Product Description:

The PY0A100E0XXYPH1 servo amplifier is manufactured by Sanyo Denki as a member of the PY Super BL Servo Amplifiers series. It conditions incoming AC power, regulates motor current, and monitors speed feedback so brushless servomotors can follow torque and velocity commands issued by a motion controller. With a mass of 6.0 kg, the unit installs easily in crowded control enclosures and supplies the dynamic braking functions required for rapid deceleration in automated machine tools and material-handling axes.

Main power reaches the drive on a three-phase 200-230 VAC bus at 50/60 Hz, while an auxiliary single-phase line feeds the control circuits. Returned kinetic energy is dissipated internally through a 90 W regeneration circuit, and a dedicated terminal allows an external 10 Ω resistor when higher absorption is needed. Inrush current peaks at 20 A, so upstream protection devices must tolerate that brief draw. Current limiting is commanded by an analog reference of ±2.0 VDC with a tolerance of ±10%, and the onboard monitor reproduces armature current at 2 V for diagnostic scopes. A closed-loop bandwidth of 400 Hz lets the amplifier react quickly to load changes, supporting precise contouring and tension control tasks.

The velocity control loop spans 1:5000, allowing stable rotation from creep speeds up to the motor’s rated maximum without mode switching. When a stop is requested, torque is applied almost immediately; the dynamic brake engages after only 24.0 ms, minimizing overrun on vertical or high-inertia axes. For applications with sizable inertia or frequent reversals, an external network can absorb up to 3000 W of regenerated power without stressing the amplifier. Continuous operation is permitted at ambient temperatures between 0 and 55 °C, and the unit may be stored at temperatures from -20 °C to 65 °C without performance loss.
