Mains Phase Loss
• speed controller incorrectly supplied or
fuses blown
• transient fault on one phase
• use on a single phase supply of an
ATV58•U72M2, U90M2 or a D12M2
(3-phase)
• check the power connection and the fuses
•reset
• configure the "In Phase Loss" (code
IPL) fault to "No", in the FAULT menu
