What types of control sequences does Kalamatasoftware develop?

We build logic sequences for high-pressure automated hydraulic forging presses and stamping machinery. This includes pre-fill, fast approach, pressing, dwell, decompress, and retract cycles, each with configurable pressure and position thresholds.

How does the PID tuning loop work for forging presses?

Our PID Tuning Suite analyzes real-time pressure and position feedback from the press. It calculates optimal proportional, integral, and derivative gains using both open-loop and closed-loop methods. The system simulates step responses so engineers can adjust parameters without stopping production, reducing manual calibration time by up to 60%.

What safety interlocking systems do you provide?

We supply programmable safety interlock controllers that handle emergency stops, light curtain integration, and two-hand control monitoring. They comply with ISO 13849-1 PL d standards and use dual-channel architecture with cross-monitoring to prevent die closure when operators are in the danger zone.

Can your logic sequences integrate with existing PLC environments?

Yes. Our Sequence Logic Engine supports OPC UA for integration with Siemens, Rockwell, and other major PLC platforms. It handles up to 32 concurrent sequences and manages timing dependencies, pressure thresholds, and position interlocks automatically.

Do you offer support for retrofitting older presses?

Absolutely. We design control algorithms that can be deployed on retrofit controllers. Our team works with your existing hydraulic and electrical schematics to map new logic sequences onto legacy hardware, minimizing downtime during the upgrade.

How do you validate safety interlock performance?

Each interlock sequence is tested against fault injection scenarios — simulated sensor failures, communication drops, and operator errors. Diagnostic logs capture all safety events for audit trails, and we provide documentation for ISO 13849-1 compliance verification.

Why control engineers choose Kalamatasoftware

Our logic sequences and PID loops are built for the specific dynamics of high-pressure forging and stamping — not adapted from general-purpose automation.

PID tuning that accounts for press frame elasticity Standard PID controllers ignore structural compliance. Our suite models the press frame as a spring-mass system, so gain calculations prevent oscillation during rapid decompression.

Safety interlock logic with dual-channel cross-monitoring Most safety relays stop at single-channel monitoring. Our controller compares two independent sensor paths on every cycle and locks the press if a discrepancy exceeds 5 ms.

Sequence engine that handles 32 concurrent forging cycles Off-the-shelf PLC sequencers typically manage 8–12 steps. Our engine supports 32 concurrent sequences with per-block pressure thresholds and position interlocks — no ladder-logic workarounds.
