
Set H19 value to 1

Output phase loss: Inverter output is shut off at the event of one or more output phase
loss among U, V and W.

Set H19 value to 2

Input phase loss: Inverter output is shut off at the event of one or more input phase loss
among R, S and T. If there is no input phase loss, output is shut off when it is time to replace
DC link capacitor.

Set H19 value to 3

Input/output phase loss: Inverter output is shut off at the event of one or more input or
output phases loss among R, S and T or U, V and W If there is no input or output phase loss,
output is shut off when it is time to replace DC link capacitor.
Caution:
Set H33- [Motor rated current] correctly. If the actual motor rated current and the value of H33
are different, output phase loss protection function could not be activated.
