Three dimensional circular interpolation 4- and 6-axis motion control cards
March 2007
Motion Control & Drives
Each year, the required number of I/O points and axes increases as machinery and manufacturing processes grow in complexity. More advanced interpolation and increased accuracy are also key trends. Advantech's new PCI-1241, PCI-1242 and PCI-1261 motion control cards are designed for all these trends.
2D and 3D interpolation for linear, circular and even arc motion, as well as T-curve and S-curve acceleration is supported, and the maximum pulse output rate is up to 4 Mpps. Blended motion trajectory control and group functions are also available. A special ASIC was designed to provide these powerful functions. The advanced interpolation can accurately form shapes like propellers or small turbines, so it is expected that the new series will be used for very advanced motion control.
For more I/O points, the cards can easily be combined with I/O cards such as the PCI-1756 with 64 isolated digital input and output channels.
One of the most common requirements for motion control solutions is the ability to group axes. The axes of one motion control card can be defined as the ground, and then support two groups with 2D linear or circular interpolation. This is useful for applications such as multiple-axis tooling machines as they need to be synchronised.
Based on P-type closed-loop control, PCI-1241 supports an additional circuit that allows PCI-1241 to drive voltage-type servo motors with -10 to +10 V signals, and permits PCI-1241 to be applied to multi-axis precision servo control.
All three motion control cards provide precise position and rotation control, as each axis is equipped with a 32-bit logical position counter that counts the axis pulse output number and a 32-bit real position counter that records the feedback pulse from the outside encoder or a linear scale.
