Fast set-up and diagnosis with real-text display, plus integrated CODESYS based PLC.
M400 minimizes machine downtime with its optional intuitive advanced LCD keypad that offers real-text multi-language display for rapid set-up and superior diagnostics. Its onboard PLC with real-time tasking can be used for simple logic control using Machine Control Studio programming software (powered by CODESYS) to enhance drive application capability.

Maximize productivity with high performance control of AC motors.
Unidrive M400’s advanced Rotor Flux Control (RFC) algorithm ensures maximum stability and machine control. It provides a high bandwidth motor control algorithm with 166 μs current loop update rates and 180 % motor overload for heavy industrial machinery applications.

Maximize throughput and easily meet machine safety requirements.
Unidrive M400 has onboard dual Safe Torque Off (STO) inputs for easy safety system integration, eliminating external components such as contactors. Compliance with SIL3 is simple while machine productivity is enhanced.

Robust design.
After extensive customer research, Unidrive M400 has been designed and tested for leading reliability in manufacturing environments. It features: 
- Unique advanced cooling design featuring a patented flow system that helps cool the drive more effectively while protecting internal components.
- Conformally coated PCBs 
- 180 % overload for 3 s or 150 % for 60 s 
- Wide supply voltage tolerance
- Drive meets IP21 as standard 
- Higher temperature operation with de-rating 
- Intelligent 3 speed user-replaceable cooling fan with patented fan-fail detection circuit.

Fast parameter transfer without mains power.
For fast, serial machine production the AI-Back-up Adaptor option plugs into the top of the drive to allow configuration settings and Machine Control Studio programs (powered by CODESYS) to be copied without the need to apply mains power. Files are stored on an SD memory card for easy handling.

Enhance productivity through easy integration with automation systems and reduce machine downtime.
Unidrive M400 provides optional RS485 communications and a port for a System Integration (SI) option module. SI modules include Ethernet, EtherCAT, PROFIBUS, DeviceNet and CANopen network communications, and additional I/O. These allow remote control and diagnostics across different networks, while I/O can be configured to accept an encoder or frequency/direction inputs for frequency following.

Reduce machine size and cost.
Unidrive M400’s compact drive dimensions are among the smallest in class at every power rating. Packed full of onboard features, such as programmable automation for simple applications and 2 x STO terminals, Unidrive M400 provides a powerful economical solution, eliminating the need for many external components such as PLCs and safety contactors.

Easy to access machine control features.
Our software tools, keypads and memory storage devices provide easy and fast access to Unidrive M’s machine control features for configuration, monitoring and diagnostics.

Powerful and easy field service and upgrade.
The M400 is designed to extend the field service life of previous generations of products. It also provides the easiest possible upgrade for OEM machine designs that currently use Commander SK drives in high power applications or where a LogicStick is used. Features include: 
- Compatible dimensions 
- Onboard programming 
- Extended power ratings up to 110 kW (150 hp) 
- Support for the import of Commander SK parameter files and drive cloning.
