This product uses a closed loop control to maintain positioning operation even during abrupt load fluctuations and accelerations. The rotor position detection sensor monitors the rotation. When an overload condition is detected, it will instantaneously regain control using the closed loop mode.

When an overload condition continues it will output an alarm signal, thereby providing reliability equal to that of a servo motor.

Like conventional stepping motors, it operates in synchronism with command pulses. This makes possible short stroke positioning in a short time.

Gain tuning for servo motors is critical, troublesome and timeconsuming. Since it operates like a stepping motor, there are no gain tuning requirements. It is ideal for low rigidity applications, such as belt and pulley system.

The AS Series is recognized by the UL/CSA Standards and conforms to EN Standards. [The products with the motor frame size of 42 mm (1.65 in.) are recognized with the UL Standards and conforms to EN Standards.] The CE Marking certifies compliance with the EMC and Low Voltage Directives.

Since it is a stepping motor, it has no hunting problem. Therefore, when it stops, its position is completely stable and does not fluctuate. is ideal for applications in which hunting would be a problem.

The driver employs advanced technology that produces smoothness comparable to a microstep driver. Its vibration level is incredibly low, even when operating in the low speed range. When frequent changes from low to high (or vice versa) speed operations are required, the use of the Resolution Select Function solves the problem. It provides resolution as high as 0.036? per step without any damping mechanism or other mechanical device.

It requires only one cable for connection between the motor and the driver. Wiring is much simpler compared with conventional servo motors requiring two cables, one for motor and the other for encoder. The cable can be extended to a maximum of 20 m (65.6 ft.) [10 m (32.8 ft.) for flexible extension cable], so the motor and the driver can be installed in locations far apart.

The geared types enable driving of large inertial loads and positioning at higher accuracy, while the industrial connector type provides IP65 of ingress protection against dust and water. It offers a wide range of models meeting the needs of various applications.
