Description
Rexroth SE311 Controller Module 0608830237 Product Introduction
This is the Bosch Rexroth Indramat series digital servo controller module, part number 0608830237, mainly used for servo motor drive control in CNC machine tools and other precision motion control applications.
1、 Core positioning
SE311: The digital servo controller module is the core control unit of the Indramat control system.
Brand: Bosch Rexroth, originating from Germany.
Series relationship: Within the same series, there are also models such as SE301 (0608830160), KE310 (0608830240), KE300 (0608830162), etc. The SE series is positioned as a servo controller, while the KE series is another variant of the controller.
Attention: SE311 is a controller module that needs to be combined with Rexroth servo drivers (such as HCS01, CSB01, etc.) and servo motors to form a complete servo motion control system. Do not confuse it with the driver.

2、 Working principle
SE311 receives position, speed, and torque commands from the upper system (CNC, PLC, etc.), processes them through internal digital control algorithms, and outputs control signals to the servo driver, which drives the servo motor to execute accurately. The module is equipped with a three loop control architecture consisting of a current loop, a speed loop, and a position loop, which supports functions such as electronic gears, feedforward control, and vibration suppression filtering to achieve high-precision motion control.
3、 Key technical parameters
Number of control axes: Single axis controller (each module controls one servo axis)
Control modes: position control, speed control, torque control
Instruction interface: digital input/output+analog input (depending on configuration)
Communication interface: Supports connection with Indramat servo drives via digital bus
Response speed: microsecond level instruction processing
Applicable motor: matched with Rexroth Indramat series synchronous servo motor
Installation method: Installation of guide rails or panels inside the control cabinet
Protection level: Used inside the control cabinet, in compliance with industrial environmental requirements
4、 Main features
High precision: Three loop digital control, high positioning accuracy, suitable for precision machining.
High response: microsecond level signal processing, coupled with Rexroth drivers, can achieve high dynamic response.
Strong load capacity: capable of driving high-power servo motors to meet high load requirements such as heavy cutting.
Easy to integrate: Fully compatible with drivers such as Rexroth HCS01 and CSB01, as well as Indramat motors, and compatible with CNC systems such as Siemens 840D and Fanuc.
High reliability: Industrial grade design, suitable for long-term continuous operation.
5、 Typical applications
CNC machine tools: feed axis and spindle control for milling machines, lathes, grinders, and machining centers
Metal Forming: Servo Control of Stamping and Bending Machines
Printing and packaging: high-speed color matching, feeding control
Other: Any industrial application that requires high-precision servo motion control
