Product Description:
The TS1B02AA is a servo amplifier produced by Sanyo Denki for the BL Super Servo Amplifiers series. Acting as the drive interface between a motion controller and a DC brushless motor, it modulates current in real time so industrial axes can follow position, speed, or torque commands with minimal delay. By converting low-level reference signals into power-stage switching patterns, the unit helps packaging machines, pick-and-place modules, and general automation stations achieve tightly regulated motion profiles.
This model delivers a peak output capacity of 20 A, allowing the power stage to supply additional current to the motor windings during brief periods of high demand. The control electronics are energized from a separate DC 24 V rail, isolating logic and feedback processing from higher-energy switching noise. Command handling follows a pulse train, speed, or torque control system, so the amplifier can follow step-and-direction pulses, maintain velocity with an analog reference, or regulate shaft torque against load variations. Signal exchange is possible through a dual-mode analog or pulse interface that accepts ±10 V inputs or line-driver pulse streams for flexible integration with a PLC or motion card. Motor power is sourced from a dedicated DC 50 V supply, allowing the drive to operate in low-voltage DC bus architectures often found in compact multi-axis platforms.
The housing weighs 0.45 kg, reducing cabinet load and easing installation on DIN rails or backplates. Continuous operation is permitted at a relative humidity of up to 90% maximum, enabling use in humid production zones when condensation is prevented. The amplifier contains no gear reduction stage, so it does not introduce mechanical backlash into the control loop. The design also includes no tachometer generator, so speed feedback must come from an external encoder or resolver connected to the control system. This arrangement allows the motion controller to process feedback signals and issue the appropriate command to the amplifier without relying on an internal tachometer generator.
