H06
Fan stop operation
•
With this function, the temperature of the heat
sink is detected while the inverter is turned
on, to turn on or off the cooling fan
automatically. If this function is not selected,
the cooling fan rotates at all times.
Setting 0: No on/off control
1: On/off control (thermostat)
H07
ACC/DEC pattern (Mode select)
•
Select the acceleration/deceleration mode.
Setting 0: Inactive
(linear acceleration/deceleration)
1: S-curve acceleration/deceleration
(Weak)
2: S-curve acceleration/deceleration
(Strong)
3: Non-linear (for variable torque)
When the function is set at "1", "2" or "3", a
change in the acceleration or deceleration time
during acceleration or deceleration is not
reflected immediately. The setting becomes
effective after a constant speed is reached or
the inverter is stopped.
Selecting Functions
[S-curve acceleration/deceleration]
To reduce the shock of the mechanical system,
the change in the output frequency is made
smooth when the frequency is set.
