Product Description:

The PY2A030A22M1P01 servo amplifier is produced by Sanyo Denki within the PY Super BL Servo Amplifiers series. It conditions command signals from a motion controller and delivers regulated current to a matched brushless servo motor, allowing automated conveyors, indexers, and pick-and-place modules to maintain precise velocity profiles. Designed for enclosure mounting, the unit incorporates monitoring points for speed and current feedback and includes an internal dynamic-brake circuit that shortens motor stopping time during emergency deceleration.

The drive uses forced-air cooling, so adequate cabinet airflow must be maintained to remove heat from the semiconductors. During power-up, the main circuit experiences an inrush current of 23 A, while the separate control circuit draws an initial surge of 40 A; input protection must accommodate both values. Continuous electronics power is 40 VA, and velocity commands are accepted through a 10 kΩ input whose monitor output reproduces the reference at 0.5 V ± 20% for oscilloscope measurements. The frequency response reaches 400 Hz, supporting high-bandwidth speed loops during rapid direction changes. The velocity control range is 1:5000, enabling slow creep feed as well as rated-speed operation without gain adjustments.

A built-in dynamic brake can absorb up to 360 J of kinetic energy per stop and engages after a delay of 10 ms, providing fast shaft arrest without external braking hardware. The unit has no regeneration resistor, so the application must remain within the stated braking duty when excess kinetic energy is absorbed. Its mass is 2.0 kg, which eases installation on swing-out panels and minimizes the load placed on the mounting surface. Current feedback is available through a monitor point rated at 0.5 V ± 20%, allowing users to confirm that the motor phase current follows the commanded profile during operation.
