Step and Direction LAM Technologies manufacturers a wide range of bipolar stepper motor drives, pulse train controlled, with the traditional STEP and DIRECTION signals.

We offer drives designed to be mounted on DIN rail (DS10 series), open versions for panel mounting (OS10 series), very compact versions for wall fixing (LS10 series) and finally modules for PCB mounting (USD series).

The fractionation step reaches 25600 steps per revolution and the maximum input frequency exceeds 300KHz.

The power range is extraordinarily wide and includes models with supply voltage from 18Vdc up to 240Vdc and current from 0.3Arms up to 10Arms (corresponding to 14Apk or 14Imax). Within the same family the various models share the same electrical connections and mechanical fasteners and this makes easy and quick the migrations upwards or downwards of one's own application.

Many models are supplied also with the AC input (alternating current) which, thanks to the integrated power supply, can be directly connected to the transformer.

The high performance, the compact size, the availability from stock and the low cost have for years determined the success of our microstepping drives, controllable with STEP and DIRECTION signals, which are successfully used in applications including pantographs CNC, labelling, plasma and laser cutting, cartesian robots, solar chasers, etc.
