9-36 Function ParametersAC10 Inverter9.7 Malfunction and ProtectionF700 Selection of terminal free stop modeSetting range:0: free stop immediately;1: delayed free stopMfr’s value: 0F701 Delay time for free stop and programmableterminal action Setting range: 0.0~60.0 Mfr’s value: 0.0“Selection of free stop mode” can be used only for the mode of “free stop” controlled by theterminal. The related parameters setting is F201=1, 2, 4 and F209=1.When “free stop immediately” is selected, delay time (F701) will be invalid and inverter will freestop immediately.“Delayed free stop” means that upon receiving “free stop” signal, the inverter will execute “freestop” command after waiting some time instead of stopping immediately. Delay time is set byF701.F702 Fan control mode0: controlled by temperature1: Running when inverter is powered on.2: controlled by running statusMfr’s value: 2When F702=0, fan will run if the heat sink temperature is up to setting temperature.When F702=2, fan will run when inverter begins running. When inverter stops, fan won’t stopuntil the heat sink temperature is lower than setting temperature.F704 Inverter Overloading pre-alarm setpoint (%) Setting range: 50~100 Mfr’s value: 80F705 Motor Overloading pre-alarm setpoint (%) Setting range: 50~100 Mfr’s value: 80F706 Inverter Overloading Coefficient (%) Setting range: 120~190 Mfr’s value: 150F707 Motor Overloading Coefficient (%) Setting range: 20~100 Mfr’s value: 100Inverter overload pre-alarm (warning) setpoint (F704): the ratio of overload-protection currentand rated current, whose value shall be subject to actual load.Inverter overload setpoint (F706): the ratio of overload-protection current and rated current,whose value shall be subject to actual load. An inverter overload fault (OL1) will occur whenactual load exceeds this value for the specified time.Motor overload pre-alarm (warning) setpoint (F705): when inverter drives lower power motor,set the value of F707 by below formula in order to protect motor. A motor overload fault (OL2)will occur when actual load exceeds this value for the specified timeMotor overload setpoint (F707): when inverter drives lower power motor, set the value of F707by below formula in order to protect motor:Motor Overloading Coefficient = ×100%。Set F707 according to actual situation. The lower the setting value of F707 is, the faster theoverload protection speed, refer to Figure 9-12.For example: 7.5kW inverter drives 5.5kW motor, F707=5.5/7.5 ×100%≈70%. When theactual current of motor reaches 140% of inverter rated current, motor overload protection willdisplay after 1 minute.Rated motor powerRated inverter power
