Functions
0-Hz Detection Signal
• This function outputs a detection signal when the Inverter's output frequency falls below the 0-Hz
detection value set in 0-Hz detection level C063.
• Enabled when "21" (ZS) is allocated to any of multi-function output terminals P1 to P5 (C021 to
C025) or the relay output terminal (C026).
When "VC", "special VP", "free V/F", "sensorless vector control", or "0-Hz sensorless vector
control" is selected as the control method, this function works for the Inverter's output frequency.
When the control method is "sensor vector control", this function works for the motor rotation
frequency.
Alarm Code Output (AC0 to AC3)
• This function outputs a 3-bit or 4-bit code signal to indicate the cause of an Inverter trip.
• If "01" (3-bit) or "02" (4-bit) is selected in alarm code selection C062, multi-function output terminals
P1 to P3, or P1 to P4, are forced to output an alarm code.
The following table shows the output alarm codes.
