Jumping frequency and jumping range relationship
Note: 1. The output frequency still will pass the jumping range during acceleration or deceleration. Make
sure the parameters don't overlap or inset setting.
2. Jumping frequency is disabled for jog, multi-step speed and swing frequency.
E-43
Number of auto restart
attempts
Range:0-3 Default:0
E-44
Fault auto reset waiting time Range:0.1-20.0s
Default:1.0s
Number of automatic fault reset:
0
:
Disable, The auto reset function is disabled, reset only by manual.
1—3: Enable, 1-3 parameters used for defining the numbers of auto reset. (The maximum time of auto reset is
enabled)
The inverter may be trip to stop cause by fluctuation of grid and other accidents reason during operation. Auto reset
for overload, over current, system abnormal, overvoltage, under voltage. etc fault occurs is allowable to restart
inverter operation ensure system working continuously. Inverter will restart with speed search restart mode during
auto reset.
If the auto reset fails to restart during the setting give numbers, the fault protection will be activate, inverter stop
output. The maximum of auto reset number setting is 3, the reset numbers will be recount after inverter running
normally for 10 minutes, the record times clears automatically. Suggest configure number of auto reset to 1 times
will be better.
The fault output terminal can be set disable or enable during fault auto reset process. Refer to
[F-30,F-31,F-32]
Fault auto reset waiting time: Uses for defining the waiting time from fault occurs to reset attempts.
Note: 1. This function only enable for overload, over current, system abnormal, over voltage, under voltage
during running, disable for other fault happen.
2. Reset can’t make if fault fail to solve, no reset for the temperature of inverter over 70
℃
Tips: Users must be cautious to consider the start characteristic of the mechanical devices in crane, lifting
application. It should be cautious in using this function for application which can’t start with load or the
alarm will come out immediately when inverter stop output.
E-45
Machine warm up time
Range:0.0-6500s Default:0.0s
Inverter enables command operation after machine warm up time, once power supply switch to inverter. It displays
count down in seconds after switch on.
E-46
Running direction selection Range:0-2
Default:0
0: Consistent with the default direction
Actual rotation direction is the same with the requirement. The
actual direction don’t change.
