Product Description:
The PY0A015A0SW1P00 is a servo amplifier manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. It functions as the drive interface between a motion controller and a brushless servo motor, delivering the power and feedback processing required for closed-loop positioning. The amplifier can support controlled motion in automated assembly systems, pick-and-place machines, and inspection equipment. By regulating motor current in response to controller commands and encoder signals, it corrects position errors as the connected axis moves under changing loads.
This model operates in Position Control mode, so current modulation maintains the commanded shaft angle instead of regulating speed alone. Its internal electronics require a control power supply of 40 VA, while the main power section operates from a 200 VAC bus. Motor phases receive power from a three-phase output stage, which produces the controlled waveform needed to drive the brushless motor. A built-in rush-current limiter caps main inrush at 18 A, and the separate control path has a ceiling of 40 A. An incremental feedback device with a resolution of 2000 P/R reports rotor position in 0.18-degree increments, giving the control loop detailed information about shaft movement. The supported frequency characteristics allow stable loop operation up to 400 Hz, helping the amplifier respond quickly to position commands and load disturbances.
The wiring-saved incremental encoder format reduces the number of conductors needed for feedback connections, simplifying cable routing inside the control cabinet. The amplifier has a mass of 2.2 kg, which limits the mounting load when several units are installed in a multi-axis rack. Its velocity control range of 1:5000 allows the connected motor to transition from slow indexing movements to high-speed transfers without requiring gain changes. The built-in dynamic brake applies braking force during emergency stops, helping the motor decelerate when normal drive operation is interrupted. Regenerative energy produced during rapid deceleration is processed internally, so an external regenerative resistor is not required. These functions allow the amplifier to manage commanded motion, braking events, and returning energy through its integrated power circuitry.
