Product Description:

The PY2A015A0M51P00 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. It interfaces with position-control motion systems to modulate current for a matched Super BL motor, providing closed-loop precision in automated assembly, packaging, and electronic pick-and-place equipment. By converting incoming mains power into controlled armature power, the unit supplies torque commands and executes dynamic braking to stop motion rapidly when the control logic issues a stop command.

This amplifier is rated for a continuous output of 15 A, allowing it to drive medium-inertia servomotors without reaching current limits. Its power stage is designed for 200 VAC industrial supplies and accepts a three-phase feed, helping maintain balanced line loading in multi-axis cabinets. Position commands arrive over a differential input that can decode up to 2 million pulses per second; this bandwidth supports high-resolution trajectory profiles generated by modern motion controllers. Current loops and velocity observers remain stable up to 400 Hz, enabling responsive correction of load disturbances. A brake delay of 10 ms engages the internal dynamic brake after mains power is removed, preventing excessive motion while limiting mechanical stress on the connected equipment.

The brake circuit can absorb 360 J of energy, and the design omits a regenerative resistor, so excess kinetic energy is dissipated internally rather than returned to the DC bus. Velocity can be regulated across a 1:5000 range, which suits applications that shift from slow indexing to rapid traverse within a single operating cycle. An incremental encoder with a 2000 P/R signal supplies position feedback that supports the amplifier’s control response. At 1.5 kg, the housing can be mounted on a DIN rail without placing excessive load on light control panels. The 0.5 G vibration rating permits operation on machinery frames exposed to moderate dynamic loads during routine production cycles.
