3.2 Brief description

The PA8000 EL is an open architecture CNC control unit providing

numerical interface for the PA-SDI drive. This control unit can be

extended via a superbus interface and external input/output mod-

ules (PAMIO) to connect a wide range of machine tools.

Depending on the model, the PA8000 EL provides one or two

internal input/output modules. Thus it is able to control either 24

inputs and 16 outputs, or 48 inputs and 32 outputs.

Machine tool axes are controlled by digital drives of the PA-SDI

range. These drive units are connected via a single digital bus

daisy-chained from the control to the drives. The number of drives

(and thus of axes) depends on the software options. The drives

also ensure the input of various measurement systems, either

incremental or absolute, depending on the velocity of the motors or

the position control loop of the CNC.

Via its Superbus extension board (always included) it is possible to

connect PA modular input/output modules (PAMIO) to extend the

capacity of digital inputs/outputs and/or analog inputs/outputs.
