Product Description:
The QS1L01AA45A3PAR servo amplifier is built by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. As a compact drive module, it supplies regulated power to AC servo motors and executes velocity and torque commands issued by a motion controller. Within automated assembly lines, packaging machines, and semiconductor tools, the amplifier maintains closed-loop motor control so that axes follow programmed trajectories with high accuracy.
Control power for the unit is derived from a single-phase AC source, which simplifies auxiliary wiring because only one phase and ground are needed for the logic supply. Motor current is synthesized by an IGBT PWM sinusoidal drive topology, giving low harmonic distortion and permitting fast loop updates. The amplifier achieves a frequency response of 600 Hz, allowing the position loop to react rapidly to command changes. It sustains a speed control span of 1:5000, so slow creep movements and high-speed indexing can be handled by the same hardware. The protective design limits residual chassis leakage to 0.5 mA, reducing the risk of electrical exposure. A five-digit, seven-segment LED panel provides parameter readouts, and the built-in dynamic brake works with the internal regeneration network. An external resistor can be added when high-inertia loads require extended braking duty. Tray-type construction, a fanless thermal path, and Class 3 D-type grounding complete the electrical arrangement.
The amplifier can operate at up to 90% RH without condensation, withstand mechanical shocks of 5 G, and endure continuous vibration levels of 0.5 G. Its weight of only 1.25 kg eases DIN-rail or tray mounting alongside other control equipment without placing a substantial load on the supporting structure. The grounding scheme isolates power noise from sensitive analog lines, helping preserve signal quality when the amplifier is installed near switching equipment. The absence of a cooling fan eliminates moving parts that could draw contaminants into the enclosure and allows heat to dissipate through the fanless thermal path.
