Zadyn4C – Frequency Inverter for Elevator Technology

The ZAdyn4C is a frequency inverter developed exclusively for elevator technology. It enables comfortable and accurate speed control of elevator machines, providing high levels of travel comfort and precise stopping accuracy in cable-operated elevators with synchronous or asynchronous motors. The inverter features an integrated Safe Torque Off (STO) safety function according to IEC 61800-5-2 (SIL 3), fulfilling EN 81-20 requirements. All interfaces for connecting elevator control technology and rotary encoders are already integrated. The ZAdyn4C is suitable for wall mounting in the machine room or elevator shaft and operates without motor contactors, eliminating switching noise.
