PCI-1756

64-ch Isolated Digital I/O Card

Solution Description

Bending machines function by taking advantage of

separate motors to create differential torque. A tube

traveling through the motors will be bent due to this

opposing force. Sensors will then perform quality

checks on the bent tube to ensure proper shape and

smoothness. For a voltage type driver controlling

motor speed and torque, Advantech’s PCI-1241 uses

an ASIC with a DDA (Digital Differential Analyzer) for

4-axis servo positioning and synchronizing controls

in order to evenly move the axis. Furthermore, the

closed-loop control is implemented with P control,

and -10 to +10V signals are used for outputs to the

servo motor driver. With PCI-1241’s 128 isolated

digital input and outputs, functional expansions are

made possible.

Before any bendling can be implemented, the sensor

needs to detect the metal tube for length control.

Furthermore, it ensures the perfect shape for the

metal tube avoiding the unexpected operation. With

Advantech’s PCI-1756, a variety of sensors can be

implemented. It allows a large data flow between

stations, and more external controls are enabled.

Conclusion

In order to operate such a delicate job, using voltage command motion control cards from Advantech

is the optimal solution. The high bit control and data acquisition rates ensure quality and preciseness of

the tube.
