The all-rounder drive of choice for OEMs

Minimise downtime and system set-up The 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.
Improve throughput with advanced open-loop motor control algorithms The Rotor Flux Control (RFC-A) mode gives maximum stability and control over induction motors at all powers.
Reduce system costs by directly integrating with your applications The 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. An optional System Integrator module can be fitted to the drive for additional I/O or fieldbus communications.
Conform to safety standards by direct safety system integration Unidrive M400 drives have integrated dual Safe Torque Off (STO) inputs, certified to SIL3 / PLe, providing an elegant and reliable safety solution.
