Some questions about a servo motor driver input ratings
Now look carefully. Continous output power @ rated input current:
It says for 3x240VAC input voltage, that will have 4.6A rated input current, the output power is 1250W.

Let's calculate the output voltage: \$V=\dfrac{1250VA}{\sqrt{3}\cdot 6A}= 120V\$

It makes sense now, te input apparent power is 2kVA and the output power is 1.3kVA. But this driver can't provide output voltage 240VAC @ 6A. You'd need to contact the manufacturer for further explanations.

Anyway, what is the connected motor?




I'll explain later...
