70AS40b-E Servo driver

The ABB 70AS40b-E is a servo drive that is an important component in the field of industrial automation. It is commonly used to precisely control the movement of motors to achieve high precision and high performance requirements in various automation applications.
Servo drives are widely used in various industrial fields, such as machine tools, packaging machinery, printing machinery, textile machinery, logistics equipment and so on. They are responsible for receiving control signals and driving the motor to move at a predetermined speed and position, thus achieving a variety of complex actions and precise control in the automated production process.

The main parameters of ABB 70AS40b-E are as follows:
In addition to the IM151-7 CPU that supports PROFIBUS, the IM151-8 PN/DP CPU1 that supports PROFINET functionality has been added.
The CPU integrates three fully functional PROFINET interfaces with performance similar to the CPU314 feature 1 in the S7-300 series.
The working memory is 128KB and the unit instruction execution time is 100ns1.
The site width can reach 2 meters or can be expanded to 63 modules 1.
With 3 identical PROFINET interfaces, linear topologies can be easily accomplished 1.
Support RT and IRT communication in PROFINET 1.
As a PROFINET I/O controller, capable of connecting 128 I/O devices1.
Support PROFINET CBA function 1.
