Check the motor name plate and set the following parameters first.
- <vL: Base frequency 1> (Rated frequency)
- <vLv: Base frequency voltage 1> (Rated voltage)
- <F405: Motor rated capacity>
- <F415: Motor rated current>
- <F417: Motor rated speed>
Next, set <Pt: V/f Pattern>. For details of setting methods, refer to [5. 3. 4].
Then, select <F400> = "4: Motor parameters auto calculation (0 after execution)" and calculate
motor parameters automatically.
Motor parameters <F402: Automatic torque boost>, <F412: Leakage inductance>, and <F416:
Motor no load current> will be set automatically.
This setting can be made without connecting the motor since it only calculates.
After automatic setting of motor parameter with <F400> = "4", be sure to set <F400> to "2: Auto-
tuning at run command (0 after execution)" and perform an auto-tuning.
You can set <F400> to "4" and "2" collectively by setting <F400> to "5: 4+2 (0 after excecution)".
Since calculation is performed based on general trend, the calculation results may not be correct. In
this case, set the parameter manually. In case ETN3 trip occurs after set 4 to F400 , do not set 4 to
F400, and set the parameter manually.
■ Setting method 4: Manually setting motor parameter
Set <Pt: V/f Pattern> and set the motor parameter manually.
If tuning error "Etn1" is displayed during auto-tuning setting or when you want to improve vector
control characteristics, set motor parameters individually.
