Nidec ASI Unidrive M800 AC Drives

Frequency converters Unidrive M800, Unidrive M810 – the most versatile and multifunctional Unidrive M series AC electric drives in the production program Nidec ASI. 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.

Technical characteristics of the Unidrive M800/M810 electric drive

• Rated power: 0.75 kW – 1.2 MW; 
• Supply voltage ratings: 200 /400 /575 /690 In; 
• Integrated Programmable Logic Controller (PLC) MCi200 (M800) and MCi210 (M810); 
• 2 built-in RS485 data transfer ports; 
• 2 slots for additional modules; 
• Built-in EMC filter with simple shutdown, 
• The ability to connect external EMC filters and brake resistors .

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). 

List of electric motors compatible with Unidrive M800 /M810 frequency converters

• asynchronous AC electric motors; 
• asynchronous servomotors with a short-circuited rotor; 
• synchronous servo motors with permanent magnet rotor; 
• linear electric motors. 

Modes of operation of Unidrive M800 /M810 frequency converters

• U/f (volt-frequency) control /scalar control of an asynchronous electric motor; 
• vector control in an open loop by an asynchronous electric motor; 
• vector control in an open loop using the RFC-A algorithm. 
• open loop control for permanent magnet motors, RFC-S mode (without using a feedback sensor);
• closed-loop vector control for asynchronous motors, RFC-A mode (using feedback sensor/encoder); 
• closed-loop vector control for permanent magnet electric motors, servo motor, RFC-S mode (using feedback sensor, encoder, resolver); 
• active rectification mode Active Front End /AFE (ensuring energy recovery and reducing unwanted harmonics). 

Configuration of inputs/outputs of the Unidrive M800/M810 electric drive

• 3 digital inputs + 3 digital outputs; 
• 1 built-in relay for current 2A AC 240 V;
