Product Description:

The QS1A05AN0KEB2A01 servo amplifier is produced by Sanyo Denki and belongs to the Q SANMOTION Servo Amplifiers series. As a pulse-width-modulated power stage, it regulates current, speed, or position for a matched servo motor so closed-loop motion tasks in assembly lines and packaging equipment can be executed precisely. It is intended for panel-mounted motion systems that need compact drive hardware, consistent servo response, and direct coordination between the amplifier and the connected motor.

The control section uses an IGBT PWM sinusoidal drive topology, allowing carrier frequencies up to 600 Hz so voltage vectors can follow command changes with low harmonic distortion. This arrangement helps the output waveform remain smooth across changing load conditions. A built-in regeneration resistor of 17 Ω dissipates surplus kinetic energy during rapid deceleration, reducing the need for separate braking hardware. The amplifier can report instantaneous phase current through a monitor terminal that delivers 2.0 V at rated feedback, which supports quick signal verification. Under speed regulation, the hardware maintains a control ratio of 1:5000, enabling stable low-speed threading as well as high-speed indexing without changing gain settings.

For emergency stops, the amplifier integrates a dynamic brake rated for 1800 J, and its activation circuit closes within 10 ms to limit motor motion before servo feedback loses position accuracy. Operational data such as alarm codes and parameter numbers appear on a 5-digit 7-segment LED display. One digital and two analog monitor channels allow simultaneous observation of speed, load, and bus voltage, which makes local status checks easier. A built-in cooling fan draws air through the tray-type structure, helping maintain thermal stability within the compact 2.2 kg enclosure.
