Why Use This System?

Because you can interact quickly and easily with the module’s control of

axis motion via the Hydraulic Configurator, this control system has

these benefits:

• faster setup and tuning of axes – the Hydraulic Configurator lets you

quickly set up and tune each axis independent of your ladder program.

• reduced cycle time – you can increase axis speed for faster operation

• smoother operation for longer machine life – you can profile accelerations

and decelerations of the hydraulic actuator to limit pressure spikes

• faster change-over to new parts – you can store setups (configuration

parameters) for quick an accurate change-over between parts

The module compares ACTUAL POSITION with TARGET POSITION to

determine position error. Every update, it uses the position error to adjust

drive output. PID gains are adjustable and can be applied selectively.

The module also provides two different feedforward algorithms;

EXTEND/RETRACT FEEDFORWARD, and EXTEND/RETRACT

ACCELERATION FEEDFORWARD. These feedforward terms provide

additional drive output to help the axis follow the target, freeing the

PID loop to correct for system nonlinearity and changes in load.
