Rexroth R061001600 Digital Controller

Product Detailed Description

Rexroth Actuator Modules generally fall into several categories:

1. Electromechanical Cylinders (EMC): These replace traditional hydraulic or pneumatic cylinders with an electric servo motor driving a lead screw or ball screw. They offer high force, precision, and energy efficiency.

• High force density and stiffness.

• Precise positioning and repeatability.

• Energy-efficient operation (power-on-demand).

• Clean, quiet operation, eliminating the need for hydraulic power units or pneumatic air supply.

• Often come with integrated sensors for position feedback.

• Suitable for heavy-duty applications (e.g., EMC-HP High Power series).

• Function: Convert rotary motion from a servo motor into precise linear motion and force.

• Features:

2. Linear Axes / Linear Modules (e.g., Compact Modules, Small Modules, Linear Motor Modules): These are ready-to-install linear motion systems that combine a linear guide (e.g., ball rail system), a drive mechanism (e.g., ball screw, toothed belt, or linear motor), and often a motor mounting interface.

• Screw-driven (Ball Screw/Lead Screw): Offer high precision, rigidity, and force, suitable for precise positioning and pressing applications.

• Belt-driven: Provide high speed, long strokes, and good dynamics, suitable for rapid transfer and pick-and-place applications.

• Linear Motor Modules: Offer the highest dynamics, speed, and precision due to direct drive technology (no mechanical transmission), ideal for very fast and accurate positioning tasks.

• Compact and flat designs for easy integration into machines.

• Pre-assembled and tested for quick commissioning.

• Can be combined to form multi-axis systems.

• Function: Provide precise linear movement for handling, positioning, and assembly tasks.

• Features:

3. Rotary Actuators / Rotary Modules: These are integrated units designed for precise rotary motion, often incorporating a motor and gearing.

• High torque and precision.

• Compact form factors.

• Often feature large through-holes for cable passage.

• Function: Provide controlled angular movement for rotating, indexing, or orienting objects.

• Features:

Product Parameters (General Ranges, highly dependent on specific module type and size)

• Stroke Length (Linear Actuators): From a few millimeters to several meters (e.g., 50 mm to 5000 mm+).

• Force/Load Capacity (Linear Actuators): From a few kilograms to several tons (e.g., 10 kg to 200 kN).

• Speed (Linear Actuators): From a few mm/s up to 5 m/s or more (linear motor modules).

• Acceleration (Linear Actuators): Up to 250 m/s² (linear motor modules).

• Repeatability: Typically ±0.01 mm to ±0.001 mm (screw-driven and linear motor modules).

• Voltage: Typically 24 VDC for smaller modules, or connected to servo drives (e.g., IndraDrive) requiring 230/400/480 VAC.

• Motor Type: Often integrated permanent magnet synchronous motors (servo motors) or stepper motors.

• Interfaces: Mechanical (flange, direct coupling, belt side drive for motor), Electrical (motor power, encoder feedback), Communication (EtherCAT, PROFINET, SERCOS, etc., via associated drive).

• Protection Class: Varies depending on environment, typically IP40 to IP65.

• Operating Temperature: Typically 0 °C to +50 °C.

Product Advantages

• Integrated Solutions: "Plug & produce" approach simplifies design, assembly, and commissioning, reducing time-to-market.

• High Performance: Offers precise positioning, high dynamics, and excellent repeatability for demanding applications.

• Energy Efficiency: Electromechanical solutions consume power only when needed (power-on-demand), leading to significant energy savings compared to constantly running pneumatic or hydraulic systems.

• Clean and Quiet Operation: Eliminates the noise and fluid leakage associated with pneumatic/hydraulic systems.

• Scalability and Flexibility: Modular design allows for easy integration into multi-axis systems and adaptation to various application requirements.

• Low Maintenance: Components like ball rail systems and linear motors are often designed for long relubrication intervals or are maintenance-free.

• Industry 4.0 Readiness: Many modules are part of Rexroth's "Smart MechatroniX" portfolio, offering integrated sensors and connectivity for data acquisition and predictive maintenance.

• Reduced Total Cost of Ownership (TCO): Through energy savings, reduced maintenance, and faster commissioning.

Precautions

• Correct Sizing and Selection: Accurately determine load, speed, stroke, and precision requirements. Utilize Rexroth's selection and sizing tools (e.g., LinSelect) to choose the appropriate module. Incorrect sizing can lead to premature wear or insufficient performance.

• Proper Installation: Adhere strictly to Rexroth's installation manuals. Ensure proper mounting (e.g., on a flat, rigid surface), correct alignment, and secure fastening to avoid performance degradation or damage.

• Motor and Drive Integration: Ensure the selected actuator module is compatible with the chosen servo motor and drive system (e.g., Rexroth IndraDrive). Proper tuning of the servo drive is critical for optimal performance.

• Environmental Conditions: Operate within specified temperature, humidity, and vibration limits. Protect the module from excessive dust, chips, or corrosive substances, especially for modules without high IP ratings.

• Lubrication (for screw-driven/belt-driven): Follow recommended lubrication schedules and use specified lubricants to ensure long life and performance. Linear motor modules are typically maintenance-free regarding lubrication.

• Cable Management: Ensure proper routing and protection of power and encoder cables to prevent damage from bending, twisting, or abrasion, especially for moving cables.

• Safety Functions: When implementing safety functions (e.g., Safe Torque Off - STO), ensure they are correctly wired and configured according to safety standards (e.g., EN ISO 13849, IEC 62061).

• Initial Start-up: Perform careful initial checks and commissioning procedures, often guided by the drive's software, to confirm correct operation and parameter settings.
