on the fan control function code (F15.34). The specific running mode of the fan is shown in
Table 7-21 Details of Fan Operation
Fan control
Fan operation
0: running after
power-on
When the inverter is powered on, the fan will start running.
1: running at startup
When the inverter starts running, the fan will start running. When
this parameter is set to 1 min, the fan will stop running.
2: intelligent operation,
subject to temperature
control
When the temperature of the inverter is greater than 45°C, the fan
will start running; when the temperature of the inverter is less
than 40°C, the fan will stop running; and when the temperature of
the inverter is in between the two values, the fan will remain
unchanged.
★
When “2: intelligent operation, subject to temperature control” is selected, make
sure that the temperature detection module of the inverter works properly.

Overmodulation intensity 1.00 - 1.10
1.05
●
When the input voltage of the inverter is lower than the output voltage, you can
increase the overmodulation intensity to improve the bus voltage utilization and thus
increase the upper limit of output voltage. When F15.35=1.10, the upper limit of output
voltage can be increased by 10%, thus reducing the output current under heavy loads, but
the current harmonics will increase.

Terminal jog priority

0
○
In the terminal control mode (F00.02=1), this function code is used to set the highest
priority of the jog command. If the terminal jog priority is valid (F15.39=1), the running
status can be switched to jog running in the presence of a valid jog terminal; and if the
terminal jog priority is invalid (F15.39=0), the running status cannot be directly switched to
jog running.
