Frequently Asked Questions
What type of command interface does the DKR04.1-W300N-BA03-01-FW support?
It uses an analog interface, which simplifies integration with traditional control systems but limits digital networking flexibility. This makes it suitable for retrofitting or hybrid automation environments.
What is the practical impact of its 212 A peak current capability?
This enables short bursts of high torque for acceleration or overcoming load spikes. Applications like heavy machining or press drives benefit from this reserve power.
Can the DKR04.1-W300N-BA03-01-FW operate in high-altitude locations?
It supports up to 1000 m without derating, but higher elevations reduce cooling efficiency. Additional considerations like forced cabinet ventilation or derated operation may be necessary above this altitude.
What happens if the unit is operated outside its 5–45 °C temperature range?
Continuous operation outside this range risks thermal stress, component degradation, or system faults. In high-heat areas, air conditioning or enhanced cooling may be required.
Why does the DKR04.1-W300N-BA03-01-FW weigh 150 kg, and what does that imply for handling?
The weight reflects its power electronics and cooling assembly, requiring lifting equipment for safe installation. Cabinet structures must be reinforced to support its mass.
