H06 Cooling Fan ON/OFF Control
To prolong the service life of the cooling fan and reduce fan noise during running, the cooling
fan stops when the temperature inside the inverter drops below a certain level while the
inverter stops.
H06 specifies whether to keep running the cooling fan all the time or to control its ON/OFF.
Data for H06

1
Cooling fan in operation -- FAN (E20 to E24 and E27, data = 25)

With the cooling fan ON/OFF control enabled (H06 = 1), this output signal is ON when the
cooling fan is in operation, and OFF when it is stopped. This signal can be used to make the
cooling system of peripheral equipment interlocked for an ON/OFF control
H07 Acceleration/Deceleration Pattern
For details, refer to the description of F07.
H08 Rotational Direction Limitation
H08 inhibits the motor from running in an unexpected rotational direction due to
miss-operation of run commands, miss-polarization of frequency commands, or other
mistakes.

H09 Starting Mode (Auto search)
H09 specifies the starting mode--whether to enable the auto search for idling motor speed to
run the idling motor without stopping it.
The auto search can apply to the restart of the inverter after a momentary power failure and
the normal startup of the inverter individually.
If the terminal command STM ("Enable auto search for idling motor speed at starting") is
assigned to a digital input terminal with any of E01 to E07 (data = 26), then the combination
of the H09 data and the STM status switches the starting modes (whether auto search is
enabled or disabled). If no STM is assigned, the inverter interprets STM as being OFF by
default.
