F19: Function-boost Parameters
Cooling fan (F19.07 - F19.08)
Ref. code
Name Description
Setting Range [Default]
F19.07 Fan
control
0 - 2 [0]
F19.08
Fan control delay time
0.0 - 600.0 [60.0s]
Defines the control mode of cooling fan. With overheat protection, the fan runs all the time.
0: Auto stop.
•
The fan runs all the time when inverter is running. After inverter stops for the time set by F19.08, the
fan continues running if overheat protection is activated.
1: Immediate stop.
•
The fan runs all the time when inverter is running and stops when inverter stops.
2: Runs all the time when power on.
•
The fan runs all the time when inverter is powered on.
Stall overvoltage function (F19.18 - F19.19)
During running process of inverter, it will encounter DC busbar voltage increase and overvoltage
protection due to load inertia. DC busbar voltage may increase because of sudden increase /
decrease of load during dec process.
Ref. code
Name Description
Setting Range [Default]
F19.18
Overvoltage suppression gain
0.000 - 1.000 [0.000]
0: Forbid stall overvoltage.
0.001 - 1.000: Enable stall overvoltage.
•
When inverter is running, it detects busbar voltage and compares it with F19.19, if busbar voltage >
F19.19, inverter will increase output frequency to avoid large load feedback.
•
If F19.18 is too small, it can not effectively supress increase of busbar voltage.
•
If F19.18 is too large, output frequency will fluctuate even system oscillates; to avoide this problem,
increase duration of dec process.
Note: If stall overvoltage; asts for more than 1 minute, inverter reports stall overvoltage (E0007), and stops
output.
