Industrial BSD-110-012 Precision Controller Unit

Industrial BSD-110-012 Precision Controller Unit from Citizen Chiba Precision Co. is a 24 V DC, 3‑phase sine‑wave PWM driver designed for miniature linear actuators. It delivers a continuous output current of 1.2 A with a maximum rated output of 2.1 A, and accepts encoder feedback via φA/φB/φZ (open‑collector) alongside Hall sensor inputs φU/φV/φW, enabling precise position control. The controller supports encoder and command multiplication by ×1, ×2, and ×4 and includes a USB transceiver, a microcontroller, EEPROM, and serial I/O for configuration and integration with host systems. Public documentation for the BSD‑11D‑012 family lists a 24 V input, a positioning range of Z: ±2.6 mm, repeatable accuracy of 0.2 μm (linear) and 0.01° (rotational), and an encoder input frequency up to 320 kHz, making it suitable for high‑precision linear actuator control in automation applications.
