Motion and access control
The constraints that shaped how we design.
Motion and access control electronics sit at an awkward intersection: a power stage, a safety-relevant decision and a field bus on the same board, in an enclosure nobody opens for years. Most of our work has been here — gate and barrier control units, motor drivers, access management systems.
Motion and access control
The constraints that shaped how we design.
Motion and access control electronics sit at an awkward intersection: a power stage, a safety-relevant decision and a field bus on the same board, in an enclosure nobody opens for years. Most of our work has been here — gate and barrier control units, motor drivers, access management systems.
None of these problems belong to gates. A conveyor drive has the same thermal average, a dosing pump has the same unknown mechanical load, a machine peripheral has the same switching stage next to the same bus transceiver. What changes is the mechanism and the certification path.
- Duty cycle, not peak loadA gate operator's motor stage may run thousands of cycles a week, with stalls that look like normal operation. Sizing for peak current is easy; sizing for the thermal average is where boards fail.
- A load nobody measuredFriction changes with weather, the installer sets the limits, the gate ages. Current sensing and position handling have to tolerate a load the designer never measured.
- Safety-related switchingPhotocells, edge sensors and stop inputs are not features; they are conditions the board has to honour even while its firmware is confused. Such logic belongs in hardware paths independent of software state.
