Stepper Motor Ministep Drivers SMD41 and SMD42

For particularly smooth motor operation
For particularly smooth and precise motor operation, JVL''s very compact Ministep Drivers are recommended. Model SMD41 operates with 20-80VDC supply voltage while model SMD42 operates with 20-160VDC supply voltage for highly dynamic applications. The drivers are available in 2 basic models, each of which is available in 3A, 6A, and 9A versions. Operating frequency 0 to 800 kHz

Step resolution 200, 400, 800, 1600, 2000, 5000, 10000 and 25000 ministeps per motor revolution
Galvanically isolated step-pulse and direction inputs
"Power dump" output for sinking surplus energy
Automatic switching between stand-by and operating currents
Facility for controlling operating and stand-by currents via externally applied voltage 0-2.5V or 0-20 mA
Small physical dimensions: 100x22x114mm
Error output for temperature overload and short-circuit
Thermally protected Filter option at step-pulse input
Can be connected to both 2 and 4-phase motors
