V/f control mode selection
1) Constant torque characteristics (Normal way of use)
Setting of V/f control mode selection
This is applied to loads with equipment like conveyors and cranes that require the same torque at low speeds as at
rated speeds.
Base frequency voltage 1
[V]/[%]
* To increase the torque further, increase the setting value of the manual torque boost parameter
