The closed-loop stepping system SANMOTION Model No.PB combines the convenience of stepper motors with the reliability of servo motors. Equipped with an encoder for position detection, the stepper motor enables closed-loop control through feedback, achieving higher reliability and efficiency than conventional open-loop stepping systems with a simple configuration. Examples of Applications Features low vibration, low heat generation, and stable stopping, making it suitable for a wide range of applications. Semiconductor switching devices, medical and environmental analysis/instrumentation equipment, surveillance cameras, and spotlights, etc. All models of drivers and motors listed in this product manual, starting from products manufactured in October 2012, comply with the permissible limits for specific hazardous substances (cadmium, lead, mercury, hexavalent chromium, PBB, and PBDE) specified in Annex II of EU RoHS Directive (2011/65/EU). Additionally, the drivers are standard specifications that meet CE (EN specification)/UL requirements. The DC power input Type P · Type E drivers also meet KC certification requirements. AC power input motor models meet CE (EN specification)/UL requirements.

Features

Lower misalignment improves device reliability	By using a motor with an encoder for closed-loop control, it eliminates the misalignment (dislocation) issue that is a weakness of stepper motors. Even when the load increases, there is no misalignment, and it can move to the target position, thus improving device reliability. In addition, the encoder constantly confirms the rotor position. When an abnormality occurs, various alarms can be triggered, providing the same level of safety as servo motors.
Reduced Positioning Time	It can achieve high torque in the low-speed range, making it suitable for applications requiring extremely short movement distances (short-stroke, high-accuracy). During acceleration and deceleration, the motor's torque can be maximized, thus reducing positioning time.
Energy Efficiency	Current flowing through the motor is controlled based on the device's operating conditions, which minimizes heat generation and enables efficient operation.
Low Vibration	The actual speed of the motor is monitored, leading to lower vibration compared to open-loop stepper systems.
Stable Stopping	Thanks to the stepper motor’s advantage—holding torque—it does not exhibit oscillation (micro-vibration) that occurs in servo motors, thus enabling stable stopping.
Device Startup Support & Analysis Functions	Using the installation software (optional), parameter configuration and operating status monitoring can be performed via a computer. Examples of Monitoring Functions ·Position Information…Command position, actual position ·Speed Information…Command speed, actual speed ·I/O Signals…Dedicated inputs, general-purpose inputs ·Alarm Information…Current alarm status, history
Extrusion Operation	It can control the extrusion load, which makes the replacement of systems like pneumatic systems extremely convenient. It is also suitable for Z-axis drive of equipment such as placement machines and testers.
