Servo-variateur multi-axes ACOPOS B&R 8V1016.00-2

Product Overview

The 8V1016.00-2 (8V1016.00-2) is a compact and highly efficient servo drive from the B&R ACOPOS series, designed to provide high-precision motion control for small-scale industrial applications. Engineered for flexibility, this drive supports a wide mains input voltage range from 230 VAC to 480 VAC, making it a versatile choice for global power standards. In sectors such as pick-and-place robotics, labeling machinery, and precise pharmaceutical packaging, the 8V1016.00-2 delivers exceptional dynamic performance with an installed load of 2.1 kVA. By integrating 3 slots for plug-in modules, it allows for easy expansion of communication interfaces and encoder systems, ensuring that the drive can adapt to evolving automation requirements while maintaining a small footprint and reducing overall system complexity.

Technical Configuration

The 8V1016.00-2 is built on a high-performance power stage capable of switching frequencies up to 20 kHz. It features an integrated line filter compliant with EN 61800-3 Category C3, which effectively suppresses electromagnetic interference and ensures stable operation within industrial environments. The drive manages power efficiently, with a maximum inrush current of only 2 A and a power dissipation of 110 W at nominal load. For logic and control, the unit requires a 24 VDC input, consuming a maximum of 1.47 A plus the current required for a motor holding brake. The hardware supports a maximum motor line length of 15 meters and can output frequencies up to 598 Hz, providing the necessary bandwidth for high-speed brushless DC and synchronous AC motors.

Technical FAQs

How does the configurable switching frequency affect drive performance?

The 8V1016.00-2 allows for 5, 10, or 20 kHz switching. Higher frequencies (20 kHz) provide smoother motor motion and quieter operation but increase thermal dissipation. Lower frequencies (5 kHz) reduce heat loss in the drive but may increase audible noise and current ripple in the motor.

What is the significance of the "Switch-on interval" for this drive?

The switch-on interval must be greater than 10 seconds. This duration allows the internal inrush current limiting circuit to cool down and reset. Repeatedly cycling the mains power faster than every 10 seconds can lead to premature failure of the charging resistors or the internal relay.

Are external filters required for CE compliance?

Because the 8V1016.00-2 includes an integrated line filter according to EN 61800-3 Category C3, additional external filters are typically not required for standard industrial installations (Second Environment). However, for applications in residential areas (First Environment), additional filtering may be necessary.

Engineering & Installation Guide

• Thermal Management: Ensure the drive is mounted vertically in the control cabinet. With a power dissipation of 110 W, adequate airflow is mandatory. If multiple drives are mounted in a row, maintain the minimum specified side-to-side clearance to prevent thermal cascading, which can trigger the "overtemperature" fault.

• Motor Cable Shielding: To maintain EMI compliance and prevent signal interference, use only shielded motor cables with a maximum length of 15 meters. The shield must be connected to the drive’s ground plate using a 360-degree contact clamp. Avoid "pigtail" grounding, as it is ineffective at the high switching frequencies (10-20 kHz) used by the ACOPOS system.

• Braking Resistor Considerations: The 110 W dissipation rating is calculated without an external braking resistor. For applications involving high-inertia loads or frequent deceleration, an external braking resistor must be connected to manage regenerative energy and prevent "DC Bus Overvoltage" errors.
