Description
B&R BV1045.00-2 Servo drive
Product Dimensions:
The B&R BV1045.00-2 is a high-performance servo drive module from the ACOPOSmulti series. It is designed to provide precise motion control within the B&R industrial automation ecosystem, specifically tailored for multi-axis applications where space-saving and energy efficiency are priorities.
Technical Specifications
The BV1045.00-2 is a double-axis module, meaning it can control two independent motors from a single unit.
| Parameter | Specification |
| Series | ACOPOSmulti |
| Module Type | Inverter Module (Double-axis) |
| Continuous Current | $2 \times 4.5\text{ A}$ |
| Peak Current | $2 \times 9\text{ A}$ |
| DC Bus Voltage | $800\text{ VDC}$ (Nominal) |
| Cooling Method | Wall mounting (Heat sink) |
| Communication | POWERLINK (Standard for ACOPOSmulti) |
| Safety Function | Integrated STO (Safe Torque Off) |
Key Product Advantages
-
Compact Footprint: By housing two inverters in a single module, it significantly reduces the required space in the control cabinet compared to two single-axis units.
-
Energy Efficiency: It utilizes a common DC bus system, allowing energy generated during braking in one axis to be shared with another axis that is accelerating.
-
High Precision: Integrated with B&R’s POWERLINK communication, it ensures microsecond-level synchronization for complex multi-axis movements.
-
Simplified Wiring: The module uses a refined mounting system that allows for quick installation and “cold plate” or wall-mount cooling options, reducing assembly time.
Safety & Precautions
Warning: Industrial servo drives involve high voltages and moving parts. Only qualified personnel should perform installation and maintenance.
-
DC Bus Discharge: After turning off the power, wait at least 5 minutes for the DC bus capacitors to discharge to safe levels before touching terminals.
-
Thermal Management: Ensure there is adequate airflow around the heat sink. Overheating can lead to premature aging or immediate shutdown.
-
Grounding: Proper earthing is mandatory to prevent electromagnetic interference (EMI) and to ensure operator safety.
-
Firmware Compatibility: Ensure the Automation Studio software version used matches the hardware revision to avoid communication errors.
Typical Applications
The BV1045.00-2 is commonly found in industries requiring high-speed, synchronized motion:
-
Packaging Machinery: Coordinating film feed and sealing jaws.
-
Printing Industry: Synchronizing multiple rollers to maintain web tension.
-
CNC Woodworking: Precise control of X-Y gantry movements.
-
Robotics: Controlling small-to-medium payload robotic arms or pick-and-place units.
