Description
Sets the output open-phase detec-
tion time in units of seconds.
If "0" is set, the output open-phase
detection function will be disabled.
Recommended setting: 0.2 (s)
0: Disable Enter command reception
during operations
1: Always enable Enter command
reception

This function automatically reduces
the carrier frequency to 2.5 kHz if
the output frequency is 5 kHz or
less, and the output current is 110%
or greater than the rated Inverter
current. Normally this setting is not
necessary. This function improves
the overload capacity at low fre-
quencies.
0: Disables low-speed carrier fre-
quency reduction.
1: Enables low-speed carrier fre-
quency reduction.
Note Normally, it is not necessary
to change the default setting.
Note This function is enabled if
n080 (carrier frequency) is set
to 2, 3, or 4.
