Electronic Thermal Warning Output –Please refer to page 3-39 for detailed information.
Zero speed detection Output – The inverter outputs the 0Hz speed detection signal
when the inverter output frequency falls below the threshold frequency specified in the
zero speed detection level (C063).
To use this function, assign parameter “21” to one of the intelligent output terminals
[11] to [12] (C021 to C022), or to the alarm relay output terminal (C026).
This function applies to the inverter output frequency when the V/F characteristic
curve selection is based on the constant torque (VC), reduced torque (VP), free-V/F,
sensorless vector control, or 0Hz range sensorless vector control.
Heat Sink Overheat Warning Output – The inverter monitors the temperature of its
heat sink, and outputs the heat sink overheat warning (OHF) signal when the
temperature exceeds the heat sink overheat warning level specified in parameter C064.
