Microstepping driver
20 - 160 VDC, 3 - 9 A | SMD41, SMD42
JVL
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
