Specification: The ZETADYN 4 is the result of consistent further development of the ZETADYN 3. The housing design and the compact construction makes the ZETADYN 4 perfect for switch cabinet installation as well as for wall installation in the machine room or elevator shaft.
The function Safe Torque Off (STO) enables a contactorless operation of the elevator motor without the disturbing switching noises.
For cable elevators with synchronous or asynchronous motors as well as hydraulic elevators, the ZETADYN 4 guarantees the highest level of travel comfort and the most exact stopping precision.
The software, matched specifically to the elevator technology, facilitates intuitive operation and fast commissioning.
Attributes and special features:
STO (Safe Torque Off) according to IEC 61800-5-2 (SIL 3) for contactorless operation
Electronic short-circuit of the motor windings for safe emergency operation
Integrated line reactor and radio interference filter for highest EMC reliability
Autotune-function for asynchronous motors
Electronic motor name plate for synchronous motors
Certified brake monitoring according to EN81-A3
Multiple interfaces to the elevator controller
Open-loop operation of asynchronous machines
ZETAPAD removable operating module also usable for remote control
