PERFORMANCE Motion Devices (PMD), a pioneer in the development of chip-based motion control, has announced its new multi-chip, multi-axis synchronisation capability for the Navigator and Pilot motion processors.
PMD's Navigator chipset controls up to four axes of brushed dc servos, brushless dc servos, steppers, and microsteppers; the Pilot is a low cost, single axis control for the same type of motors.
This new multi-chip synchronisation capability allows more than four axes of motion to be coordinated between the Navigator and Pilot chips, or any combination of them.
This feature also enables physically remote or distributed chips to be synchronised to within microseconds so they can be used for coordinated motion.
With this capability, PMD is essentially synchronising the internal cycle of the chips. The time breakpoint mechanism is then used to start or stop events (motion) based on this globally distributed and synchronized time.
The synchronisation feature is implemented by one signal that is distributed across several PMD motion chips; one chip acts as the master and the rest act as slaves.
Once motion has begun, it remains coordinated because each chip's internal cycle of calculation is synchronised with the master chip.
The synchronised mode of operation can be turned on or off via chip commands. This feature is software backward compatible with existing Navigator and Pilot chips, so existing designs can be enhanced to support this feature.
PMD's motion processors excel in applications where fast, smooth, synchronised motion is a requirement.
These applications include medical equipment, materials handling, semiconductor manufacturing, and industrial automation and robotics. Motion Solutions Australia 03 9563 0115.
