Product Description:

The TS1A03AA is a DC-bus servo amplifier produced by Sanyo Denki for the BL Super Servo Amplifiers series. It is designed to supply controlled current to matched BL servo motors, allowing positioning, speed regulation, and torque control in automated machinery such as pick-and-place modules, feeders, and index tables. By converting the plant’s DC link and control references into phase-synchronized drive signals, the unit forms the power stage between a motion controller and the motor windings.

This amplifier can deliver up to 30 A of output, establishing the maximum continuous motor phase current available for acceleration or stall holding. Its power section operates from a DC 140 V main input, so it connects directly to rectified 100 to 120 VAC lines in compact control cabinets. The logic and interface circuits are energized separately through a DC 24 V control input, isolating the signal electronics from bus fluctuations. Three selectable operating modes—pulse train, speed, and torque—allow the host controller to choose between position pulses, analog velocity commands, or current references without hardware changes. Motion commands enter through a mixed analog and pulse interface, providing flexibility for PLC high-speed outputs or ±10 V analog cards through the same command interface.

A shaft sensor signal is accepted from an integrated incremental encoder, so high-resolution feedback is available without an external tachometer. The housing carries an IP43 rating and operates at ambient humidity levels up to 90% without condensation, limiting access by solid objects and water spray. The compact unit has a mass of only 0.65 kg and a depth of 75 mm, simplifying panel layout while leaving 90 mm of width and 120 mm of height for cable bends and airflow. Wiring is completed through an M4 ground terminal, and the design omits gearing and a tachometer generator to minimize moving parts while using the encoder for all dynamic feedback.
