FU1-00: Jump to Desired Code #

FU1? Jump code
00 1
Factory Default:
1
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

FU1? Run prev.
03 None
Factory Default:
None
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.

Chapter 6 - Parameter Description [FU1]
Different combinations of acceleration and deceleration
patterns can be selected according to the application.
Setting Range
LCD 7-Seg
This is a general pattern for constant
Linear 0
torque applications.
This pattern allows the motor to
accelerate and decelerate smoothly. The
actual acceleration and deceleration time
takes longer- about 40% than the time set
1
S-curve 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.
This pattern provides more efficient
2
U-curve control of acceleration and deceleration in
typical winding machine applications.
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.
Minimum 3
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.
The inverter accelerates with a current
rate of about 120% of its rated current
4
Optimum
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.
