UME 7008 Step motor - power stage

The isel stepper motor power board UME 7008 is a micro-step power output stage for bipolar 2(4)-phase stepper motors. The output stage operates using the

bipolar constant current principle and supplies the motor with an adjustable phase current up to 8 A.

A switched-mode power supply operating at approx. 18 kHz provides for low-noise operation and ensures optimum running behaviour of the connected stepper motor.

For controlling, the output stage provides signal inputs for clock, direction, boost and reset. These are designed both as Schmitt trigger inputs (earth reference to supply voltage) and as optically isolated inputs.

The output stages are protected from overtemperature, overcurrent and shortcircuit by appropriate protective circuits. The individual operating conditions are indicated by LEDs on the front panel.

For installation into 19” subracks, the modules are provided with connectors to DIN 41612.
