Chip-level controllers run spiral (helical) interpolation: Nippon Pulse PCL6000 series

Nippon Pulse’s PCL6000 series of chip-level controllers include the two-axis PCL6025B and the four-axis PCL6045BL and PCL6046 chips. Their advanced features have long made them the most advanced controller chips in the world. In addition to standard linear and circular interpolation options, two of the advanced controller chips now feature a third interpolation option — spiral or helical interpolation.

The PCL6045BL and PCL6046 four-axis chips can both execute spiral interpolation. For this type of movement, linear and circular motion profiles are used simultaneously, combining to create three dimensions of movement. The zero point keeps moving, and the X and Y axes synchronize with the Z axis for either clockwise or counter-clockwise helical motion.

Spiral interpolation can be used in conjunction with acceleration and deceleration as well … by entering the number of pulses required in the register for control axis. For more information about this feature and how to perform these operations, check out section 9.8.9 in either chip’s user manual: PCL6045BL and PCL6046 on the Nippon Pulse Manuals and Literature page.
