High starting torque pattern 7.5.3
Group Code Parameter Name Setting Range Default Unit
Function group 1 F30 [V/F pattern] 3, 4 0 - 4 0
Set F30 to {3 High starting torque 1} or {4 High starting torque 2}.

iG5H offers a Two types of high starting torque pattern suitable for special pump load

requiring high starting torque.
Otherwise Select high starting torque when: Wiring between the drive and motor

exceeds 150 m, An AC reactor is installed.
User V/F pattern operation 7.5.4
Group Code Parameter Name Setting Range Default Unit
Function
group 1
F30 [V/F pattern] 2 0 - 4 0
F31 [User V/F frequency 1] - 0 - 400 15.00 Hz
- -
F38 [User V/F voltage 4] - 0 - 100 100 %
Select F30 to 2 {User V/F}.

User can adjust the Volt/Frequency ratio according to V/F pattern of specialized motors

and load characteristics.
In case of using a standard induction motor, if this value is set much higher than linear V/F
pattern, it could result in torque shortage or motor overheating due to over-energizing.
When User V/F pattern is active, F28 - [Torque Boost in forward direction] and F29 - [Torque
Boost in reverse direction] are deactivated.
