UNIDRIVE M400
0.25 – 110 kW (0.33 – 150 hp)
100 V / 200 V / 400 V / 575 V / 690 V
Unidrive M400 minimizes downtime with an intuitive LCD display for rapid set-up and clear diagnostic help. The integrated PLC can execute a substantial range of sequencing and logic programs. Coupled with an impressive I/O count complete with two STO inputs and an SI interface for a fieldbus option or extended I/O, the feature set ensures Unidrive M400’s flexible integration with any system.
Unidrive M400 provides an upgrade path for existing Commander SK users who use LogicStick.
