Product Description:
Sanyo Denki manufactures the PY0A150E0XXYPH3, a servo amplifier within the PY Super BL Servo Amplifiers series. This unit conditions power and command signals for a brushless servo motor, producing precisely regulated phase current so motion controllers can execute accurate position, velocity, or torque loops in automated machinery. By integrating protective circuitry and regeneration hardware, the amplifier supports high-cycle indexing, packaging axes, and electronic gearing stations without requiring external braking components.
The amplifier processes incoming velocity and torque references with a frequency response of 400 Hz, allowing the control loop to follow rapid command changes without significant phase lag. The internal velocity regulator spans a ratio of 1:5000, so low-speed creep and full-speed traverse can be driven from the same command. Torque demand enters through a differential input scaled to ±2.0 V at 100% torque; this reference range simplifies the use of shared controller outputs across multiple axes. Overcurrent protection is tied to a limit input calibrated at ±2.0 V ±10% at rated current, while diagnostic circuitry reproduces the actual phase current through a monitor pin scaled to 2.0 V ±20% at rated current. A separate velocity monitor outputs 2.0 V ±10% at 1000 rpm, enabling oscilloscope checks of servo performance during setup and operation.
Thermal management and power-dump hardware are installed within the amplifier rather than housed externally. A dynamic brake engages after 24.0 ms, discharging residual motor energy into an internal resistor network with an effective rating of 120 W and a fixed resistance of 6.7 Ω. Regenerative processing routes smaller energy surges back to the DC link, while the built-in cooling fan helps maintain acceptable component temperatures. The amplifier can operate at installation altitudes up to 1000 m when mounted with the required airflow clearance. The housing weighs 8.5 kg, so the panel must provide sturdy mounting rails and sufficient vertical space for cooling airflow.
