6.2 Function 1 Group [FU1]
FU1-00: Jump to Desired Code #
Jumping directly to any parameter code can be
accomplished by entering the desired code number. This
code is available only with LCD keypad.
FU1-03: Run Prevention
This function prevents reverse operation of the motor. This
function may be used for loads that rotate only in one
direction such as fans and pumps.
Setting Range
LCD 7-Seg
Description
None 0 Forward and Reverse run is available.
Forward Prev 1 Forward run is prevented.
Reverse Prev 2 Reverse run is prevented.
FU1-05: Acceleration Pattern
FU1-06: Deceleration Pattern
Different combinations of acceleration and deceleration
patterns can be selected according to the application.
Setting Range
LCD 7-Seg
Description
Linear 0
This is a general pattern for constant
torque applications.
S-curve 1
This pattern allows the motor to
accelerate and decelerate smoothly. The
actual acceleration and deceleration time
takes longer- about 40% than the time set
in DRV-01 and DRV-02.
This setting prevents shock during
acceleration and deceleration, and
prevents objects from swinging on
conveyors or other moving equipment.
U-curve 2
This pattern provides more efficient
control of acceleration and deceleration in
typical winding machine applications.
Minimum 3
The inverter makes shorten the
acceleration time by accelerating with a
current rate of about 150% of its rated
current and reduces the deceleration time
by decelerating with a DC voltage rate of
95% of its over-voltage trip level.
Appropriate application: When the
maximum capability of the inverter and
the motor are required.
Inappropriate application: The current
limit function may operate for a long
period of time for loads that have high
inertia such as fans.
Optimum 4
The inverter accelerates with a current
rate of about 120% of its rated current
and decelerates with a DC voltage rate of
93% of its over-voltage trip level.
☞
Note: In case of selecting the ‘Minimum’ or ‘Optimum’, the
DRV-01 and DRV-02 is ignored.
☞ Note: ‘Minimum’ and ‘Optimum’ functions operate normally
when the load inertia is less than 10 times compared to the
motor inertia. (FU2-37)
☞ Note: ‘Optimum’ is useful when the motor capacity is
smaller than the inverter capacity.
☞ Note: ‘Minimum’ and ‘Optimum’ functions are not
appropriate for down operation in an elevator application.
