AC Drives Control Techniques Unidrive M800

Frequency converters Unidrive M800, Unidrive M810 – the most versatile and multifunctional Unidrive M series AC electric drives in the production program Control Techniques. The 800 series electric drives are equipped with integrated MCi200 PLCs for Unidrive M800, MCi210 for Unidirve M810, programming is carried out using Machine Control Studio software based on the CODESYS industry standard, the presence of 2 built-in isolated Ethernet ports ensure high throughput.

Unidrive M800, M810 are designed for high-precision real-time electric drive control tasks in which additional software processing by speed, torque and position control modes is required.

The use of the optional SI-Safety module provides an "intelligent" programmable solution for compliance with the IEC 61800-5-2 functional safety standard.

Distinctive features of Unidrive M800 electric drives

• built-in programmable logic controller MCi200, 
• built-in Ethernet communication network port; 
• the construction of automated control systems in which it is necessary to differentiate (separate) the functionality between the control system of logical operations (PLC, PLC) and the motion control system (electric drives, frequency converters); 
• easy integration with I/O devices, HMI interfaces, control panels, controllers; 
• scaling solutions with complex functionality; 
• reducing the cost of a complete control system for technological equipment.  

Distinctive features of Unidrive M810 electric drives (in addition to Unidrive M800)

• the use of an electric drive as a full-fledged controller for controlling technological equipment (refusal to use an additional PLC). The control of the system is completely delegated to the electric drive; 
• built-in programmable logic controller MCi210; 
• extended controller program memory; 
• 2 built-in isolated Ethernet communication network ports (high bandwidth, processing a large amount of data in the network, high noise immunity).
