ABB has launched its ACS850 drive module for industrial machinery and applications, such as extruders, cranes, mixers, pumps and fans, in the power range 1.1 to 400 kW, with voltages from 380 to 480 V.
Among its features are an on-board energy-saving calculator that indicates the amount of energy consumed and the amount saved in kW hours, as well as the financial impact of its operation.
The drive’s internal fan has an automatic on/off control that the company said helps save energy by switching the cooling fan off when the drive is not active.
The start-up assistant guides users through the required parameters during the drive start-up process, which helps enable more precise parameter tuning.
The drive also includes an embedded Modbus1 serial link that can be configured as a high-speed drive-to-drive link for master/follower functionality. Other common fieldbuses are supported.
The drive’s maintenance assistant gives an advance warning of maintenance needs of the drive,
motor, or related components.
Direct torque control enables improved performance close to zero speed without an encoder, low motor noise mode, higher output frequency, and improved motor identification at stand still.
The drive modules are compact, with protection class IP20, and designed for installation into
cabinets.
The smallest module width is 90 mm. The modules can be installed side-by-side, with cable terminals located in such a place that enables cabinet assembly.
