Subject: Re: [Emc-users] max motor size that a 8i20 can control
hey peter
I have just been looking at the manual for the 8i20 and it says 2200w 400v
motor power
Thats 400 V maximum DC bus power (you need 1.414 x motor AC voltage) so about
340 VDC for a 240VAC motor. A 416VAC motor needs about 588VDC
Is that correct? or is this for the dc power on the output of the drive
and maybe it takes 230v ac three phase line power in?
Yes Its the DC power
slightly confusing.
here in New Zealand all three phase power is 400v so it would be good for
have a drive that I can just plug in without using other transformers etc
regards
Andrew

hey gene
yes it weighs 15 kg
still thinking it would be good to use a 8i20 initial feedback is not
sounding too good:)

A 8I20 drive (or STMBL) would run that (6.5A cont is say 20 A peak) but
only at
about 1/2 speed because the 8I20 (and the STMBL) are 230V drives, that
really
needs a 460V drive.
