Warning:
When setting the V/F control mode selection 1 parameter (
to set at least the following parameters.
Set also other torque boost parameters (
1) Constant torque characteristics
This is applied to loads with equipment like conveyors and cranes that require the same torque at low
speeds as at rated speeds.
5
* To increase the torque further, increase the setting value of the manual torque boost
2) Setting for fans and pumps
This is appropriate for load characteristics of such things as fans, pumps and blowers in which the torque in
relation to load rotation speed is proportional to its square.
(Motor rated current): See the motor's nameplate.
(No-load current of motor): Refer to the motor test report.
(Rated rotational speed of motor): See the motor's nameplate.
