Functional Details 41
the motor load is too high, or the inverter is failed due to above reasons, it is
suggested to appropriately decrease the carrier frequency to improve thermal
characteristics of the inverter.

Parameter write protection
Setting range: 0 ~ 9999
This function is used to prevent improper modification of data.
1: Only allowing for modifying function parameter [F0.01] and this parameter.
2: Only allowing for modifying this parameter.
Other values: all parameters can be modified.
When it is forbidden to modify parameters, if it is intended to modify data,
“- -” will be displayed.
Some parameters cannot be modified during running. If it is
attempted to modify these parameters, “－－” will be displayed.
To modify parameters, stop the inverter at first.
F0.11
Torque boost
Setting range: 0.0 ~ 20.0（%）
It is used to improve inverter’s low-frequency torque characteristics. During
running at low frequency, it will make compensation for boosting inverter’s
output voltage, as shown in Figure 6-4.
