5-10-7 0-Hz Detection Signal (ZS)
• Use this function to output a detection signal when the output frequency of the inverter falls below the
0 Hz Detection Level (C063).
• Allocate one of the Multi-function Output P1 to P5 Selection (C021 to C025) or the Multi-function
Relay Output (MA, MB) Function Selection (C026) to 21 (ZS) to enable this function.
• This function works upon the inverter output frequency when the control method is set to Constant
torque characteristics, Reduced torque characteristics, Free V/f setting, Sensorless vector control, or
0-Hz sensorless vector control, or upon the motor rotation frequency when the control method is set
to Sensor vector control.
• This signal will be output when the inverter becomes ready to run (ready to accept the RUN
command).
• When this command is not output, the inverter does not recognize the RUN command even if it is
input.
• If this signal is not output, check if the input power supply voltage (R, S, T) is within the specified
range.
• Allocate one of the Multi-function Output P1 to P5 Selection (C021 to C025) or the Multi-function
Relay Output (MA, MB) Function Selection (C026) to 50 (IRDY) to enable this function.
