Closed or open loop vector control for outstanding regulation, torque production, and position control capability.
Continuous Auto-tuning optimizes performance by compensating for changes in motor temperature.
High Frequency Injection enables high precision open loop control of Interior Permanent Magnet Motors.
Fast acting current and voltage limiters help achieve continuous drive operation during periods of excessive demand.
High Slip Braking reduces installation cost and the need for dynamic braking resistors
Communication options for all major industrial networks provides high speed control and monitoring, reducing installation cost.
DriveWizard computer software and Application Sets for easy configuration.
Auxiliary Control Power Unit maximizes production time and efficiency by maintaining network communication while main power is removed.
Embedded Safe Torque Off minimizes downtime for applications requiring occasional intervention (SIL CL2, PLd, Category 3).
Embedded function blocks, programmable with DriveWorks EZ, provide additional application flexibility and the opportunity to eliminate separate controllers.
USB Copy Unit and Keypad configuration storage provide speed and convenience for duplicate configuration of multiple drives.
Removable terminal board with configuration storage provides convenience of configuration backup.
Made with RoHS compliant materials.
Integrated DC Reactor (standard on 30HP and larger) for input harmonic reduction.
Kinetic Energy Braking allows drive to remain in control during momentary power losses.
Integrated 12 Pulse version provides a cost effective solution for low harmonics.
Flange version provides NEMA 12 backside integrity when mounting with heatsink external.
