1) Constant torque characteristics
Setting of V/F control mode selection to (V/F constant)
This is applied to loads with equipment like conveyors and cranes that require the same torque at low
speeds as at rated speeds.

* To increase the torque further, increase the setting value of the manual torque boost value 1 ().
Refer to section 6.4 for details.
2) Setting for fans and pumps
Setting of V/F control mode selection to (variable torque)
This is appropriate for load characteristics of such things as fans, pumps and blowers in which the torque is
proportional to the square of load rotation speed.
