Features
This 4-axis position-control module has these features:
• Open-loop or closed-loop control
• Independent and coordinated axis control
• Position- and time-based control
• Accumulator push-out control
• Zero-scale/full-scale (offset & span) calibration for position inputs
• PID with anti-windup, bumpless parameter changes, setpoint weighting, and
limited high-frequency derivative gain.
• Profile interpolation (linear or cubic spline) between setpoints
• Converging/diverging tooling (direct/reverse acting control)
• Three hold values per axis: manual position, purge, or die gap
• Independent profile scale and offset adjustments
• Automatic parison weight adjustment
• Setpoint marking
