Product Description:

The PY2A015A2 servo amplifier is produced by Sanyo Denki as a member of the PY Super BL Servo Amplifiers series. Intended for multi-axis positioning tables, pick-and-place heads, and precision feeders, the unit modulates motor current in real time. This enables closed-loop velocity and torque control that reduces cycle time and maintains repeatability within automated production lines.

At the power stage, the amplifier can deliver a continuous output of 15 A, matching the peak demands of medium-frame Super BL motors. Its logic section is supplied by a single-phase 200–230 VAC line rated for 40 VA, with an inrush current of 40 A that must be considered when sizing the control transformer. Once energized, the drive responds to speed commands up to 400 Hz, and the internal regulator maintains velocity across a broad 1:5000 ratio, allowing slow index moves and rapid traverses from the same axis. A regenerative resistor is not built in, so external braking hardware is required for high-inertia decelerations. The ready output contact is also omitted, so machine controllers must monitor the drive through alternative I/O. A 30 A fast-acting fuse is required on the incoming main circuit to protect against short-circuit faults.

Power for the output bridge is drawn from a three-phase 200–230 VAC mains source. At switch-on, the drive draws a maximum surge of 23 A, so line contactors and circuit breakers must be sized accordingly. The aluminum chassis weighs 1.5 kg, simplifying panel layouts where multiple amplifiers share a compact enclosure. The amplifier can operate at temperatures from 0 to 55 °C and can be stored at temperatures between -20 and +65 °C. It also tolerates vibration up to 2 G. The unit continues to function in humid production areas, provided that the relative humidity does not exceed 90% RH without condensation.
