1 General notesCompliance with the following instructions is mandatory to ensure the functionality and safety of theproduct. If the following instructions given especially but not limited for general safety, transport,storage, mounting, operating conditions, start-up, maintenance, repair, cleaning and disposal / recy-cling are not observed, the product may not operate safely and may cause a hazard to the life andlimb of users and third parties.Deviations from the following requirements may therefore lead both to the loss of the statutory materialdefect liability rights and to the liability of the buyer for the product that has become unsafe due to thedeviation from the specifications.1.1 ValidityThis instruction manual applies to:Frequency inverter from the series: ZAdyn4CA HYfrom software version 4.531.2 Structure of the operating instructionsThese operating instructions are intended to be a short guide with additional information. Theyare only valid in conjunction with the following operating instructions:• R-TBA12_01 (ZAdyn4C)Before installation and start-up, read this manual carefully to ensure correct use!1.3 Exclusion of liabilityConcurrence between the contents of these operating instructions and the described hardware andsoftware in the device has been examined.It is still possible that non-compliances exist; no guarantee is assumed for complete conformity. Thecontents of this manual are put through periodic reviews. Necessary modifications are incorporatedinto the next version.ZIEHL-ABEGG SE is not liable for damage due to misuse, incorrect use, improper use or as aconsequence of unauthorized repairs or modifications.2 Safety instructionsTheSafety informations,described in chapter 2 of theoperating instructions R-TBA12_01 has to befollowed!3 Product overview3.1 ApplicationThe ZAdyn4CA HY is a field-orientated Frequency inverter for speed control of three-phase asynchro-nous motors in hydraulic lift systems.The ZAdyn4CA HY is designed for the modernisation of existing hydraulic systems.The ZAdyn4CA HY is equipped with a microprocessor control. The use of IGBT modules and pulsewidth modulation with variable switching frequency enables low-noise operation of the motor. Theuser interface, interfaces and software adapted specially to lift technology enable easy installation andstart-up of the machine.3.2 Functional descriptionThe device was designed to modernise hydraulic systems. The soft starter is replaced by theZAdyn4CA HY. Thus, the ZAdyn4CA HY is only used for lifting. Lowering is still done by means of thelowering valve of the valve block. The ZAdyn4CA HY is connected to the elevator control system viaDCP4. For this purpose, the elevator control system must possess a shaft copying encoder. For liftingoperations, the elevator control system gives the ZAdyn4CA HY a travel command with target positionvia DCP4 and at the same time completely opens all open valves on the valve block up to the end oftravel. The travel curve is completely controlled via the ZAdyn4CA HY. A brake resistor is notnecessary.Quick Start Guide ZAdyn4CA HY General notesR-TBA16_01-GB 1845 Index 003 Part.-No. 00163456-GB4/28
