Plastics Products: HNC100 Controller The HNC100 is a programmable digital controller with NC capabilities. It handles communication to the higher-level SPS or PC controller, to HNCs, and to sequence control and the closed-loop control from up to two independent drives per unit. Its closed-loop capabilities include: WIN-PED Windows-based software simplifies the parameterizing and sequence programming. Capabilities include: HNC100 controllers support Profibus-DP, Interbus-S, CANopen fieldbuses and the SERCOS interface as a drive bus. Closed-loop position control: PDT1 controller Linear gain characteristic curve Direction-dependent gain Inflected gain characteristic curve (linearization of valve curves) Gain can be changed via the NC program Fine positioning (switching integrator) Residual voltage principle/overlap jump Compensation of valve offset State feedback (Acceleration/pressure) Command value feedforward Limitation of control value via the NC program Position-dependent braking Open-loop controlled startup, closed-loop controlled braking (linear, root-shaped, or sinusoidal characteristics) The same parameters used for the position controller are also used for closed-loop controlled braking Closed-loop velocity control PI controller Closed-loop pressure/force control: PIDT1 controller Differential pressure evaluation for closed-loop force control Pressure limitation Position monitoring Alternating closed-loop control: Closed-loop position control Closed-loop pressure control Synchronization control 2-axis synchronization for each HNC100 Master-slave principle
