Product Description:

The TS1AA2AA servo amplifier is produced by Sanyo Denki for the BL Super Servo Amplifiers series. Designed as the power interface between a motion controller and a brushless servo motor, it converts low-level command signals into regulated phase current and voltage. By coordinating current vectors with rotor position, the module delivers the accurate speed and torque required by factory equipment such as pick-and-place heads and indexing tables. This control helps automated machinery perform repeatable positioning and motion cycles.

The amplifier has a continuous current capacity of 25 A, which indicates the current that the power transistors can deliver to the motor windings. The power stage is supplied by a 140 VDC main bus that may vary by ±10%, providing sufficient voltage for motor operation and rapid deceleration. Control electronics are powered by a separate 24 VDC supply, so digital logic and fault monitoring can remain active when the main power bus is off. Available motion references support pulse-train, speed, or torque control, allowing the amplifier to operate positioning, velocity-regulated, or torque-regulated axes. Reliable operation is maintained within an ambient temperature range of 0 to 55 °C through internal thermal management.

The drive uses an incremental encoder for feedback, allowing high-resolution quadrature pulses to close the servo loop. Command conductors terminate on an analog or pulse interface, which accepts either ±10 V analog speed references or differential pulse commands from a PLC. The aluminum housing weighs 0.45 kg, simplifying wall or rail mounting in compact control cabinets. Operation is permitted at a maximum relative humidity of 90% (noncondensing), and condensation must be prevented to protect the internal circuit boards. The amplifier does not include a gear reducer or tachometer generator. As a result, speed estimation relies on encoder feedback and software filtering rather than a separate tachometer signal.
