PG-B3 Open Collector PG-Interface 50kHz

Why Choose the Yaskawa PG-B3 Encoder Feedback Option Card?

The Yaskawa PG-B3 is a pulse generator (encoder) feedback option card designed for use with Yaskawa 1000-series inverter drives such as the A1000, U1000 and related models. This module allows the drive to receive speed feedback signals from an incremental motor encoder, enabling more accurate motor control and improved dynamic performance.

By installing the PG-B3 option card, the drive can read encoder signals from a pulse generator mounted on the motor shaft. This feedback allows the inverter to detect changes in motor speed or load and automatically adjust output frequency to maintain precise speed regulation.

The card supports advanced control modes including V/f with encoder feedback and closed-loop vector control, improving torque response and speed stability in demanding industrial applications such as conveyors, hoists and machine tools.

Precision Motor Control with Encoder Feedback

In applications requiring high precision, motor speed must be measured and continuously corrected. Encoder feedback option modules such as the PG-B3 allow the drive to monitor motor rotation directly using an incremental encoder attached to the motor shaft.

This feedback enables tighter speed regulation, improved torque control and better dynamic response, which are essential for demanding industrial automation processes.

Typical Applications

• Closed-loop vector motor control systems.
• Conveyor and material handling equipment.
• Hoisting and lifting machinery.
• Machine tools and precision motion systems.
• Industrial automation systems requiring encoder feedback.
