Lenze SMD series contains only those functions that are needed by 80% of consumers and no redundant ones. This approach has resulted in the most economically priced frequency drive on the market, suitable for most applications. In addition, these frequency drives are very light to install and run, which will allow you to save on hiring highly qualified personnel.

Inverters SMD are a great disjunctive to benign starters, multi-speed engines, mechanical variators, DC discs.

Frequency inverter is an electronic device for changing the frequency of electric current. The main scope of these devices is changing the speed and torque of asynchronous electrical machines.

SMD frequency converter features:

Easily control your speed
controllable move.
capacity diapason: 0.25 to 22 kW (1.3 to 46 A).
especially appropriate for: transporter discs in intralogistics and pump drives.

The principle of operation of frequency converter is based on the dependence of the speed of rotation and the moment of force on the shaft of an alternating current motor on the frequency of the supply voltage.

Excellences:

compounds: beginning/pause
analog entrance
easily programmable numeric inlets and outllets (3/1)
fast and light commissioning
built-in engine overburden defense
obviously readable LED display

Where is a frequency converter used?

Frequency converters are used in industry to control the velocity of turning of asynchronous engines. The rotation speed is controlled by changing the frequency of the motor supply voltage.

EPM software element.

All Lenze SMD products provide original equipment manufacturers (OEMs) with the benefits of the EPM software element, a unique, highly reliable chip program that plugs directly into drives, reducing programming time to seconds. The EPM software mod ensures an instant copy of the drive parameters to the chip, after which the EPM module makes it possible to ensure that the drive is ready for almost error-free operation immediately after connection.

Functions:

speed control
acceleration
braking
reversal
protection of the motor against overload by current, stress, phase insufficiency
mover temperature control
slip compensation
DC braking
motorized potentiometer

Lenze SMD inverter is easy to program and operate as part of user equipment. Control functions are standardized and optimized according to motor control rules. Built-in protection against phase-to-phase, ground fault, overvoltage, motor jamming, and drive overcurrent.

Applications:

conveyors
transporters
pumps
fans
compressors
agitators
drive of high-speed spindles
winding equipment.

The drive's microprocessor software calculates motor parameters, optimizes settings, and provides overload protection. Lenze SMD inverters also feature variable frequency current limiting to stabilize motor speed, clear LED monitor and poor noise in the middle of operation (thanks to controllable shifting periodicity from 4 to 10 kHz).

This series inverter is characterized by affordable control, saving installation time, low price and high quality. All drives are equipped with a "Password" protection function that can be used to prevent unauthorized access to parameters.

Quick commissioning is possible thanks to the use of built-in function keys and preset settings for standard systems.
