Product Description:

The PY0A150E0XXYPH1 is a servo amplifier manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. As a drive unit, it modulates DC-bus energy into three-phase outputs that energize matched brushless servomotors used in positioning tables, feeders, and other industrial axes. The amplifier regulates current, velocity, and position feedback so the connected motor can deliver repeatable torque under changing loads. Within an automation cabinet, it links the machine control layer to the mechanical actuator and closes the electromechanical control loop.

The power stage accepts an AC supply of 200 VAC and rectifies it onto an internal DC bus rated for 24.0 A of continuous current. When line power is applied, the charging circuit momentarily draws 18 A for about 600 ms, so upstream circuit breakers must accommodate that peak. The bus is supported by a power supply that can deliver 8.3 kVA, and the switching devices dissipate 260 W of heat that must be removed by panel airflow. With this input, the amplifier can support up to 5000 W of continuous motor output and sustain 18.1 Nm of shaft torque with the specified motor. Both the bus and motor phases require copper conductors with a cross-sectional area of at least 8 mm² to carry the listed current safely.

Low-level logic and encoder power require only 40 VA, yet the control section can draw a surge of 40 A for 1 ms when the amplifier first energizes. The 0.2 mm² control wiring must therefore be kept short and firmly terminated. The amplifier can operate at a relative humidity of up to 90% under noncondensing conditions and withstand mechanical shocks of 2 G. These limits should be considered when selecting an enclosure and preparing the unit for transportation. The dedicated thermostat circuit uses 0.5 mm² leads so that temperature feedback remains accurate in the presence of internal electrical noise.
