F02.02
Starting
frequency
Setting range: 0.00 ～
20.00Hz
Default value:
1.50Hz
F02.03
Hold time of
starting frequency
Setting range: 0.0～60.0s
Default value:
0.0s
To ensure the torque at start-up, set the appropriate starting frequency. In
addition, set up magnetic flux to wait for the start of the motor, so that the starting
frequency maintains a certain time before acceleration. The starting frequency
F02.02 is not limited by the lower limit frequency. When the frequency reference
is less than the starting frequency, the inverter cannot start and keep in standby
state. When switching forward running and reverse running, the hold time of
starting frequency does not work.
F02.04
DC braking
current before
start
Setting range: 0.0～160.0%
Default value:
0.0%
F02.05
DC braking time
before start
Setting range: 0.0～60.0s
Default value:
0.0s
DC braking current before start refers to motor rated current (F01.06).
DC braking time before start sets the operating time of the braking current.
The braking current before starting will affect the magnetic field strength of the
fixed motor shaft. Increase the braking current value and then the heat generated
by the motor in deceleration increases. Set the minimum DC braking current
required for the fixed motor shaft.
F02.06
ACC and DEC
mode
Setting range: 0～1
Default value: 0
0: linear type
The output frequency (speed) rises or falls evenly, that is constant ACC/DEC
mode. The ACC/DEC event varies according to the set ACC/DEC time.
The output frequency increases or decreases progressively at a constant slope
as shown in the following figure:
