PY0A300A0PW1PK0 by Sanyo Denki

The Sanyo Denki PY0A300A0PW1PK0 servo amplifier offers precision control and robust performance as a member of the PY Super BL Servo Amplifiers series. Engineered for industrial automation, it delivers rapid torque response and consistent speed regulation under variable load conditions. An integrated dynamic braking circuit ensures rapid deceleration, while regenerative energy processing captures and returns excess power to the system bus. Durable construction and enhanced sealing enable reliable operation in demanding environments. This amplifier is optimized for motion control systems requiring high responsiveness and energy efficiency.

All critical components are engineered for durability and serviceability. The main body is constructed of SPCC chromated steel and the front panel employs a resin sheet for lightweight protection. Electrical connections utilize M6 primary terminal screws with a tightening torque of 5.4 N·m, and M4 secondary terminal screws torqued to 1.18 N·m for secure retention. A regenerative resistance element is included to manage energy dissipation, and rubber packing provides enhanced sealing against dust and moisture. Identification elements include an amplifier model number on the front panel display and a nameplate located on the left side at a scale of 1:1 alongside a warning label scale of 1:1.

Operational performance is optimized through a frequency response bandwidth up to 400 Hz when motor and load inertias are matched (JL=JM), minimizing phase lag and maximizing closed-loop gain before the -3 dB point. The dynamic braking circuit dissipates kinetic energy through a braking resistor to prevent overshoot during emergency stops. Regenerative processing captures deceleration energy, feeding it back into the power supply or system bus for improved efficiency. Continuous monitoring is provided by dedicated analog outputs: the Velocity Monitor Output (VMO) delivers 2.0 V b110% at 1000 minb9 with linear scaling, and the Current Monitor Output (IMO) provides 2.0 V b120% at rated armature current proportionally across the operating range. A digital display interface reports internal status, fault codes, and real-time alarms for rapid diagnostics and system protection.

System integration is streamlined using standard industrial protocols and compatibility with common DC bus configurations. The rear side mounting orientation and robust SPCC frame support seamless installation in cabinet or panel assemblies. Target applications include packaging machinery, CNC automation, assembly lines, and any motion control environment demanding precise speed and torque regulation with energy recovery features. The PY Super BL series amplifier family provides a scalable solution for manufacturers seeking high-performance servo control with regenerative functionality and compact design.
