LTi SO84.008 ServoOne Three-Phase Drive Controller BG2

The LTi SO84.008 belongs to the ServoOne series with a BG2 housing offering higher power density. Rated at 8A continuous and 16A peak, this air-cooled drive operates on 3x230V to 3x480V AC mains, making it suitable for more demanding single-axis applications where compactness remains important.

Key Specifications

• Continuous current: 8 A (at 400V, 8 kHz switching frequency)

• Peak current: 16 A (0-5 Hz, intermittent operation)

• Wider BG2 dimensions: width 90 mm, height 345 mm, depth 240 mm, weight 4.9 kg

• Integrated mains filter and brake chopper

• External braking resistor minimum: 90 Ω (for 400V mains)

• Switching frequencies up to 16 kHz (with derating)

Technical Data

Installation Notes

Install the BG2 unit with minimum clearances: 100 mm above and below (air cooling). Use shielded motor cables ≤10 m for full current rating. The larger housing provides improved heat dissipation. Always ground the PE conductor as per EN 61800-5-1. For EMC compliance, an external mains choke is recommended for industrial environments (environment class 3).

Commissioning and Operation

Commission with DriveManager 5. After applying 24V control supply, the 7-segment display shows "00" then "51". Load motor dataset or configure manually. Enable STO inputs (ISDSH, ENPO) and then the start command. The drive provides precise speed and torque control. The integrated MMC card slot allows parameter copying for series machines.

Typical Applications

The 8A rating suits motors up to approx. 2.2 kW (400V). Typical applications include small presses, winding machines, conveyor drives with higher inertia, and packaging equipment requiring rapid acceleration.

Standards

Complies with 2006/95/EC, 2004/108/EC, EN 61800-5-1, and EN 61800-3 (C2/C3). UL conditions: copper 75°C cables, 5kA short-circuit rating.

The LTi SO84.008 provides a reliable step up in power while maintaining the compact ServoOne architecture.
