functions

Important requirements for a rapid, stable adjustment are the correct information
about the physical characteristic values of the application. COMPAX requires the
following data:

The parameters of the motor.

For Parker – standard motors, select the connected motor type from a list; the
relevant parameters are stored in the ServoManager.
For other motors, the relevant parameters P100-P133 must be set according to
the connected motor (see from Page 91).

The parameters of the application.

These are mainly the moments of inertia (with and without load) that the drive
has to move, which are set, depending on the drive type, via the parameters
P80 ... P92.

Dependent on the sensor system, you can select from 2 structure variants; these

also 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, already
optimized 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 structure

variants optimally to your application (user-defined settings).

As another alternative, you can select structure variant 3 and optimize it with the

relevant parameters.

Optimizing the movement cycle

At the end of every optimization of the control accuracy, the movement cycle

must be optimized. For this, use the pre-control parameters P25, P26, P69 and
P70.

Optimizing with the ServoManager:
Use the menu "Online: Parameters" to change the optimizing parameters
directly in COMPAX (these settings are accepted after modification with
"Return").
