Product Description:
The QS1A01AA0H8A3P1T is a servo amplifier from the Q SANMOTION Servo Amplifiers series manufactured by Sanyo Denki. As a position-control device, it supplies regulated power to a rotary motor and closes the motion loop through an absolute feedback channel, allowing compact machines to execute precise point-to-point movements. In automated cells, it pairs with wire-saving absolute sensors to reduce cabling while retaining multi-turn position data, making it suitable for axis drives that require rapid indexing and repeatable positioning.
This amplifier can deliver a continuous output current of 15 A, which is switched by an IGBT PWM sinusoidal drive system to minimize ripple at the motor terminals. Its velocity and torque control system has a frequency response of 600 Hz, allowing the unit to track rapid command changes. The built-in dynamic brake responds within 10 ms when braking is required. The braking circuit can absorb up to 360 J of regenerated energy before additional energy must be routed through an external resistor. Leakage to the protective earth conductor is limited to 0.5 mA, helping restrict unwanted current flow through grounded components. Velocity regulation covers a speed control range of 1:5000, supporting both slow movement and full-speed travel from the same axis.
The housing weighs 1.2 kg, which simplifies installation on moving carriages or inside lightweight control panels. Shaft position is measured with a 17-bit single-turn resolution, while an additional 16-bit multi-turn counter records complete revolutions for long-stroke applications. Position data is exchanged over a two-wire optical link operating at 2.5 Mbit/s; the link uses a wire-saving absolute sensor format that reduces the number of required encoder conductors. Regenerated power is routed through an external 100 Ω resistor, which protects the DC bus during deceleration. The optical sensor format also provides noise resistance in cabinets containing motors, switching devices, and other sources of electrical interference.
