Product Description:

The QS1L03AA07E01P00 servo amplifier is produced by Sanyo Denki as part of the Q SANMOTION Servo Amplifiers series. It drives matched servomotors in industrial automation equipment, receiving command signals from a motion controller and converting them into phased current that follows reference speed, torque, or position loops. The unit supports packaging stations, robotic axes, and surface-mount lines where accurate dynamic response and compact installation are required, consolidating power conversion, protection, and regenerative features inside a single enclosure.

The power stage delivers up to 30 A, so moderate-to-high-inertia loads can be accelerated without saturation. A three-phase input rated for 200 V supplies the internal bus, while the synthesized output bandwidth reaches 600 Hz to track high-frequency command changes. The pulse-direction port accepts streams up to 5 Mpps, letting indexers execute very short moves without losing resolution. Velocity regulation spans a ratio of 1:5000, giving fine control from a slow jog to full rated speed. Built-in speed, torque, and position control functions are complemented by a cooling fan that removes switching heat. An integral dynamic brake clamps motion during emergency stops, and regeneration circuitry directs excess energy to an onboard resistor instead of requiring external dump hardware.

The internal resistor presents a load of 50 Ω to limit DC-bus voltage rise when braking heavy axes. Drive waveforms are produced by an IGBT PWM sinusoidal drive system, which lowers torque ripple and acoustic noise. Mechanical integration is aided by compact dimensions of 168 × 160 × 70 mm, and the amplifier weighs 1.3 kg. A built-in tray-type power supply eliminates the need for separate converters. The enclosure accommodates the regeneration circuitry, cooling fan, and dynamic brake without requiring additional external modules.
