Product Description:

The PY0A100E0XXXP00 servo amplifier is manufactured by Sanyo Denki as part of the PY Super BL Servo Amplifiers series. This panel-mounted module conditions DC power from its internal tray-type supply and converts it into controlled AC power for Super BL servomotors, handling speed regulation and regenerative energy so the motion axis can accelerate, decelerate, and hold its position precisely in automated machinery. A built-in dynamic brake absorbs kinetic energy during deceleration, while an integrated cooling fan maintains the device’s normal operating temperature inside electrical enclosures.

Its servo-loop bandwidth is rated at 400 Hz, allowing rapid correction of speed errors when the drive receives new commands. The amplifier can regulate motor speed over a 1:5000 velocity control range, so the same axis can move slowly for positioning and quickly for traverse without requiring hardware reconfiguration. At power-up, the main circuit experiences an inrush current of 20 A, so upstream protection components must tolerate this brief surge. When a stop signal is issued, the embedded brake circuit engages after 24.0 ms, bringing the motor to rest and directing energy into the factory-installed resistor. This resistor supports 90 W of continuous dissipation during repetitive deceleration cycles.

The regenerative braking element has a resistance of 10 Ω, which limits the current flowing during braking events. The amplifier body weighs 6.0 kg, so cabinet shelving must be able to support this load. Air enters through the fan and exits through the heat sink, and a clearance of 50 mm above the unit is required to keep the airflow unobstructed. All conductors terminate under M4 screws, and each clamp should be tightened to 1.18 N·m to prevent thermal loosening. Diagnostic pins provide a current-monitor signal of 2.0 V ± 20% and a velocity-monitor signal of 2.0 V ± 10%, enabling drive status checks without removing the enclosure covers.
