PMD motion processors offer multichip synchronization

The Navigator and Pilot motion processors now feature multichip synchronization capability that allows more than four axes of motion to be coordinated between the chips. This feature also enables physically remote or distributed chips to be synchronized to within microseconds for coordinated motion.

The Navigator chip controls up to four axes of brushed and brushless dc servo motors, steppers, and microsteppers. The Pilot chip is a low-cost, single-chip, single-axis version.

The synchronization feature is implemented through a signal that is distributed across several motion chips; one chip acts as the master and the rest act as slaves. Once motion has begun, it will remain coordinated because each chip's internal cycle of calculation is synchronized with the master chip. The synchronized mode of operation can be turned on or off via chip commands.

This feature is software backward-compatible with existing Navigator and Pilot chips, enabling existing to be enhanced to support this feature.

The Navigator and Pilot chips are priced at $114 and $28, respectively, in OEM quantities.
