Technical Specifications

Installation Guidelines

• Mounting: Install the drive in a clean, ventilated enclosure to prevent dust buildup and overheating.
• Grounding: Ensure a solid, low-impedance connection to the protective earth (PE) terminal to maximize the effectiveness of the integrated EMC filter.
• Shielding: Use shielded motor cables and route them separately from control and signal wiring to mitigate EMI.
• Environment: Ensure the ambient temperature remains within the manufacturer’s specified limits, as the Altivar 71 relies on internal cooling fans for thermal management.
• Configuration: Use the graphic terminal to perform the initial setup and "Auto-tuning" to optimize the drive performance for your specific motor.
