Product Overview

The Lexium 17D HP series is a high-performance, single-axis motion control system comprising a three-phase brushless servo amplifier, power supply, and digital controller in a single enclosure. It is designed to drive Lexium BPH series brushless servo motors. The system features advanced digital control, including a field-oriented current controller and a programmable PI-type speed controller.

Safety Information

DANGER: Electric shock hazards exist. Always keep covers closed during operation. Never disconnect electrical connections while power is applied. Wait at least five minutes after disconnecting power before touching energized sections, and ensure DC link voltage has fallen below 40V. Lethal voltages up to 900V may be present.

WARNING: The front panel acts as a heat sink and can exceed 80°C. Ensure proper ventilation and wait for it to cool below 40°C before touching. Separate overcurrent, overload, and overheating protection must be provided in accordance with local electrical codes.

Installation and Wiring

The drive must be mounted in a closed, vented switchgear cabinet free of conductive or corrosive contaminants. Ensure adequate airflow. Proper grounding of the drive mounting plate and motor housing is mandatory. Route power and control cables separately with at least 20 cm of separation. The system requires an external mains choke and appropriate fusing.

System Operation

The drive is commissioned using the UniLink software via an RS-232 connection. The system includes a restart lock (-AS-) for personnel safety, which must be wired according to EN60204, EN292, and EN 954-1 standards. The front panel features a three-character LED display for status, warning, and error codes.

Troubleshooting

The drive provides diagnostic information through warning and error codes on the LED display. Fatal faults disable the drive and open the fault relay. Common issues such as motor oscillation or poor performance can often be resolved by adjusting Kp and Tn parameters in the speed controller via the UniLink software.
