04: Frequency range for bypass
Interface
Setting
Parameter 2:
Set the acceptable low frequency for bypass.
50 Hz system: Setting range is from 46.0Hz to 49.0Hz.
60 Hz system: Setting range is from 56.0Hz to 59.0Hz. The default
value is 46.0Hz/56.0Hz.
Parameter 3:
Set the acceptable high frequency for bypass.
50 Hz: Setting range is from 51.0Hz to 54.0 Hz.
60 Hz: Setting range is from 61.0Hz to 64.0Hz.
The default value is 54.0Hz/64.0Hz.
05: ECO mode enable/disable
Interface
Setting
Parameter 3
: Enable or disable ECO function. You may choose fol-
lowing two options:
DIS
: disable ECO function
ENA
: enable ECO function
If ECO function is disabled, voltage range and frequency range for
ECO mode still can be set, but it is meaningless unless the ECO func-
tion is enabled.
06: Voltage range for ECO mode
Interface
Setting
Parameter 2:
Low voltage point in ECO mode. The setting range is
from -5% to -10% of the nominal voltage.
Parameter 3:
High voltage point in ECO mode. The setting range is
from +5% to +10% of the nominal voltage.
07: Frequency range for ECO mode
Interface
Setting
Parameter 2:
Set low voltage point for ECO mode.
50 Hz system: Setting range is from 46.0Hz to 48.0Hz.
60 Hz system: Setting range is from 56.0Hz to 58.0Hz. The default
value is 48.0Hz/58.0Hz.
Parameter 3
: Set high voltage point for ECO mode.
50 Hz: Setting range is from 52.0Hz to 54.0 Hz.
60 Hz: Setting range is from 62.0Hz to 64.0Hz.
The default value is 52.0Hz/62.0Hz.
