Altivar 71 And Altivar 71 Plus Variable Speed Drives Page 7 Introduction

7 Altivar 71 variable speed drives Introduction Eco-friendly and energy-saving The Altivar 71 drive has been designed to provide significant energy savings in industrial processes, that have un-balanced loads. It has been designed as an eco-friendly product (using 90 % recyclable materials, compliant with environmental standard ISO 14040). It is RoHS-compliant. Compliance with international standards and certifications The entire range conforms to international standards IEC/EN 61800-5-1, IEC/EN 61800-2, IEC/EN 61800-3, is UL 508C, CSA, DNV, C-Tick, NOM 117 and GOST certified, and has been developed to meet the requirements of directives regarding the protection of the environment (RoHS, WEEE, etc.) as well as those of European Directives ( e mark). Functional safety and ATEX applications The Altivar 71 drive features a Power Removal safety function that is designed to help ensure motor stopping and help prevent accidental restarts. This safety function means that the drive can be installed as part of the safety system for an Electrical/Electronic/Programmable Electronic control system relating to the safety of a machine or industrial process. It meets the requirements of category 3 of the ISO 1384 machine safety standard, SIL 2 of IEC/EN 61508 and standard IEC/EN 61800-5-2 which covers the functional safety requirements of power drive products. The Power Removal safety function also enables the Altivar 71 drive to offer protection for motors installed in explosive atmospheres (ATEX certification). Product range (continued) The Altivar 71 AC drive is designed for the control of three-phase asynchronous and synchronous motors in constant-torque applications. It includes an LCD Graphic display keypad with an easy-to-read display and navigation wheel that allows users to scroll through drop-down menus. The Altivar 71 comes standard with: LCD graphic keypad, eight lines of 24 characters Integrated RJ45 port, Modbus, or CAN networks selectable Removable control terminal block with the following I/O: Six logic inputs One power removal input Two analog inputs One analog output Two relay outputs (1NO/NC, 1NO) The Altivar 71 drive integrates the Modbus and CANopen protocols as standard, as well as over 150 functions. These functions can be extended using communication option cards, I/O extension cards, and encoder interface or an Integrated Machine controller card, which allows customer programming in the SoMachine environment. External options such as braking resistors, line and load reactors, and filters complete the offer. Mounting options The Altivar 71 drive can be mounted in a variety of ways for integration in various devices. Wall Mounting The Altivar 71 can be mounted directly on a wall without having to be installed inside an enclosure. UL Type 1 can be achieved using kit VW3A92 pp . Flange-mounting in enclosure The Altivar 71 drive has been designed to optimize the size of enclosures. This type of flange-mounting can be used to reduce the size of enclosure required and to limit the temperature rise inside the enclosure: b The power section, with Type 12/IP 54 degree of protection, can be mounted outside the enclosure using kit VW3A95 pp . This type of mounting can lead to ambient temperatures of up to 60C inside the enclosure without derating. It may be necessary to use a control card fan kit VW3A94 pp appropriate for the drive rating in order to avoid hot spots. Electromagnetic compatibility Observing requirements of electromagnetic compatibility were considered right from the design stage. The incorporation of EMC filters in ATV71H ppp M3 , ATV71 pppp N4 , and ATV71 pppp Y drives and the recognition of EMC requirements facilitates installation and provides economical means of helping ensuring that machines receive the e mark. ATV71H ppp M3X and ATV71H ppp S6X drives have been designed without an EMC filter. Filters are available as an option and can be installed by the customer to reduce the level of emissions.
