Description of Motion Control Card
The JMC-8134 is a 4 axes motion control card with PCI interface. It can generate high frequency pulses to drive stepping motors and servo motors. Multiple JMC-8134 cards can be used in one system. Incremental encoder interface on all four axes provide the ability to correct for positioning errors generated by inaccurate mechanical transmissions. In addition, mechanical sensor interface, servo motor interface and general purpose I/O signals are provided for system integration.
Figure 1.1 shows the function block diagram of JMC-8134 card. JMC-8134 uses one ASIC to perform 4 axes motion control. The ASIC is made of Nippon Pulse Motor incooperation. The motion control functions include linear and S-curve acceleration/deceleration, interpolation between two axes, continuous motion, in positioning and home return are done by the ASIC. Since these functions needing complex computations are done internally on the ASIC, the PCs CPU is free to supervise and perform other tasks.
Motion Pannel, a Microsoft Windows based software is equipped with the JMC-8134 card for supporting application development. The Motion Creator is very helpful for debugging a motion control system during the design phase of a project. The on-screen monitor shows all installed axis information and I/O signals status of JMC-8134 cards. In addition to Motion Pannel, both DOS and Windows version function library are included for programmers using C++ and Visual Basic language. Several sample programs are given to illustrate how to use the function library.
