Note 1. In this manual, the parameter location for the 3G3MV is written ahead of the parameter lo-
cation for the 3G3RV/3G3PV/3G3FV, so "n035/o1-03" indicates a parameter location of
n035 for the 3G3MV and parameter location of o1-03 for the 3G3RV/3G3PV/3G3FV.
Note 2. The data setting unit can be changed with n35/o1-03 (frequency reference setting/display
unit).
Note 3. Data that exceeds the upper or lower setting range limits will be considered faulty and ig-
nored by the Inverter, and the previous data will be maintained.
Note 4. This function is only available with 3G3FV Inverters, which are equipped with flux vector con-
trol mode. It cannot be used with the 3G3MV/3G3RV/3G3PV Inverters.
Note 5. When not using either the torque limit of the torque reference, set F9-05 (torque refer-
ence/torque limit selection from communications) to 0 (disabled). If this setting is not dis-
abled and "0" is sent as data, the torque limit/torque reference will be set to 0, and there will
be no torque output (i.e., the motor will not operate).
Note 6. Although the setting range for torque reference/torque limit is − 300.0% to 300.0%, the
torque actually output depends on the motor characteristics. For a general-purpose motor,
take the range to be − 200.0% to 200.0%.
Specifies the Inverter output frequency from communications.
• Setting unit: 0.01 Hz (See note 2.)
• Setting range: 0 to maximum frequency in Hz (See note 3.)
Example: To set the frequency reference to 60.00 Hz:
60.00 Hz/(0.01 Hz) = 6000 decimal = 1770 hex → Set
as 1770 hex.
Specifies the torque reference or torque limit for the Inverter output.
(See notes 4 and 5.)
The torque limit/torque reference is only enabled when flux vector
control is set.
• Whether torque reference or torque limit is specified depends on
the Inverter's control mode.
Speed control: torque limit
• Setting unit: 0.1% (100% = motor rated torque)
• Setting range: − 300.0% to 300.0% (See note 6.)
Example: To set the torque reference to 10%:
10%/(0.1%) = 100 decimal = 64 hex → Set as 64 hex.
Specifies the torque compensation bias when using torque control.
(See note 4.)
Torque compensation bias is only available when performing torque
control in flux vector control mode. It is used separately from torque
control to compensate for mechanical torque loss.
• Setting unit: 0.1% (100% = motor rated torque)
• Setting range: − 300.0% to 300.0% (See note 6.)
Example: To set the torque compensation bias to 100%:
100.0%/(0.1%) = 1000 decimal = 3E8 hex → Set as
3E8 hex.)
