About This Product

■Summary

・Equipped with resolver sensor ・AC/DC input ・Affordable price

■Hybrid control realizes easier-to-use and more reliable control

αSTEP is a stepping motor-based motor that performs unique control that hybridizes the advantages of "open loop control" and "closed loop control." It constantly monitors the motor position and automatically switches between the two controls depending on the situation. Open-loop control under normal conditions, making it as easy to use as a stepping motor

■High response

By taking advantage of the stepping motor's high response, you can move short distances in a short time. It can follow commands without delay and move.

■Holds stopped position without hunting

Since the motor stops using its own holding force without hunting during positioning, it is ideal for applications where vibration is a problem when stopping due to a low-rigidity mechanism.

■Tuning not required

Since it normally operates under open-loop control, positioning is possible without gain adjustment even when there are load fluctuations in belt mechanisms, cams, chain drives, etc. Closed-loop control during overload for more reliable operation

■Continues operation even with sudden load changes and sudden acceleration

Normally, it operates in open loop control in synchronization with commands. In the event of an overload, it immediately switches to closed-loop control and corrects the position.

■Outputs an alarm signal in the event of an abnormality

An alarm signal is output when continuous overload is applied, and an END signal is output when positioning is completed. Therefore, it has the same reliability as a servo motor.

■Smooth movement even at low speeds

The standard microstep drive and smooth drive function* suppress vibrations at low speeds and allow smooth movement.

■Single driver supports various motors

A single driver can connect various types of motors, from standard types to geared types. Maintenance is simplified because there is no need to change the driver model for each motor to be combined. The driver is also equipped with an automatic recognition function that identifies the type of motor connected. The rotor position detection sensor detects rotor position information by using changes in inductance due to changes in the spatial distance between the small teeth of the sensor rotor and the small teeth of the stator.
