PG-B3 Open Collector PG-Interface 50kHz

Why Choose the Yaskawa PG-B3 Complementary Type PG Option Card?

The Yaskawa PG-B3 is a dedicated pulse generator feedback option card designed for compatible Yaskawa AC inverter drives. It allows the drive to read feedback signals from an incremental encoder or pulse generator mounted to the motor, helping improve speed control accuracy, response and overall motor performance.

This option card is especially useful in applications where more precise motor feedback is required than standard open-loop control can provide. By connecting a compatible encoder to the drive, the PG-B3 supports feedback-based control methods such as V/f with PG, closed loop vector control and advanced open loop vector control where supported by the drive.

The PG-B3 supports complementary encoder feedback and can also be used with suitable open-collector pulse generator signals. It is designed for industrial machinery, lifting systems, process equipment and drive applications where accurate speed regulation, improved low-speed performance and reliable feedback monitoring are important.

Accurate Encoder Feedback for Drive Systems

Pulse generator option cards such as the Yaskawa PG-B3 allow an inverter drive to receive feedback from an encoder fitted to the motor shaft. This feedback helps the drive detect actual motor speed and adjust output frequency more accurately, improving speed regulation and response under changing load conditions.

The PG-B3 is particularly useful where stable motor speed, low-speed torque performance or accurate load response is important. By adding encoder feedback to compatible Yaskawa drives, engineers can improve drive performance in machinery where open-loop control may not provide sufficient accuracy.

Typical Applications

• Yaskawa AC drive encoder feedback applications.
• Closed loop vector motor control systems.
• Lifting, hoisting and positioning machinery.
• Conveyors and material handling systems.
• Process machinery requiring accurate speed regulation.
• OEM machine building and industrial automation panels.
