Product Description:
The PY2A015P3 is a servo amplifier supplied by Sanyo Denki within the PY Super BL Servo Amplifiers series. It forms the interface between a motion controller and a brushless servomotor. The amplifier manages current, velocity, and emergency braking so that precision axes in industrial robots, pick-and-place heads, or electronic assembly stages follow programmed profiles without mechanical overshoot.
This model delivers a continuous output of 15 A, establishing the maximum motor phase current that the drive can regulate under rated conditions. Loop tuning is supported by a frequency response of 400 Hz, allowing the controller to correct position errors quickly. If an uncontrolled shutdown occurs, the dynamic brake engages after only 10 ms, and its resistor can absorb up to 360 J of kinetic energy before reaching its thermal limit. The current monitor outputs 0.5 V ±20%, providing an analog reference proportional to the real-time motor load. The amplifier does not have a built-in regeneration resistor, so external dissipation hardware must be added where repetitive deceleration cycles are expected. Velocity feedback enters through the wiring-saved absolute sensor control unit, and the velocity monitor uses the same scaling as the current monitor for consistent diagnostics. Electrical safety is supported by an M4 earth terminal screw. The amplifier does not provide a ready output signal, so the system logic must verify its status through another available signal.
Main power uses a single-phase feed connected to a 200 VAC power unit with a dynamic brake, allowing installation in plants that lack three-phase service. Closed-loop operation covers a speed range of 1:5000, supporting slow indexing and rapid traverse without requiring gain adjustments between operating modes. The chassis withstands shocks of up to 2 G during transportation. The complete assembly weighs 1.5 kg, which reduces the load placed on cabinet mounting rails. Mechanical fastening requires a tightening torque of 1.18 N·m on the designated hardware to maintain secure electrical grounding and resistance to vibration.
