Jump Frequencies (n083 to n086)
This function allows the prohibition or "jumping" of critical frequencies
so that the motor can operate without resonance caused by the machine
system. This function is also used for dead band control. Setting the val-
ues to 0.00 Hz disables this function.
Set prohibited frequencies 1, 2, and 3 as follows:
Output Frequency
Operation is prohibited within the jump frequency ranges.
However, the motor will operate without jumping during acceleration/
deceleration.
Automatic Restart Operation (n082)
WARNING
The Inverter can be set to restart and reset fault detection after a fault
occurs. The number of self-diagnosis and retry attempts can be set to up
to 10 in n082. The Inverter will automatically restart after the following
faults occur:
OC (overcurrent)
OV (overvoltage)
The number of retry attempts is cleared to 0 in the following cases:
1. If no other fault occurs within 10 minutes after retry
2. When the Fault Reset signal is ON after the fault is detected
3. When the power supply is turned OFF
Frequency Reference
When the fault retry function is selected, stand clear of
the Inverter or the load. The Inverter may restart sud-
denly after stopping.
(Construct the system to ensure safety, even if the
Inverter should restart.) Failure to observe this warn-
ing may result in injury.
6 Programming Features
n083 ≥ n084 ≥ n085
If this condition is not satisfied,
the Inverter will display
one second and restore the
data to initial settings.
