PFRA06A201 by Sanyo Denki

The Sanyo Denki PFRA06A201 is a high-performance module in the PY Super BL Servo Amplifiers lineup, delivering precise multi-axis control for industrial automation applications. Designed to operate with a Control Power Supply of 12–24 V DC and offering a Regulated 5 V output (max 10 mA load), this amplifier excels at driving six axes simultaneously. Featuring a Pulse encoder output with 90° phase difference, the PFRA06A201 ensures accurate position feedback and smooth servo motion. Its primary function is to manage position, velocity and torque control modes in complex machinery such as press brakes in Amada FBD-NT and HDS series.

Incorporating advanced technical specifications, the PFRA06A201 supports multiple analog inputs including Analog Input Type 3 for velocity/torque commands and Analog Input Type 4 for current limit commands. It provides robust Error Check @ >9600 bps with 3-bit CRC and Error Check @ 9600 bps via parity bit to maintain data integrity. The amplifier offers Serial encoder output in selectable sync modes (Manchester or start-stop sync) and a Output Type 8 line driver for encoder signals, ensuring high-accuracy positioning. Users can choose between built-in or external Regenerative resistor options following provided guidelines, enabling efficient energy recovery during deceleration.

Additional design features include flexible Terminal wiring using terminal screws for secure panel mounting and an I/O circuit output voltage of up to 30 V for interfacing with external devices. Status signals are delivered via Output Type 6 open collector outputs, while high-accuracy feedback is supported through resolvers or encoders. The PFRA06A201’s robust error-checking protocols and selectable sync formats enhance both safety and reliability. In industrial environments, this servo amplifier reduces downtime, simplifies wiring layouts, and maximizes throughput, making it an ideal choice for demanding automation tasks.
