Function Parameters 9-37
AC10 Inverter
9.7 Malfunction and Protection
F700 Selection of terminal free stop mode
Setting range:
0: free stop immediately;
1: delayed free stop
Mfr’s value: 0
F701 Delay time for free stop and programmable
terminal 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 the
terminal. 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 free
stop immediately.
“Delayed free stop” means that upon receiving “free stop” signal, the inverter will execute “free
stop” command after waiting some time instead of stopping immediately. Delay time is set by
F701. During the process of flycatching, the function of delayed free stop is invalid.
F702 Fan control mode
0: controlled by temperature
1: Running when inverter is powered on.
2: controlled by running status
Mfr’s value: 2
When 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 stop
until the heat sink temperature is lower than setting temperature.
F704 Inverter Overloading pre-alarm
Coefficient (%)
Setting range: 50～100
Mfr’s value: 80
F705 Motor Overloading pre-alarm
Coefficient (%)
Setting range: 50～100
Mfr’s value: 80
F706 Inverter Overloading Coefficient (%) Setting range: 120～190 Mfr’s value: 150
F707 Motor Overloading Coefficient (%)
Setting range: 20～100
Mfr’s value: 100
Inverter overloading coefficient: the ratio of overload-protection current and rated current,
whose value shall be subject to actual load.
Motor overloading coefficient (F707): when inverter drives lower power motor, set the value of
F707 by 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 the
overload protection speed. Please refer to Figure 9-20.
For example: 7.5kW inverter drives 5.5kW motor, F707=5.5/7.5 ×100％≈70％. When the
actual current of motor reaches 140% of inverter rated current, inverter overload protection will
display after 1 minute.
