Product Description:
The PY0A015A0M21P00 is a servo amplifier manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. The unit links a motion controller to a brushless servo motor and modulates three-phase energy so the motor follows precise position commands in automated assembly stations, pick-and-place modules, and indexing tables. It converts incoming line power into controlled phase currents that correspond with incremental encoder feedback. This closed-loop arrangement allows the connected axis to maintain accurate positioning and repeatable torque delivery as operating loads change.
The amplifier has a current capacity of 15 A, allowing the power stage to supply the motor during acceleration and disturbance recovery. The power section accepts a 200 VAC three-phase input that is compatible with common industrial power systems. Feedback is processed at a resolution of 2000 P/R, dividing each motor revolution into 2,000 increments for fine position interpolation. A built-in regeneration network with a resistance of 100 Ω dissipates excess kinetic energy during rapid deceleration, and the circuit has a power rating of 20 W. The control logic operates in position control mode, in which incoming pulse trains are converted into commanded shaft positions. The controller compares each command with encoder data and adjusts motor current to correct position error in real time.
A matched motor reaches its continuous operating point at 3000 rpm, where it produces 0.191 N·m of rated torque while drawing an armature current of 0.7 Arms. Short torque bursts of up to 0.647 N·m help overcome static friction and accelerate the load from a stopped position. The housing weighs 2.2 kg, which must be considered when selecting panel supports and mounting hardware. The control electronics draw 40 VA from the auxiliary supply, while the main power stage uses a 0.3 kVA power path. The connected servo motor can accelerate to 4,500 rpm when operating conditions remain within the applicable thermal limits. Adequate cabinet ventilation helps control heat generated by the amplifier and the internal braking circuit during repeated acceleration and deceleration cycles.
