Internal Product Review
The QS1A01AAA045A3PAR is a Sanyo Denki servo amplifier that pairs an IGBT PWM sinusoidal drive with Speed/Torque/Position control for refined motion performance. The amplifier stands out in automation service with 1φ/3φ AC200V main circuit input and a 1:5000 speed control range that supports precise tuning across varied loads. A 10 ms dynamic brake delay is an especially strong specification for responsive machine protection.

Product Description:
The QS1A01AAA045A3PAR is a servo amplifier manufactured by Sanyo Denki as part of the Q SANMOTION Servo Amplifiers series. It conditions line power and executes closed-loop control so a connected servo motor can follow commanded speed, torque, or position profiles with high accuracy in industrial automation systems. All electronics are mounted on a built-in tray-type power supply structure, keeping the cabling within one enclosure.
The control section accepts a single-phase input of 1φ AC200V and limits the corresponding inrush current to 40 A. Internally, an IGBT PWM sinusoidal drive topology provides a bandwidth of 600 Hz, allowing rapid current regulation around the motor. Command resolution is supported by a speed control range of 1:5000, while separate 10 kΩ input impedances are assigned to the speed and torque reference channels to minimize loading on upstream motion controllers. The amplifier offers three selectable control functions: speed, torque, and position. This selection allows one device to accommodate several types of motion tasks without requiring separate control hardware. Transient energy returned from decelerating loads is absorbed by a built-in regeneration resistor rated at 100 Ω. Any remaining kinetic energy is diverted to a dynamic brake circuit that reacts after a 10 ms delay and can dissipate 360 J per event.
Main power can be supplied from either single-phase or three-phase sources at 1φ/3φ AC200V, and the line inrush current on this path is limited to 18 A. During operation, leakage current to the motor frame is limited to 0.5 mA, supporting compliance with safety standards that restrict touch current. The unit has a mass of 1.25 kg, which simplifies installation on panel rails or within compact machine modules without additional support hardware. Its compact enclosure also leaves more panel space available for neighboring control and power components.
