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.

Input signal
| Signal names | Functions | ||
|---|---|---|---|
| Input | Positive rotation(CW) / pulse | Photo-coupler ON:Moves one step in the forward(CW) direction. Refer to Fig.1 Tw=1ms |
SW3①:OFF SW3①:ON |
| Photo-coupler ON:Moves one step in the direction of direction signal. | |||
| Reverse rotation(CCW) / direction | Photo-coupler ON:Moves one step in the forward (CCW) direction. Refer to Fig. 1 Tw=1ms |
||
| Photo-coupler ON : CCW direction Photo-coupler OFF : CW direction |
|||
| Drive | Photo-coupler ON : Turn driving current on and sets the driver to ready mode. Photo-coupler OFF : Turn driving current off. |
||
| Alarm reset | Photo-coupler ON : Alarms are cleared. "Sensor error" and "Counter overflow" cannot be cleared with this input. To clear these errors, turn the counter reset input on or shut off power and turn it on again. Refer to Fig.1 Tw=1ms |
||
| ACD off | Photo-coupler ON : Turn Auto-Curret-Down function off. Photo-coupler OFF : Motor driving current transfers to the setting value of the switch SW2 when positive or reverse rotation signals are not inputted for more than 0.25 seconds. |
||
| Counter reset |
Photo-coupler ON : Resets the deviation counter. Alarm Items are all cleared. Refer to Fig.1 Tw=1ms |
||
Standard ON current of photo-coupler : 16mA(Input Voltage : 5V)
Pulse row input : 300kHz max.
Output signal
