7.14 F19: Enhancement Parameters
(F19.07, F19.08)
Ref. Code Function Description Setting Range [Default]
F19.07 Cooling fan control options 0 - 2 [0]
Cooling fan control delay time
F19.07 defines the control mode of the cooling fan. If there is over-temperature protection, the fan keeps
running.
0: Auto stop mode.
• When the inverter is running and the fan shut downtime reaches the time set by F19.08, if no
overtemperature protection occurs, the fan will stop automatically.
1: Immediate stop mode.
• When the inverter is running, the fan is running and the fan stops immediately after shutdown.
2: The fan is runningwith power on.
• The fan keeps running when the inverter is powered .
Note: F19.07, F19.08 fan control function only for 380V models, other models fan keeps running with power.
-stop function in instantaneous electric (F19.12 - F19.15)
In the voltage drop or instantaneous undervoltage, the inverter automatically low voltage
compensation, appropriate to reduce the output frequency, through the load feedback energy,
to achieve the inverter does not trip.
Ref. Code Function Description Setting Range [Default]
The non-stop function selection in instantaneous electric
If the inverter is momentarily lost during
operation (main circuit DC bus voltage VDC <
F19.15), the inverter maintains the DC bus voltage
by reducing the output frequency to avoid
undervoltage shutdown.
0: No.
1: Enable.
F19.13 Deceleration time in non-stop function 0.01 - 600.00 [5.00s]
Set too large, the load feedback energy is small, can not be used for low voltage compensation.
Set too small, the load feedback energy is large, will cause overvoltage protection.
