2010-02-03 - New ACS850 provides industry, OEMs, with a compact package that greatly simplifies installation and use. Drive has embedded Safe-Torque-Off SIL3
New Berlin, Wisconsin, February 5, 2010 – ABB’s new drive module ACS850 is now available and UL listed up to 600 HP.
The ACS850 features on-board safe-torque-off, a removable memory block, intelligent user interface with a series of assistant wizards, a built-in energy saving calculator, and modular hardware and software. It also includes an advanced adaptation of ABB’s exclusive high-performance motor-control platform, Direct Torque Control (DTC).
The ABB industrial drive modules are designed for industrial machinery and applications such as extruders, cranes, mixers, web handling and converting, in the power range 1.5 to 600 hp at 480 Vac. “The drive is targeted specifically at OEMs, panel builders and system integrators,” said Thomas Junger, product manager for the ACS850. “The 10 hp drive is only 4 inches wide. The sheer quantity of drives you can fit into a cabinet is going to make the ACS850 a popular product.”
Integrated safety
Safety as standard is provided by an integrated Safe Torque Off (STO) feature, which removes the torque from the motor shaft. This safety feature conforms with the requirements of SIL 3 / IEC 61508, Cat 4/EN 954-1, EN ISO 13849-1:PL e. There also are solutions available for Safe Stop 1(SS1), Safe Limited Speed (SLS), Safe Brake Control (SBC), Safe Speed Monitor (SSM) and Safe Direction (SDI).
Removable memory block
A removable memory block increases the flexibility of the drive and provides for easy maintenance. The memory block stores the complete firmware, plus all user settings and motor data. If the drive is replaced, it can be re-commissioned without any special knowledge via simply plugging the memory block into the new drive.
Moreover, the memory block allows the application software and parameter configuration changes to be made at an OEM’s own assembly plant before being sent to the end-user site, just-in-time for commissioning the drive.
Intelligent user interface
The intelligent user interface with advanced assistants significantly decreases the need to refer to manuals, while saving time in commissioning:
-- Macros, predefined parameter settings for specific applications, provide for a faster startup. The settings can easily be modified, if required, to customize to your application;
-- The startup assistant guides the user through the needed parameters during the drive startup process allowing for trouble-free and fast commissioning; and
-- Several other features like short/long parameter menus, I/O mapping, and list of latest parameter changes make the use of the drive easier.
The ACS850 is engineered to work with the latest generation of ABB high-speed serial interface modules. Supported protocols include DeviceNet, Modbus RTU, Profibus, and CANopen. Before the end of 2009, the ACS850 also will support Ethernet/IP and Modbus-TCP.
