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.
FU1-01: 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 Description
None
Forward &Reverse run available.
(Factory default)
Forward Prev Forward run prohibited.
Reverse Prev Reverse run prohibited.
FU1-02: Acceleration Pattern
FU1-03: Deceleration Pattern
Different combinations of acceleration and
deceleration patterns can be selected according to the
application.
Setting Range Description
Linear
A general pattern for constant torque
applications. (Factory default)
S-curve
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
This pattern provides more efficient
control of acceleration and deceleration
in typical winding machine applications.
Note: Setting value in DRV-01 and DRV-02 is ignored.
[Accel/Decel Pattern: ‘Linear’]
[Accel/Decel Pattern: ‘S-curve’]
Actual accel time = Preset accel time+ Preset accel
time *Starting curve ratio/2 + Preset accel time *
Ending curve ratio /2
Actual decel time = Preset decel time + Preset decel
