PCI Bus, High Speed 4 Axis Motion Control Board


PCI Bus, High Speed 4 Axis Motion Control Board

    Item Not Available  


The PISO-PS400U has officially been phased out and will no longer be available. It has now been replaced by PISO-PS400U

PISOPS400The PISO-PS400 is a 4-axis stepping/pulse-type servo motor control card that can be used on any IPC with 5V PCI bus, and is suitable for general-purpose motion applications. This card also contains one port of FRnet which allows IPC to expand its fast remote I/O easily. This two-wired FRnet can have maximum 128 DI and 128 DO, and they are automatically scanned with a period of 2.88 ms. PISO-PS400 contains a high-performance motion ASIC. Apart from a wide speed range, this intelligent motion controller also has a variety of motion control functions built in, such as 2/3- axis linear interpolation, 2-axis circular interpolation, T/S-curve acceleration/deceleration, various synchronous actions, automatic homing, and others. In addition, most of the PISO-PS400 motion control functions are performed with little load on the processor. The motion status, FRnet I/O, and the other I/O cards on IPC can still be monitored while driving. As a result of the low CPU loading requirements of the PISO-PS400, one or more motion cards can be used on a single IPC. ICPDAS has also provided a variety of functions and examples to reduce the need for programming by users, making it a highly cost-effective solution for motion builders.
