Product Description:
The TS1A02AA is a servo amplifier manufactured by Sanyo Denki as part of the BL Super Servo Amplifiers series. It converts logic-level commands and power from a regulated DC bus into three-phase drive currents, allowing a brushless motor to follow precise motion profiles. In industrial automation, the unit sits between a motion controller and the motor, modulating power to produce repeatable speed, torque, or position responses for pick-and-place heads, indexing tables, and similar equipment. This arrangement allows the motion controller to issue low-power commands while the amplifier supplies the current required by the motor.
The amplifier can deliver up to 20 A of continuous output current, providing capacity for mid-frame servomotors that experience cyclical load peaks. Its power section operates from a 140 VDC main bus, allowing the drive to be integrated into DC-link cabinets instead of relying on a line-commutated rectifier. The control electronics use a separate 24 VDC supply, which helps prevent switching noise from coupling into sensor inputs. Command data reaches the unit through an analog or pulse interface, so it can accept either ±10 V velocity references or high-frequency step-and-direction pulse trains from a position controller. The unit supports pulse-train, speed, or torque regulation modes, allowing the application to perform precise position moves, regulate velocity, or apply closed-loop torque limits without external hardware changes.
The housing weighs 0.45 kg, reducing the load on panel structures where multiple axes share limited installation space. Operation is permitted at relative humidity levels up to 90% noncondensing, which suits factory environments that maintain adequate vapor control. The operating temperature range begins at 0 °C and reaches a maximum of 55 °C, allowing the amplifier to run in cabinets that use forced-air cooling without active refrigeration. The unit does not include a gear stage because it functions strictly as an electrical amplifier rather than a mechanical drivetrain component. Tachometer-generator feedback is also absent, so compatible motor feedback and motion-control signals must be provided through the connected system. Adequate cabinet airflow and spacing remain necessary to prevent heat from accumulating around the housing during continuous operation.
