Product Description:

The PB2D003R1UT from Sanyo Denki belongs to the PB SANMOTION Servo Drivers series. It is designed for precise and reliable motor control in various automation tasks. This compact unit supports up to four control axes.

The PB2D003R1UT features closed-loop control. This design prevents step-out and micro-vibration when the motor stops. The command resolution ranges from 200 and 12,800 pulses per revolution. Operating temperature ranges from 0 to +55°C with storage capability from -20 to +70°C. It has rotating speeds ranging from 0 to 4500 min⁻¹. The driver uses a control circuit power supply of 24 VDC ± 10% and 1.5 A current. The main circuit power supply requires 24 or 36 VDC at ±10% and 15 A. The product handles operating humidity up to 90% RH without condensation. The communication interface employs RS-485 start/stop sync in half-duplex mode. The input signals are EXE, POINT, SELECT, and ALMCLR. It is made in an open frame structure and has a compact width of 86 mm. It weighs approximately 0.5 kg which suits tight installations. It supports high torque at low speeds that improvise positioning time in short-stroke applications. Protection features cover power supply errors and regenerative voltage faults. The unit safeguards against overspeed and driver overheating. It also includes overload stop, encoder disconnection and CPU error detection.

The Sanyo Denki’s PB2D003R1UT ensures precise multi-axis control with robust protection functions. It is ideal for industrial automation demanding stable operation under varied environmental conditions. The servo driver’s compact design and advanced control features deliver reliable performance. This product is engineered for users requiring smooth and vibration-free motion with high positional accuracy. The PB SANMOTION Servo Drivers series offers an excellent balance of power, control and protection in a small footprint.

Frequently Asked Questions about PB2D003R1UT:

Q: How does the RS-485 half-duplex interface improve communication for PB2D003R1UT?

A: The RS-485 half-duplex interface allows reliable data transmission over long distances with noise resistance. It reduces wiring complexity while maintaining synchronized control signals for multiple axes.

Q: Why is the open frame structure important for the PB2D003R1UT servo driver?

A: The open frame design enhances heat dissipation by allowing airflow around components. This helps maintain stable operating temperatures and prolongs the driver’s lifespan.

Q: How does the closed-loop control prevent micro-vibration in PB2D003R1UT?

A: Closed-loop control continuously monitors motor position and adjusts signals in real time. This feedback reduces positional errors and smooths motion during stop phases.

Q: What is the benefit of supporting a wide command resolution range in PB2D003R1UT?

A: A resolution range from 200 to 12,800 p/r enables precise control over various motor speeds and positions. This flexibility suits applications requiring both coarse and ultra-fine movements.

Q: How does the high torque at low speeds feature improve PB2D003R1UT performance?

A: It enhances responsiveness in short-stroke or slow-speed tasks by providing consistent force. This reduces positioning time and improves accuracy in delicate operations.
