PB SANMOTION Servo Drivers

The PB SANMOTION Servo Drivers are compatible with either single-phase 100/115V or single/three-phase 200/230V AC power sources, merging the robust low-speed torque characteristics of stepping motors with the precision offered by closed-loop control systems. Using sine wave PWM control technology, the system achieves high resolutions up to 3200 P/R, enhanced by its electronic gearing capability. Motors between the 42mm and 60mm range can achieve speeds from 0 to 4500 min-1, whereas the larger 86mm models have a maximum speed of around 4000 min-1. Equipped with pulse-chain input and RS-485/parallel I/O interfaces, the series includes five different motor models sized between 42mm and 86mm. The performance range boasts maximum stall torque between 0.39 and 6.6 N•m and rotor inertia ranging from 0.056 to 3 kg-cm². Additionally, its intelligent current control feature allows for significant heat efficiency, reducing heat production by as much as 80% relative to prior models. Position accuracy is also greatly improved, with encoder resolution reaching up to 4000 P/R, supported by a unique position compensation capability. Other notable functionalities include a digital operational interface for effortless parameter setup, teaching mode, and built-in protections to prevent the motor from overheating.
