Note
The rated power of AC drives in the following tables is measured under the following
conditions:
● For three‑phase 380 V to 480 V models, the input voltage is 440 VAC.
● For three‑phase 200 V to 240 V models, the input voltage is 220 VAC.
● For single‑phase 200 V to 240 V models, the input voltage is 220 VAC.
