Chapter 6 - Parameter Description [AFN]
6-29
Note: The drive decreases the retry number by one
as each fault occurs. If a trip does not occur after
the drive is running for 30 seconds, the drive
increases the retry number by one until it reaches
the amount in AFN-25.
AFN-27: Flying Percentage
This parameter limits the output current during Speed
Search/Flying Start. Percentage is based on DRV-05,
Motor Amps.
AFN-40: Motor Capacity Selection
AFN-41: Number of Motor Poles
AFN-42: Rated Motor Slip
AFN-44: No Load Motor Current
AFN-45: Motor Efficiency
AFN-46: Load Inertia
If the user does not set these values, the drive will use
factory default values.
This parameter sets the motor capacity. The following
parameters are automatically set according to motor
capacity.
AFN-42 Rated Motor Slip
DRV-05 Rated Motor Current (Recheck DRV-05 after
changing HP setting).
AFN-44 No Load Motor Current
AFN-62 Stator Resistance
AFN-63 Rotor Resistance
AFN-64 Leakage Inductance
If AFN-44 [Motor No-load Current] is not correct, run
the drive without the load in V/F mode and check the
current at the constant run state and enter this value to
AFN-44 [No load current].
This is used to display the motor speed. If you set this
value to 2, the drive will display 3600 rpm instead of
1800 rpm at 60Hz output frequency. (See motor
nameplate)
CAUTION
Careful attention must be directed to this function
as the motor restarts automatically after a fault is
reset.
