Cabinet frequency inverter ZAdyn series

integratedwall-mountfor asynchronous motors

Overview
With the frequency inverters from the ZAdyn model range, developed exclusively for elevator technology, you can accurately and comfortably control the speed of elevator drives. The compact, varied housing designs support both control-cabinet installation and wall mounting in the machine room or elevator shaft. ZAdyn inverters deliver high travel comfort and precise stopping accuracy for cable-operated elevators with synchronous or asynchronous motors. Software tailored to elevator applications enables intuitive operation and rapid commissioning. A broad selection of interfaces simplifies integration with elevator control systems.

Properties & special features

• Specifically developed for elevator applications to ensure high ride comfort and precise leveling accuracy.
• Drives synchronous and asynchronous motors across a wide power range (4.6 kW to 110.0 kW).
• Compact housing variants suitable for control-cabinet or wall mounting in machine rooms or shafts.
• Elevator-optimised software for intuitive operation and fast start-up.
• Multiple integrated interfaces for simple connection to elevator controls (programmable I/Os, DCP, CANopen-LIFT).
• Integrated Safe Torque Off (STO) safety function according to IEC 61800-5-2 (SIL 3), meeting EN 81-20 requirements.
• Integrated line filters and line reactors matched to elevator-specific EMC standards EN 12015 and EN 12016.
• Integrated short-circuit protection for motor windings (model dependent).
• Stand-by mode via digital input reduces energy consumption by up to 75%.

Ordering, storage, start-up
All interfaces required for connecting the elevator control system and rotary encoders are integrated in the ZAdyn, eliminating the need for optional interface cards during ordering. The external ZApad operating terminal provides a clear, simple menu structure for intuitive operation and straightforward commissioning.

Safety & Noise
The integrated STO function prevents switching noise from motor contactors, allowing installation even in noise-sensitive building areas. The STO implementation complies with relevant elevator safety standards.

Monitoring functions (Lift Directive 2014/33/EU)

• Direction-of-travel-change counter for lifts with ropes or belts featuring plastic jackets.
• Self-monitoring of the motor brake as an element protecting against unintended car movement.
• Self-monitoring of the motor brake as part of the protective device preventing overspeed when travelling upwards.

Evacuation / Power supply
Evacuation can be performed with an uninterruptible power supply (UPS) 1~230 VAC or battery-based power supplies. Important data can be stored in the motor's absolute encoder when used with synchronous motors for backup purposes.

Energy recovery / Efficiency
Stand-by mode reduces energy consumption by up to 75%. For high-usage systems, ZArec4C power recuperation units allow energy to be fed back into the supply during regenerative operation.

EMC
Line filters and line reactors matched to elevator requirements meet EN 12015 and EN 12016 EMC standards.
