A world of

transmission at
your fingertips

Scots Bearings Ltd are proud to promote the Lenze SMD frequency inverter range that provide advanced technology and high quality at a reasonable price – you will not be forced to compromise. The SMD covers a power range from 0.25 ... 22 kW and features everything you would expect from a modern frequency inverter suitable for universal use. A relatively small number of functions can be used to provide complete yet simple solutions for a multiplicity of standard applications.

Just three on-board functions and a handful of parameters are all you need – commissioning is child’s play. Parameter settings can be saved on a unique chip. The electronic programmable module (EPM) is a plug-in memory chip which has been designed specifically for the SMD.

With the EPM, drive data only needs to be configured once and can then be transferred to other frequency inverters in the range. Even modifying drive parameters take just seconds – simply replace the EPM on the front panel of the frequency inverter.

Programming takes place directly on the inverter or using a battery-powered EPM programming device. This means that configurations can be created or edited easily offline. The programmer can save up to 30 different drive programs as files.

Copying from EPM to EPM, file to EPM or rewriting the EPM to a file takes just two seconds at the touch of a button. The frequency inverter features integrated motor overload protection. For this purpose, a microprocessor calculates the motor load independently of the output speed, protects the motor and renders additional hardware superfluous.

The function and number of control terminals corresponds to the familiar Lenze standard:

Start/stop functions

Analog set point selection with voltage or current

Freely programmable inputs

Freely programmable relay output

The SMD features current limitation with frequency reduction for stable operation, a highly visible LED display and the option of low-noise operation by means of an adjustable switching frequency up to 10 kHz.
