Product Description:

The QS1L01AA03101P00 is a servo amplifier produced by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. It conditions mains power and controller commands so that a matched rotary servomotor receives precise current, speed, or position references. In industrial automation, this unit sits between a motion controller and the actuator, converting control-level instructions into three-phase power that drives high-speed rotary axes with tight torque regulation. With its standard interface, the module integrates into the position loops of assembly robots, packaging machines, and semiconductor tools where repeatable motion is essential.

The drive stage accepts 200 V AC three-phase power through the main circuit, while a separate single-phase feed supplies the control board. The amplifier can deliver a continuous output of 15 A, which is the maximum line-to-line current the connected motor can receive without derating. Its switching section uses an IGBT PWM sinusoidal drive topology to lower acoustic noise and minimize motor heating. A three-phase output is modulated through a position-control interface that uses the standard I/F arrangement. Energy created during rapid deceleration is handled internally by a built-in dynamic brake and a regeneration circuit, removing the need for external resistors.

Servo response is tuned with a frequency bandwidth of 600 Hz when the load inertia equals the motor inertia, allowing tight tracking of rapid setpoint changes. Speed control spans a ratio of 1:5000, so low-speed creep and full-rated velocity are both reachable without feedback loss. Position feedback is provided by a wire-saving incremental encoder with 2000 P/R, reducing cabling while maintaining fine resolution. The housing weighs only 1.25 kg, permitting compact panel layouts. The built-in electronics are optimized for rotary motors used in indexing tables and pick-and-place heads.
