Frequently Asked Questions
How does the DKR02.1-W200B-BA03-01-FW manage excess energy during braking cycles?
It uses an integrated bleeder resistor to dissipate regenerative energy as heat. This prevents overvoltage conditions in dynamic applications such as CNC spindles or presses.
Can analog interfaces limit system integration flexibility?
Analog control simplifies compatibility with older equipment but offers less precision than modern fieldbus systems. It’s most suitable where retrofit or straightforward control is needed.
Why does the unit weigh over 100 kg, and what does that imply for installation?
The weight reflects robust construction and large heat management components. Proper mounting and lifting equipment are necessary for safe handling.
How does the rated current of 200 A influence motor compatibility?
It supports high-capacity motors requiring significant continuous current. This makes it suitable for large-scale mechanical drives with demanding duty cycles.
How does running on 3×AC 400–480 V affect deployment?
It requires a compatible industrial power supply, common in Europe and North America. Voltage mismatches could damage the unit or reduce efficiency.
