Compact VLT® quality

VLT® Micro Drive is a genuine VLT® fre­quency converter with unsurpassed
reliability, user-friendliness, con­densed functionality, and is extremely
easy to commission. Terminal num­bers are named in the same manner
as in the rest of the VLT® family.

Reliable and user friendly

The VLT® Micro Drive is a full member
of the VLT® family, sharing the overall
quality of design, reliability and user­friendliness.

Small drive
– big performance

Despite the compact size and the
easy commissioning, a VLT® Micro
Drive can be set up to perform per­fectly, even in complex application
set-ups. Approximately 100 param­eters can be set to optimize energy
eciency and operation.

User friendly

Plug-and-play Minimum eort – minimum time

Minimum commissioning Save time

Copy settings via local control panel Easy set up of multiple drives

Intuitive parameter structure Minimal manual reading

Complies with VLT® software Save commissioning time

Reliable

Optimum heat dissipation Longer lifetime

High quality electronics/capasitors Low lifetime cost

All drives full load tested from factory High reliability

Earth fault, temperature and short circuit
protection

Circuit boards well protected and coated Increased robustness

Small drive – high performance

Process PI-controller No need for external controller

Automatic Energy Optimizer (AEO) Less energy consumption

Automatic Motor Tuning (AMT) Exploit motor’s full potential

150% motor torque up to 1 minute Replace need for bigger drive

Flying start (catch a spinning motor) Lean operation – more up-time
