The frequency inverters of the ZAdyn series, developed for elevator technology, deliver comprehensive functionality within compact dimensions. They regulate the rotational speed of the elevator motor and, with various housing variants and a compact design, are suitable for both control cabinet and wall mounting.
Rope elevators equipped with synchronous or asynchronous motors (including those from other manufacturers) achieve high ride comfort and extremely precise elevator car positioning when combined with the frequency inverter ZAdyn.
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
