H06
Cooling Fan ON/OFF Control
To prolong the 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. However,
since frequent switching of the cooling fan shortens its life, the cooling fan is kept running for 10
minutes once it is started.
H06 specifies whether to keep running the cooling fan all the time or to control its ON/OFF.

Acceleration/Deceleration Pattern
H07 specifies the acceleration and deceleration patterns (patterns to control output frequency).
Linear acceleration/deceleration
The inverter runs the motor with the constant acceleration and deceleration.
S-curve acceleration/deceleration
To reduce an impact that acceleration/deceleration would make on the machine (load), the
inverter gradually accelerates or decelerates the motor in both starting and ending zones of
acceleration/deceleration. Two types of S-curve acceleration/deceleration rates are available;
5% (weak) and 10% (strong) of the maximum frequency, which are shared by the four
inflection points.
The acceleration/deceleration time command determines the duration of acceleration/
deceleration in the linear period; hence, the actual acceleration/deceleration time is longer
than the reference acceleration/deceleration time.
