A servo amplifier belongs to the electrical drive chain: it controls the power delivered to a servo motor, rather than providing the mechanical movement itself. The ASM SIPLACE 00321733 TDS120/25Y Y-Axis Servo Amplifier is identified by both its amplifier designation and Y-axis application.
The TDS120/25Y reference is an important part of the product identity. A servo amplifier should not be selected solely by axis name, since the drive model and machine configuration also determine whether a replacement is appropriate. Retaining the complete number helps distinguish this unit from other motion-control electronics.
