YASKAWA Varispeed V7 - Jump Frequencies (n083 to n086); Continuing Operation Using Automatic Retry Attempts (n082)

148
Frequency Detection 2
Output frequency ≤ Frequency Detection Level n095
(Set n057, n058 or n059 to 5.)
 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:
Operation is prohibited within the jump frequency ranges.
However, the motor will operate without jumping during acceleration/
deceleration.
 Continuing Operation Using Automatic Retry Attempts (n082)
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.
