Unidrive M400
Flexibility For Countless Applications.
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.
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.
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.
The Rotor Flux Control (RFC-A) mode gives maximum stability and control over induction motors at all powers.
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.
Unidrive M400 drives have integrated dual Safe Torque Off (STO) inputs, certified to SIL3 / PLe, providing an elegant and reliable safety solution.
