The frequency inverters in the ZAdyn model range developed exclusively for elevator technology deliver maximum functionality with minimal dimensions. They conveniently and precisely control the speed of the elevator machine and are suitable for mounting both in control cabinets and on walls with various housings and a compact design.
With the ZAdyn frequency inverter, cable elevators with synchronous or asynchronous motors (also from other manufacturers) offer maximum travel comfort and absolute-precision positioning of the elevator car.
The integrated Safe Torque Off (STO) safety function according to IEC 61800-5-2 (SIL 3) fulfils the requirements of EN 81-20. Evacuation journeys are possible with UPS and batteries. The intuitive software offers monitoring functions in accordance with the Lift Directive 2014/33/EU:
- Direction of travel change counter for lifts with cables or belts featuring a plastic jacket
- Self-monitoring of the motor brake for protecting against unintended car movement
- Self-monitoring of the motor brake as part of the protective device for preventing the car from overspeeding when travelling upwards
