modifying, please save valid password properly.
0-01 Acceleration Time
Factory Value: 3.0
Setting Range: 0.1
～
300.0S
Acceleration time is the time of the period from 0Hz to 50 Hz in beginning operation of the converter. This
parameter is inappropriate to set too short, if that it is easy to jump to “OC” protection.
0-02 Deceleration Time
Factory Value: 3.0
Setting Range: 0.1
～
300.0S
Deceleration Time is the period from 50Hz to 0Hz of the converter operating frequency in deceleration
process. This parameter is inappropriate to set too short, if that it is easy to jump to “OE” protection.
0-03 Carrier Frequency
Factory Value: 3
Setting Range: 2
～
10 KHz
Carrier Frequency is namely the
chopper frequency, which means the pulse frequency of PWM waves of the
converter output. The higher the
Carrier Frequency, the lower the
electromagnetic noise of the motor; but the
wear and tear
of the switch would increase and the temperature rise also will be raised. So with the power of the
converter increasing, ought to decrease the
Carrier Frequency.
0-04 Selection of the
Torque
Factory Value: 4
Setting Range: 1
～
18
Compensation
Curve
In order to compensate the torque characteristics of the motor at lower frequency, the converter set up the following
torque compensation curve (V / F curve), which should be used in accordance with the specific circumstance, in
general circumstance do not have to be adjusted again.
