6. 7. 2 Run/stop with a frequency command
<F241: Run frequency>
<F242: Run frequency hysteresis>
■ Function
You can run/stop the motor with only a frequency command when a run command remains ON.
When the frequency command reaches the set frequency value, the inverter will start to run. When it
becomes below the set value, the inverter will stop.
■ Parameter setting
■ Setting method
When the frequency command reaches the setting value of <F241: Run frequency>, the inverter will
start to run. When the command becomes below the setting value, the inverter will stop.
To prevent the inverter from repeatedly running/stopping around the frequency set with <F241: Run
frequency>, use <F242: Run frequency hysteresis> to provide hysteresis.
Set the parameter, referring to the following figure.
