Yokogawa DD servo kit, model SD1050A02-2SN, includes motor DM1050A0[USED]

Description

Yokogawa DYNASERV SD1050A02-2SN + DM1050A00 Direct Drive (DD) Servo Kit. This is an iconic high-torque, high-precision disc direct drive system from Yokogawa, commonly used in semiconductor exposure, LCD panel inspection, precision machine tool turntables, etc., where high positioning accuracy and response speed are required.
1. Model Decoding and Positioning
Driver: SD1050A02-2SN
SD1050A02: Special driver for DM1050A motor in DYNASERV series, 230VAC input, full digital closed-loop control;
2SN: Interface / specification suffix, representing standard communication / feedback configuration, compatible with absolute encoders, supports position / speed / torque three modes;
Category: DYNASERV DD Servo Actuator product line, supporting hot standby, complete fault protection and diagnosis.
Motor: DM1050A00
DM1050A: A series disc direct drive motor, without reduction gear, high torque density; 00 is the standard version (without brake / special sealing);
Core advantages: zero backlash, high rigidity, low inertia, fast response, eliminating errors and maintenance caused by gears / belts.
