1. Product Description
Bosch Rexroth servo drives are high-performance electronic controllers designed to precisely control the speed, position, and torque of servomotors. They are a core component in motion control systems, converting control signals from a PLC or motion controller into the electrical power required to drive the motor accurately. Rexroth offers various series, known for their robustness, integration capabilities, and advanced control features. Key series include:
IndraDrive: A highly integrated drive concept combining motor, gear unit (optional), and drive electronics in a single housing, simplifying installation and wiring.
IndraDrive Mi: A modular version of IndraDrive, offering flexibility in motor and gear unit combinations.
Modular Servo Drives: Standalone drive units that can be flexibly combined with different motors.
These drives support various feedback technologies (e.g., absolute encoders, incremental encoders) and communication protocols (e.g., EtherCAT, Profinet, CANopen).
2. Product Parameters (Typical Range - Varies by Model)
Power Output: Ranges from a few hundred watts to tens of kilowatts (e.g., 0.5 kW to 75 kW or more).
Supply Voltage: Typically 230V AC, 400V AC, or 690V AC, single or three-phase.
Control Modes: Position control, speed control, torque control.
Communication Interfaces: EtherCAT, Profinet, CANopen, etc.
Feedback Interface: Supports various encoder types (e.g., EnDat, HIPERFACE DSL, Tamagawa).
Protection Class: Usually IP20 for the drive unit.
Mounting: Often DIN rail mountable.
Cooling: Forced air cooling via integrated fan.
Control Features: Field-oriented control (FOC), sensorless control options, advanced motion profiles, synchronization functions.
Software: Configured and programmed using Rexroth’s IndraWorks development environment and Indrawin software.
(Note: Specific parameters like current rating, voltage range, and power output must be checked against the datasheet of the exact model required for a specific application.)
3. Product Advantages
High Precision and Dynamics: Enable very accurate positioning and fast acceleration/deceleration, crucial for high-performance applications.
Robustness and Reliability: Designed for industrial environments, often with wide temperature ranges and protection against vibrations and electrical noise.
Integration: Especially the IndraDrive series offers seamless integration with Rexroth motors and PLCs (e.g., IndraLogic), reducing wiring complexity and installation time.
Flexibility: Available in various forms (integrated, modular) and support different motor sizes and types.
Advanced Control Algorithms: Feature sophisticated control techniques for optimal motor performance and smooth operation.
Diagnostic Capabilities: Provide detailed diagnostic information via communication interfaces, aiding in troubleshooting and maintenance.
Energy Efficiency: Modern designs often incorporate features to optimize energy consumption.
4. Precautions
Electrical Safety: Servo drives operate at high voltages and currents. Strict adherence to electrical safety standards and procedures is mandatory during installation, wiring, and maintenance. Disconnect power before accessing the terminals.
Proper Grounding: Ensure correct and secure grounding to prevent electrical hazards and reduce noise interference.
Correct Wiring: Follow the detailed wiring diagrams provided in the specific drive’s manual. Incorrect wiring can damage the drive, motor, or connected equipment.
Thermal Management: Ensure adequate ventilation and do not block the cooling fan. Operate within the specified ambient temperature range. Monitor temperature indicators if available.
Parameter Configuration: Incorrect parameter settings can lead to unstable operation, reduced performance, or damage. Use the recommended configuration tools (Indrawin) and consult manuals or technical support if unsure.
Motor Matching: Use a motor that is compatible with the drive’s power output, voltage, and control capabilities. Check the datasheets carefully.
Software Updates: Be cautious with firmware/software updates; follow the manufacturer’s instructions precisely to avoid bricking the device.
EMC Compliance: Install the drive and related cabling according to EMC (Electromagnetic Compatibility) guidelines to avoid interference with other equipment.
