Product Description:
The PY9A300U0XXXC01 Servo Amplifier is a compact and efficient motion control unit developed for use in industrial automation. This amplifier is designed to work seamlessly with compatible servomotors.
The PY9A300U0XXXC01 servo amplifier supports a velocity control range of 1:5000 that enables high resolution motor speed regulation across both low and high RPMs. It achieves a load variation tolerance of ± 0.1 % for stable output speed under fluctuating torque conditions. This level of precision is ensured through high speed current loop processing and advanced vector control algorithms. This model accepts two types of analog command inputs: velocity and torque. For velocity control, a command voltage of ± 2.0 V DC corresponds to a motor speed of ±1000 min⁻¹ (RPM) with 0 V DC representing zero speed. For torque control, a command voltage of ± 2.0 V DC corresponds to ± 100 % of the rated torque output with 0 V DC indicating zero torque. Both inputs exhibit a linear response and are symmetrical around 0 V DC. Each input channel has an input impedance of approximately 10 kΩ and is processed through internal differential amplifiers that allows compatibility with both single ended and differential voltage sources. The analog input stages are designed with low noise and low offset characteristics to ensure accurate and stable command signal interpretation.
This Sanyo Denki PY9A300U0XXXC01 servo amplifier integrates a built in tray type switched mode power supply (SMPS) to ensure stable and efficient power conversion and distribution. It features internal regenerative energy processing circuitry that dissipates or reuses excess kinetic energy during deceleration. This PY Super BL series servo amplifier is designed to operate within the specified load inertia ratio limits (typically ≤30:1) corresponding to the matched servomotor.
