Operation in V/f Control
This mode, which is used by conventional general-purpose inverters, is convenient
when replacing a conventional model with the 3G3MV Inverter because the Inverter in
this mode can be operated without considering the constants of the motor. Furthermore,
set the Inverter to this mode if the Inverter is connected to two or more motors or special
motors, such as high-speed motors.
To operate the Inverter in V/f control mode, be sure to set n036 for the rated motor cur-
rent and n011 through n017 for the V/f pattern.
5-3-1 Setting the Rated Motor Current (n036)
•
Check the motor nameplate and set this parameter to the rated current.
•
This set value is used for determining the electronic thermal characteristics to protect the motor from
overheating. The correct set value protects the motor from burning that may result from overloading.

1.
Note 1.
The default setting for this parameter is the standard rated current of the maximum applicable
motor.
Note 2.
Motor overload detection (OL1) is disabled by setting the parameter to 0.0.
5-3-2 Setting the V/f Patterns (n011 to n017)
•
Set the V/f pattern so that the motor output torque is adjusted to the required load torque.
•
The 3G3MV incorporates an automatic torque boost function. Therefore, a maximum of 150% torque
can be output at 3 Hz without changing the default settings. Check the system in trial operation and
leave the default settings as they are if no torque characteristic changes are required.
