Description

ZIEHL-ABEGG Elevator ZAdyn Variable Frequency Drive

With the frequency inverters from the ZAdyn model range, which have been developed exclusively for elevator technology, you can conveniently and precisely control the speed of your elevator machines. These inverters are suitable for mounting either in control cabinets or on walls. In cable-operated elevators with synchronous or asynchronous motors, ZAdyn frequency inverters provide high levels of travel comfort and precise stopping accuracy. The software, specifically tailored to elevator technology, ensures intuitive operation and fast start-up. Additionally, the wide variety of interfaces allows easy connection to the elevator control system.

Features

The integrated Safe Torque Off (STO) safety function according to IEC 61800-5-2 (SIL 3) fulfils the requirements of EN 81-20. As there is no switching noise from the motor contactors, ZAdyn4C and ZAdynpro frequency inverters can also be installed in noise-sensitive areas of buildings.
Evacuation procedures can be performed with an uninterruptible power supply (UPS) of 1~230 VAC and with a battery-based power supply.
The ZAdyn software features monitoring functions in line 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 as an element 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.
