Product Description:
The PY2A015A0 is a servo amplifier manufactured by Sanyo Denki within the PY Super BL Servo Amplifiers series. It converts incoming AC power into controlled, pulse-width-modulated current that drives matched brushless servomotors. This operation enables closed-loop positioning and velocity control in automated machinery such as pick-and-place robots, conveyors, and indexing tables.
An output capacity of 15 A allows the unit to supply continuous motor current while remaining within its thermal limits. The control electronics are energized from a single-phase 200 VAC feed, and an inrush current of 40 A occurs when the circuit initially charges its capacitors. Upstream protection devices must tolerate this brief inrush condition. During normal operation, the control stage draws only 40 VA, helping limit the load placed on the panel power supply. Frequency response extends to 400 Hz, which permits accurate tracking of high-speed command signals in servo loops. A built-in dynamic brake dissipates regenerated energy during emergency stops. The unit does not include an internal regenerative resistor, so an external braking option is required for repeated or continuous deceleration. The aluminum housing is 135 mm deep, allowing installation in shallow cabinets. An Rdy ready relay output supplies system status through contacts rated for 250 VAC at 2 A or 30 VDC at 2 A.
The power stage accepts a three-phase input of 200 VAC, and its inrush current peaks at 23 A. Line reactors or soft-start devices may be added when the available supply capacity is limited. Closed-loop speed regulation spans a 1:5000 velocity range, supporting slow positioning moves and rapid indexing cycles with the same motor. The amplifier has a mass of 1.5 kg, which reduces the load placed on the mounting surface. Its chassis stands 168 mm tall, allowing alignment with adjacent drive modules while preserving space for cable bends. The compact enclosure can be secured to a suitable backplate within the control cabinet, and its shallow profile helps conserve usable panel depth.
