This function allows the prohibit or “jumping” of critical frequencies so that the motor
can operate without resonance caused by machine characteristics. This function is also
used for dead band control. Setting the value to 0.00Hz disables this function.
Set prohibited frequency 1, 2 or as follows:
Continuous operation is prohibited within the jump frequency range.
However, during accel/decel the output frequency ramps through the jump frequency
range (without jumping).
Sets the inverter to restart and reset fault detection after a fault occurs.
The number of self-diagnosis and retry attempts can be set with n48 (0 thru 10 restarts).
The inverter will automatically restart after the following faults occur:
• OC (overcurrent)
• GF (ground fault)
• OV (over voltage)
The number of retry attempts are cleared to 0 during 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) Input power is turned OFF
Jump frequencies (n49 to n51)
n49 > n50
If this condition is not satisfied the
inverter displays
for one second
and restores the data to original
settings.
