Control Mode For Low Current - Toshiba TOSVERT VF-AS1 Instruction Manual

6.33.8 Control mode for low current

 : Low current detection hysteresis width
 : Low current trip selection
 : Low current detection current
 : Low current detection time
• Function
If the current is lower than  level and passes for a time longer than , the inverter trips.
Trip information is displayed as "."

=: No tripping (Failure signal FL deactivated).
A low current alarm can be put out by setting the output terminal function selection parameter.
=: The inverter will trip (the failure signal FL will be activated) if a current below the current set with
 flows for the period of time specified with .

When = (tripping), the inverter will trip if low current lasts for the period of time set with .
After tripping, the low current signal remains ON.
