- Step Motor Servo System (i-STEP MOTOR)

Cutting Edge i-STEP motor
Providing superior performance and smooth operation, when precise positioning control is needed.
i-STEP MOTOR (Motor & Driver) is a step motor servo system which controls step motors via a closed loop. Smoother high speed drive is realized by general-purpose pulse row drive.
Features
- High speed drives (Max.4000min-1) is possible at DC 24V.
- Precise positioning is possible because there is no position deviation due to malfunction.
- Stable stop and its retention is possible because there is no micro vibration at the time of stopping.
- Operates without adjusting gain.
- Easy to command by pulse row input.
- Smoother high speed rotation is possible by dividing the resolution (from 200 to 25,600) into 8 steps.
- Motors are available in RoHs compliat.
