Product Description:
The QS1A01AT04501PWA is a servo amplifier produced by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. Positioned between a motion controller and a matched servo motor, it converts incoming AC power into controlled motor current while managing the internal braking circuits. Within an automation cabinet, the unit supplies regulated current, coordinates safe stopping, and receives high-speed position commands so that linear or rotary axes can reach commanded positions accurately. Its role in the motion system includes regulating motor torque and speed in response to signals from the connected controller.
A branch protection device rated at 10 A protects the input line feeding the amplifier’s 200 V AC power stage, which accepts industrial mains at 50/60 Hz. Upon initial energization, the control circuit produces an inrush current of 40 A (0-P), while the main circuit produces an inrush current of 18 A (0-P). The inrush-prevention circuit maintains a charging interval of 900 ms for a three-phase supply and 1,800 ms for a single-phase supply. Protective earth resistance must remain below 100 Ω, helping provide a low-resistance path for fault current. Touch leakage current is limited to 0.5 mA to support safe operation within the automation cabinet and meet the applicable electrical requirements.
The internal dynamic brake absorbs 360 J during each braking event and can operate again after 10 ms, supporting controlled deceleration during repetitive motion. Command inputs are processed at rates up to 5 Mpps, allowing the amplifier to receive high-resolution position commands from compatible CNC or FPGA controllers. The unit does not have a built-in cooling fan, so the enclosure temperature must remain below 55 °C to prevent excessive thermal loading. Relative humidity must remain below 90% RH, and the cabinet must provide suitable ventilation around the amplifier. The amplifier weighs 1.25 kg, allowing it to be mounted without adding substantial load to the supporting cabinet structure while accommodating the stated vibration allowances.
