600-hp industrial drive module

Feb. 11, 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.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. 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.   ACS850 has an automatic energy optimizer that provides for optimum drive efficiency. An on-board energy saving calculator monitors energy usage and indicates the amount of energy saved in kW hours, dollars, and tons of CO2. This tool also illustrates the duration curve, showing the load profile of the drive. The drive’s internal fan features an automatic on/off control, which provides additional energy savings by switching the cooling fan off when the drive is not active. The same on/off control can control another fan, to cool the cabinet, for example -- saving more energy, and reducing control room noise.
