ABB ACS850 machinery drive
ACS850 is series of machinery drives to control standard asynchronous motors, motors with permanent magnets or active synchronous motors with rated power up to 560 kW (at 500V).
Industrial ABB drives are drives of alternating current with enhanced control flexibility which are intended for the use in industry, especially in such processing industries as a pulp and paper production, metallurgical, mining, cement, chemical and petroleum industry, and also power industry.
Drives can be configured exactly in accordance with the requirements of these industries, therefore ABB Corporation supplies the systems configuration of which conforms to the requirements of customer. Due to possibility to work in the wide range of power and tension and to the large variety of built-in and additional functions, and also simplicity of programming, drives easily adapt oneself for different application domains.
The basic values of current of ABB machinery drives are designed for systems with high demands for overload.
Drives are produced on the basis of Direct Torque Control platform (Direct management a twisting moment - DTC), which provides the exact static and dynamic adjusting of speed and twisting moment, high starting moment, and also allows to apply long cables for connecting of motors. For the organization of closed loop it is possible the use of the encoder (install the feedback module is needed).
Besides, a built-in additional equipment allows to facilitate and accelerate mounting of the drive. As a construction of drives is counted on a long period of exploitation, such wear components such as fans and capacitors selected with the most term of service. In combination with the wide set of protective functions and such elements of construction as printed circuit boards with additional coating, it provides the high degree of reliability of the offered equipment.
The industrial ABB drives are intended for system integrators and/or manufacturers of complete equipment, which create the own systems. Housing of the modules usually correspond to protection class IP20.
ACS850 04 single drives are fully complete devices. For them the large variety of the built additional equipment is foreseen, such as different modules of input/output and connection. Also there is a wide choice of external additional equipment.
As modules are intended for mounting in a closet, they can be set side-by-side, close to each other.
Benefits of ACS850 drives:
-compact design (optimal for installation in a Cabinet);
- easy setup;
-DTC algorithm of the motor control;
-built-in communication channel between drives
-built in SIL3 safety feature;
-wide range of additional options.
