For Setup and
Troubleshooting
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 acceler-
ations 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
Monitoring Axis Position
The module has four LDT inputs. You configure each axis for an LDT
with a Pulse Width Modulated output (DPM) or a Start/Stop output
(RPM) by changing axis configuration parameters.
Controlling Axis Output
The module is a targeting controller: every two milliseconds its micro-
processor updates
TARGET POSITION and target SPEED values. For
point-to-point moves, TARGET POSITIONS are generated so that
resulting speed, accelerations, and decelerations follow either a
trapezoidal or s-curve profile.
