Product Description:
The QS1A05AN0KEB2A04 servo amplifier is produced by Sanyo Denki as part of the Q SANMOTION Servo Amplifiers series. Designed to drive brushless servomotors in industrial automation, the unit supports coordinated speed, torque, and position control, allowing machine axes to track commands from a motion controller. Its IGBT-based pulse-width modulation topology converts the incoming AC supply into a sinusoidal, modulated output that follows precise command references. This operating method allows the amplifier to regulate motor current as axis speed and load conditions change during automated production cycles.
To accommodate separate power and logic feeds, the control circuit accepts an AC 200–230 V, single-phase, 50/60 Hz supply, while the main circuit can be connected to a single-phase or three-phase source with the same voltage and frequency rating. An IGBT pulse-width modulation bridge drives the motor and achieves a closed-loop bandwidth of 600 Hz when the load and motor inertias match. Velocity is commanded with a differential DC ±2.0 V signal, and torque references use the same nominal input level. The current-limit input also operates at DC ±2.0 V and constrains the phase current within ±15 percent. Regenerative energy is dissipated through a built-in resistor with a resistance of 17 Ω. A dynamic brake activates after a delay of 10 ms and can absorb up to 1800 J during rapid stops. These analog inputs provide separate command paths for speed, torque, and current limiting without requiring different external signal levels.
Pulse-train control accepts a maximum rate of 5 million pulses per second, allowing fine position increments while the motor operates at full speed. The speed loop covers a ratio of 1:5000, supporting both low-speed travel and high-speed movement with one tuning profile. Earth leakage remains below 1.5 mA during operation. The amplifier can be stored within a temperature range of -20 to +65 °C without damage. Its position, speed, and torque interfaces support motion tasks in packaging systems, semiconductor equipment, and small assembly machines. The separate control and main circuit connections allow the logic section and motor power stage to receive power through distinct wiring paths.
