Professional FAQ

Q1: What fieldbus option is best for multi-brand systems?
A1: PROFINET or EtherNet/IP works best for mixed-control systems, giving smooth data exchange.

Q2: Does this drive handle sudden load changes?
A2: Yes. The HD overload level allows short spikes without shutdown, useful for compressors and conveyors.

Q3: What should I check before replacing an old inverter?
A3: Confirm input voltage, motor kW, and terminal type. Also check the braking and communication needs.

Q4: How do I prevent noise issues in long cable runs?
A4: Use shielded motor cables and keep power and signal cables separated. Grounding the shield also helps.

Q5: Can this drive run at low speed for long periods?
A5: Yes, but ensure airflow is not blocked. Low-speed running may require a fan or derating in hot areas.
