Optimised throughput and energy efficiency in industrial applications<\/h2>\n

Unidrive M400 is exceptional at combining the ease of use of our general purpose range with the capabilities of our high performance Unidrive M Series.<\/p>\n

Add in an impressive I\/O count, dual Safe Torque Off (STO) and integrated PLC, all of which contribute to making the M400 an extremely capable drive.<\/p>\n

*Obsessives included<\/h2>\n

 <\/p>\n

The all-rounder drive of choice for OEMs<\/h2>\n\n\n\n\n\n\n
\u00a0Minimise downtime and system set-up<\/strong>
\nThe Unidrive M400 is designed with special attention to robustness and reliability. The multi-language, 3 line display, together with the intuitive navigation buttons aid set up and fast diagnostics.<\/span><\/span><\/td>\n<\/tr>\n
\u00a0Improve throughput with advanced open-loop motor control algorithms<\/strong>
\nThe Rotor Flux Control (RFC-A) mode gives maximum stability and control over induction motors at all powers.<\/span><\/span><\/td>\n<\/tr>\n
\u00a0Reduce system costs by directly integrating with your applications<\/strong>
\nThe M400 incorporates an onboard PLC which can execute Machine Control Studio (IEC61131-3) programs for logic control, sequencing, speed following and digital lock – removing the need for additional PLCs.
\nAn optional System Integrator module can be fitted to the drive for additional I\/O or fieldbus communications.<\/span><\/span><\/td>\n<\/tr>\n
\u00a0Conform to safety standards by direct safety system integration
\n<\/strong>Unidrive M400 drives have integrated dual Safe Torque Off (STO) inputs, certified to SIL3 \/ PLe, providing an elegant and reliable safety solution.\u00a0<\/span><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
