- Heat Dissipation System: Consists of an aluminum heat sink and forced air cooling (built-in fan) to ensure stable operation in high-temperature environments.
- Status Indicator Lights: LED lights display power status, operation status, and fault codes (e.g., overcurrent, overvoltage).
- Housing: Made of metal material, providing EMI shielding and mechanical protection.
Key Features and Advantages
-
High-Precision Motion Control
- Nanoscale interpolation function, suitable for precision machining (e.g., laser cutting, semiconductor packaging).
- Adaptive vibration suppression algorithm, reducing the impact of mechanical resonance on positioning accuracy.
-
Intelligent Commissioning and Diagnostics
- Automatically optimizes servo parameters (e.g., rigidity, bandwidth) through the GE Motion Builder software.
- Real-time monitoring of current, temperature, and load rate to provide early warnings for potential faults.
-
Seamless System Integration
- Natively supports the EtherCAT high-speed bus, enabling multi-axis synchronous control (cycle time ≤1ms).
- Optional built-in PLC function for executing simple logic tasks (e.g., cam curve planning).
-
Industrial-Grade Reliability
- Overload capacity of 150% (sustained for 3 seconds) to handle instantaneous load impacts.
- Complies with the IEC 61800-3 standard, offering strong electromagnetic interference (EMI) resistance.
Application Fields
The CACR-SR03BE12G-E is mainly used in the following scenarios:
- Machine Tool Industry: Drive for CNC machine tool feed axes (e.g., X/Y/Z axes of milling machines).
- Industrial Robots: Servo control for joints of 6-axis robots.
- Packaging Equipment: Synchronous positioning control for high-speed labeling machines.
- Electronic Manufacturing: Precision pick-and-place of components in SMT placement machines.
Typical Application Case: In an automated packaging line, the CACR-SR03BE12G-E drives the GE AFM300 servo motor, and synchronizes with the upper-level PLC via EtherCAT to achieve high-speed and precise labeling at 120 times per minute.
