menu "Online: Parameters" to change the optimizing parametersdirectly in COMPAX (these settings are accepted after modification with"Return").
