MICROMASTER Inverter Vector Control (6SE31xx) – Dynamic control and production continuity

The MICROMASTER Vector series represents the evolution of the Classic platform, designed for applications where simple V/f control does not ensure sufficient stability and precision.

It is widely used in automatic lines and machines with variable loads, where drive stoppage causes immediate production downtime.

Why MICROMASTER Inverter Vector Control (6SE31xx) are still critical today

In many plants, their replacement requires:

machine regulation recalibration
PLC parameters and work cycle modification
mechanical interventions on moving parts
extended production downtime

For this reason, regeneration is often the safest solution to maintain process stability.


What MICROMASTER Inverter Vector Control 6SE31xx are

They are sensorless vector control inverters capable of precisely regulating torque and speed even with load variations.

Vector technology enables:

stable torque at low speeds
controlled acceleration
smooth operation without encoder
greater precision compared to V/f
