VB5N series inverter

Swing frequency running mode
Lowest bit of LED:input mode
0: Auto input mode. The inverter will run at preset frequency (P9.02) for a while (P9.03), and then enter the swing fre-
quency status.
1: Terminal manual input mode. If the multi-function terminal (Xi is set to No.25 function) is enabled, the inverter will
enter swing frequency status. If the terminal is disabled, the inverter will quit swing frequency and run at preset swing fre-
quency (P9.02).
Ten bit of LED: swing frequency width
0: Variable width. Width AW changes with the center frequency and the changing rate is defined by P9.04.
1: Fixed width. Width AW is decided by max frequency and P9.04.
Waiting time of preset swing frequency
P9.02 is used to set running frequency before entering swing frequency.
If you select auto start mode, P9.03 is used to set the running lasting time at preset swing frequency before the inverter
enter swing frequency; if you select manual start mode, P9.03 is disabled. Refer to Fig. 4-45.
The width of swing frequency
Variable width: Aw=Center frequency×P9.04
Fixed width: Aw=Max running frequency P0.06×P9.04
Prompt: The swing frequency is limited by upper/lower frequency, it will work abnormal if set uncorrect.
As shown in Fig4-45, there is no jump frequency if P9.05 = 0.
It defines the complete period of swing frequency up/down process.
Running time of swing frequency up stage =P9.06×P9.07(s), Time of down stage=P9.06×(1-P9.07)(s). Refer to
Fig.4-45.
Note: You can select S-curve Acc/Dec mode along with swing frequency, the swing frequency will run more smoothly.
Calibration coefficient of length
These parameters are used to realize fixed length control.
The counting pulses is input via terminal (X6, defined as function 35), and calculate the length according to the pulses per
revolution (P9.13) and perimeter of shaft (P9.12).
Calculated length=counting pulses÷ pulses per revolution×perimeter of shaft
The length can be corrected through times of length (P9.10) and calibration coefficient of length (P9.11), and the length is
the actual length.
Actual length =calculated length×calibration coefficient of length÷calibration coefficient of length
When actual length (P9.09) ≥ preset length (P9.08), the inverter will send out STOP command.When the inverter restarts,
it needs to clear the actual length (P9.09) or make the actual length (P9.09) less than preset length (P9.08), otherwise the
inverter will not start.
