What we check
We check the motor, supply, load, braking and protocol before selecting the KV4500.
The official KV4500 manual lists 0.75–2.2 kW 220 V-class and 0.75–7.5 kW 380 V-class variants
the public product page states a wider 0.4–2.2 kW / 0.4–15 kW range, so this record uses the narrower manual-listed variants pending manufacturer reconciliation
