Product Description:

The PY0A015A1N31P00 is a servo amplifier manufactured by Sanyo Denki within the PY Super BL Servo Amplifiers series. This power unit controls matched Super BL servo motors in positioning tables, pick-and-place modules, and similar motion axes where rapid response and repeatable velocity are required. By modulating the motor phase current, it closes the torque loop and supplies dynamic braking, allowing automated equipment to stop accurately and restart without drift.

The drive’s continuous output rating is 15 A, delivered from a single-phase 200 VAC mains section that includes an integral dynamic-brake circuit. A main supply demand of 0.3 kVA establishes the cabinet transformer and wiring requirements, while a separate control section draws 40 VA for logic and gate drive. Input surge is limited to 18 A on the power bus, but the control electronics can experience an inrush current of 40 A during precharging. The amplifier tracks command changes up to 400 Hz, giving it sufficient bandwidth to maintain a tight following error during high-speed indexing. Position feedback is accepted from an INC-E incremental encoder with 2000 P/R, so feedback resolution remains constant throughout operation.

The motion loop maintains linearity across a 1:5000 velocity range, enabling both slow homing moves and rapid transfers without retuning. During an emergency stop, the brake resistor absorbs 360 J, and the brake engages 6.5 ms after the stop command. Generated heat is limited to 19 W, supporting dense multi-axis mounting in a control panel. Earth leakage remains below 3.0 mA, which supports compatibility with common protective circuitry. All components are packaged in a housing that weighs 2.2 kg, so the unit can be panel-mounted without heavy mounting hardware. The interface operates in position-control mode for integration with a compatible host controller.
