Product Description:

The QS1A05AN0KEB2A05 is a single-axis servo amplifier manufactured by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. It receives low-level velocity or torque references from a motion controller and modulates three-phase output to a servomotor, allowing tight speed and position regulation in automated assembly, packaging, and inspection lines. Cabinet installation is supported by its compact frame and low leakage current, so the unit fits easily into dense control racks that require reliable, high-response motor operation.

A built-in regeneration resistor rated at 17 Ω dissipates excess kinetic energy, while the amplifier’s IGBT PWM sinusoidal drive topology minimizes current ripple during high-speed operation. Earth leakage current is limited to 1.5 mA, reducing the need for additional grounding hardware. For external current limiting, the drive accepts a differential command of ±2.0 VDC; the same voltage range is provided at the current monitor terminal to represent the actual phase output. Velocity loop gain remains stable up to 600 Hz, and braking torque becomes available within 10 ms after a stop command, allowing the dynamic brake circuit to absorb up to 1,800 J per event. Separate torque and speed command channels allow the host controller to switch operating modes without rewiring.

The speed loop spans a ratio of 1:5000, so the motor can maintain slow inspection feeds and accelerate to its rated speed without changing gear ratios. Incremental feedback is accepted through an open-collector interface that handles pulse rates up to 150 kHz, making the amplifier compatible with high-resolution encoders used in precision stages. Control inputs present a 10 kΩ load, allowing standard analog I/O cards to drive the amplifier without buffering. The enclosure has a mass of 2.2 kg, allowing the unit to be installed on lightweight panel structures without placing excessive load on the mounting surface.
