Product Description:

The QS1W05AM0XXXXC16 servo amplifier is manufactured by Sanyo Denki within the Q SANMOTION Servo Amplifiers series. It occupies the power-conversion layer of an automation chain, translating logic-level pulses into regulated drive current for a companion servomotor. By supervising regenerative energy and thermal load, the unit maintains the motion accuracy required for industrial positioning tasks.

Motion commands reach the amplifier over differential lines, and its speed, torque, and position control capability lets the host controller switch operating modes without rewiring. An internal bridge that uses sinusoidal IGBT PWM switching shapes the output waveform to minimize motor ripple. The control electronics draw power from a DC 5–24 V logic rail, which isolates them from the power stage. Incremental references are decoded at up to 5 million pulses per second for high-resolution positioning, while the main circuit operates with utility supply frequencies of 50/60 Hz ±3 Hz. A built-in fan forces airflow across the heat sink to keep semiconductor temperatures stable. Position inputs follow the RS-422 standard, and two-phase commands are accepted at 1.25 million pulses per second. Speed and torque commands enter through ±2.0 V analog channels.

Leakage current does not exceed 1.5 mA, helping limit current flow to the chassis. Ambient operation is permitted at temperatures up to 55 °C, although the limit decreases to 50 °C when the unit is mounted on its side. Open-collector sources can clock the pulse port at 150 kHz when transistor outputs are used. The torque limit has a fixed scale of 2 V per rated torque, allowing predictable mechanical load limiting. Regenerative energy is routed through the RB1 and RB2 terminals to an external resistor bank. The internal control map uses the same ±2.0 V range as the speed and torque command channels.
