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 unique motor-control platform, Direct Torque Control (DTC).
These industrial drive modules are designed for industrial machinery and applications such as extruders, cranes, mixers, web handling and converting, in the power range of 1.5 to 600hp at 480VAC.
An integrated Safe Torque Off (STO) feature removes the torque from the motor shaft. This safety feature conforms to the requirements of SIL 3 / IEC 61508, Cat 4/EN 954-1, EN ISO 13849-1:PL e. There are also solutions available for Safe Stop 1(SS1), Safe Limited Speed (SLS), Safe Brake Control (SBC), Safe Speed Monitor (SSM) and Safe Direction (SDI).
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
The intelligent user interface with advanced assistants significantly decreases the need to refer to manuals, while saving time in commissioning.
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.
The maintenance and diagnostics assistants help keep the process up and running and, in cases of disturbance, minimize the downtime by giving advance warning of maintenance needs of the drive, motor or related components.
These compact drive modules, with protection class IP20 (G frame IP00), are optimized for installation into cabinets. The smallest module width is only 3.7in. The modules can be installed side-by-side, which saves space as more drives can be placed in the same cabinet.
