6.15.9 Undervoltage trip
: Undervoltage trip selection
• Function
This parameter is used for selecting the control mode when an undervoltage is detected. Trip infor-
mation is displayed as “ “.
(Disabled).......The inverter is stopped. However, it is not tripped (FL relay deactivated).
The inverter is stopped when the voltage does not exceed 70% or less of its
rating.
(Enabled) .......The inverter is stopped. It is also tripped (FL relay activated), only after detec-
tion of a voltage not exceeding 70% or less of its rating.
(Disabled).......Control is continued even at 60% of the rated voltage.
The inverter stop (FL relay deactivated), only after detection of a voltage not ex-
ceeding 45% of its rating.
An input AC reactor must be used. See 10.4.

6.15.10 4-20mA dc calibration
: Meter bias
• Function
Output signals from FM terminals are analog voltage signals. Their standard setting range is from 0
to 1mAdc or from 0 to 7.5Vdc.
These standard setting ranges can be switched to 0-20mAdc by changing the position of the required
jumper pin (JP302) in the inverter main unit. Calibration for 4-20mA dc output is possible by setting
this parameter.
Title Function Adjustment range Default setting
Meter bias 0 ∼ 50 (%) 0
Note: Use the jumper pin (JP302) to select FMC (0-20mA dc (4-20mA dc)) output.
