Drives

The ACS850 drive features an in-built, energy-saving calculator, embedded Modbus and drive-to-drive link, intelligent user interface with a series of assistant wizards, integrated safety functions, modular hardware and software, and a removable memory unit.

The ACS850 industrial drive modules are designed 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.

These compact drive modules, with protection class IP20, are optimised for installation into cabinets. The smallest module width is only 90 mm, and the modules can be installed side by side to save space in cabinets.

An onboard energy-saving calculator indicates the amount of energy consumed and the amount saved in kWh as well as the financial impact.

The drive includes an embedded Modbus serial link that can also be configured as a high-speed, drive-to-drive link for master/follower functionality. Other common fieldbuses are also supported.

Safety 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. Other available safety solutions include Safe Stop 1 (SS1), Safe Limited Speed (SLS), Safe Brake Control (SBC), Safe Speed Monitor (SSM) and Safe Direction (SDI).

Removable I/O terminals provide for easy cabling and help save time in installation. The power cable terminals are located optimally for cabinet assembly, and a removable memory unit increases the flexibility of the drive and provides for easy maintenance.
