GM-400 is a low cost and easy to use motion control card that installs directly into the ISA slot. Its compact and powerful design makes it ideally suitable for PC-based applications such as machine tool control, packaging and factory automation.
The heart of the GM-400 is its PMD 1401A DSP motion chipset. The chipset handles the servo algorithms with PID and velocity filtering for all four axes. It performs the intensive computational tasks required for high performance applications such as digital velocity, torque and position control. The dedicated DSP frees the host CPU for other tasks and protects motion control activities from host software concilicts.
For synchronizationwith outside events, GM-400 provides uncommitted I/O, including 8 optoisolated digital inputs and 8 digital outputs. Dedicated optoisolated inputs are provided for Positive/Negative Limits, Home, Drive Alarm and Drive Enable/Reset.
Supplied with a set of plain motion commands and demonstration software, GM-400 is easy to use, by even a novice user. Additional software is available to autotune, view trajectories on a PC screen, translate CAD files into motion and create powerful, application-specific operator interfaces with Visual C.
