0000h PA17 Function selection A-5
The [Pr. PA17 SEMI-F47 function selection] and [Pr.
PA18 SEMI-F47 function - Instantaneous power failure
detection time] settings of the converter unit must be
the same as [Pr. PA20 SEMI-F47 function selection]
and [Pr. PF25 SEMI-F47 function - Instantaneous
power failure detection time] settings of the drive unit.
_ _ _ x:
[AL. 10 Undervoltage] detection method selection
Set this parameter when [AL. 10] occurs due to
distorted power supply voltage waveform.
0: [AL. 10] not occurrence
1: [AL. 10] occurrence

Selecting "1" enables to avoid triggering [AL. 10
Undervoltage] using the electrical energy charged in
the capacitor in case that an instantaneous power
failure occurs during operation. In [Pr. PA18 SEMI-F47
function - Instantaneous power failure detection time],
set the time until the occurrence of [AL. 10
Undervoltage]. 0h

0000h PA18 SEMI-F47 function - Instanta-neous power failure
detection time
The [Pr. PA17 SEMI-F47 function selection] and [Pr.
PA18 SEMI-F47 function - Instantaneous power failure
detection time] settings of the converter unit must be
the same as [Pr. PA20 SEMI-F47 function selection]
and [Pr. PF25 SEMI-F47 function - Instantaneous
power failure detection time] settings of the drive unit.
Set the time until the occurrence of [AL. 10
Undervoltage].
To disable the parameter setting value, select
"Disabled (_ _ 0 _)" of "SEMI-F47 function selection" in
[Pr. PA17].
