Cooling Fan ON/OFF Control
To prolong the life of the cooling fan and to reduce fan noise during running, the cooling fan is
stopped when the temperature inside the inverter drops below a certain level while the inverter is
stopped. However, since frequent switching of the cooling fan shortens its life, it is kept running
for 10 minutes once it is started.
This function code (H06: Cooling fan ON/OFF control) allows you to specify whether the cooling
fan is to be kept running all the time or to be controlled 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 the impact on the inverter-driven motor and/or its mechanical load during
acceleration/deceleration, the inverter gradually accelerates/decelerates the motor in both the
acceleration/deceleration starting and ending zones. Two types of S-curve
acceleration/deceleration 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.
