Compact Ministepdrivers From Jvl
New step motor driver from JVL
Mini-step Driver gives smooth motor operation
Mini-step Driver SMD41 from JVL has had great overall success. It fulfils the requirements for a small compact unit which is easily incorporated into control systems. It is available in 3 - 6 and 9 A models, all with a supply voltage of between 15 and 80 Volt. In addition, a range of Drivers with various step resolutions are available: models with full-step, half-step, 1/4 and 1/8 step, and models where resolution can be selected between 10, 25, 50 and 125 ministeps. Thus resolutions up to 25000 ministeps/revolution can be obtained. All models are supplied with the special feature of selectable step curve sequencing which provides optimum matching for different types of step motor.
The use of ministeps instead of the more commonly used full or half step gives significantly smoother motor operation and excellent positioning accuracy.
These drivers provide many additional advantages: error output, optically isolated inputs and outputs, automatic switching between operating and stand-by current, and a facility for external control of current. These features make them universally applicable for many tasks in the field of motor control.
As standard, the Ministep Drivers are constructed for mounting on a heat sink or a machine in proximity to the motor, thus avoiding long cabling. The drivers can also be supplied mounted on a heat sink for mounting in Eurocard racks and for mounting in a control cabinet..
