Vacon NXI_xxxx 5 – Supply voltage 465-800 Vdc, Motor voltage 380—500 Vac
High overload =
Max current IS, 2 sec/20 sec, 150% overloadability, 1 min/10 min
Following continuous operation at rated output current, 150 % rated output
current (IH) for 1 min, followed by a period of load current less than rated
current, and of such duration that the r.m.s output current, over the duty cycle,
does not exceed rated output current (IH)
Low overload = Max current IS, 2 sec/20 sec, 110% overloadability, 1 min/10 min
Following continuous operation at rated output current, 110% rated output
current (IL) for 1 min, followed by a period of load current less than rated
current, and of such duration that the r.m.s output current, over the duty cycle,
does not exceed rated output current (IL)
Frames FR4…7 are available as IP21 and FR8 as IP 00
