FU2-26: Number of Auto Restart Attempt
FU2-27: Delay Time Before Auto Restart
This function is used to allow the inverter to reset
itself for a selected number of times after a fault
has occurred. The inverter can restart itself
automatically when a fault occurs. To use the
speed search function during auto restarting set
FU2-22 to ‘xx1x’. See FU2-22 ~ FU2-25.
When an under voltage (LV) fault, inverter disable
(BX) or Arm short occurs, the drive does not
restart automatically.
☞
Note: Inverter decreases the retry number by one as a fault
occurs. When restarted without a fault during 30 seconds, the
inverter increases the retry number by one.
FU2-30: Rated Motor Selection
FU2-31: Number of Motor Pole
FU2-32: Rated Motor Slip
FU2-33: Rated Motor Current
FU2-34: No Load Motor Current
FU2-36: Motor Efficiency
FU2-37: Load Inertia
If you do not set these values, inverter will use its
default values.
This parameter sets the motor capacity. Other
motor related parameters are changed
automatically according to motor capacity. The
motor related parameters are FU2-32 [Rated
Motor Slip], FU2-33 [Rated Motor Current], FU2-
34 [No Load Motor Current].
