Xinje VH6 Series - Vfd Operation Frequency; Swing Frequency Function

42
Under the VF control mode, if the actual acceleration time of the motor is much longer than the set acceleration
time, the following measures can be taken:
Frequency setting
Measures
Target frequency is less than 2 times rated
frequency
Increase P5-19 (VF over current stall action current) and adjust it by
10% each time. If P5-19 setting value exceeds 170%, it is easy to
cause ERR10 (frequency converter overload fault)
The target frequency is 3 times or more
than 4 times the rated frequency
In the process of rapid acceleration, motor stall is likely to occur.
Therefore, P5-22 (VF over current stall action current compensation
coefficient)can be adjusted, and the set value is 100%.
Under the VF control mode, if it is found that the actual deceleration time of the motor is much longer than the
set deceleration time, the following measures can be taken:
Braking resistor / Energy feedback unit
Measures
None
The set value of P5-16 (VF over excitation gain) can be increased by ±
20 each time. After increasing the over excitation gain, if the motor
oscillation overvoltage fault is caused, please reduce the set value of
P5-26(Over voltage stall suppression voltage gain).
Yes (input voltage of frequency
converter is 323~437V)
Adjust P7-52 to 690V and P5-16 (
Overexcitation gain
) to 0.
Using Shutdown DC braking, the recommended setting values: P4-23
=0.5Hz, P4-25=50%, P4-24= 1s
Note: when using braking resistor: P5-16 (Overexcitation gain) is set to 0, otherwise it is easy to cause
excessive current during operation. P5-24 (Overvoltage stall enable) is set to 0, otherwise the deceleration time
may be too long.
3-4. VFD operation frequency
The frequency converter is equipped with two frequency setting channels, named as main frequency source A
and auxiliary frequency source B, which can work in a single channel or switch at any time, or even set
calculation method for combination, so as to meet the different control requirements of the application site.

3-5. Swing frequency function
The swing frequency function refers to the frequency output of the frequency converter, which swings up and
down with the set frequency as the center. In the textile and chemical fiber processing equipment, the frequency
