PY9A050U0XXXC03

The PY9A050U0XXXC03 from Sanyo Denki is a high-performance member of the PY Super BL Servo Amplifiers series, engineered for demanding industrial automation environments. This servo amplifier delivers a Rated Output of 4500 W and supports a Rated Revolution Speed of 2000 rpm, providing robust power and consistent velocity control. It is capable of producing a Rated Torque of 21.5 N·m while maintaining a manageable Weight (including Wiring) of 22.0 kg, facilitating straightforward installation and handling. Designed for heavy-duty applications, the unit integrates an efficient Torque Constant of 1.05 N·m/Arms and a Rated Armature Current of 24.1 Arms to optimize dynamic response and control precision. The compact form factor offers installation flexibility without compromising on performance.

Technical capabilities of the PY9A050U0XXXC03 are highlighted by its electrical and mechanical specifications. It provides a Continuous Stall Armature Current of 31.6 Arms paired with a Continuous Stall Torque of 32.0 N·m, ensuring dependable torque delivery under prolonged load. For peak demands, the amplifier handles an Instantaneous Maximum Stall Armature Current of 79.7 Arms and an Instantaneous Maximum Stall Torque of 70.0 N·m, safeguarding against transient overloads. The device’s Phase Armature Resistance of 0.043 Ω and an Induced Voltage Constant of 36.7 V/krpm are optimized for efficiency and rapid current control. The internal rotor dynamics are characterized by an Inertia (including Abs-e) of 58.2×10⁻⁴ kg·m², while a Mechanical Time Constant (sensor Not Included) of 0.68 ms ensures swift acceleration and precise positioning.

Operational features of this amplifier are tailored to maintain system stability and longevity. It supports a Maximum Revolution Speed of 2500 rpm, extending operational range beyond the rated speed for short durations. The design includes fewer internal noise filters than earlier models, yet improved internal circuitry sustains a high level of electromagnetic noise suppression. For retrofit or replacement scenarios, implementing external noise filters on the 200 VAC power source is recommended to ensure maximum system stability. Absent an internal regenerative resistor, the amplifier accommodates external resistors for energy dissipation during deceleration; in their absence, the front-panel “CHARGE” indicator lamp signals a five-minute capacitor discharge interval upon shutdown.

Integration into industrial systems is streamlined by its robust construction and straightforward mounting requirements. Weighing in at 22.0 kg, the amplifier benefits from installation on a simple metal sub-panel—preferably zinc plated metal or galvanized steel—for effective high-frequency grounding. To preserve longevity, avoid ingress of dust and debris by maintaining a clean environment or incorporating protective covers. When housed within an enclosed cabinet, ensure sufficient internal clearance or active cooling mechanisms to facilitate heat dissipation and uphold optimal operating temperatures.
