The above function codes generally used to bias the output amplitude of zero drift and
correcting the analog output. It can also be used to customize the desired analog output curve.
Calculation relationship with DA1 example:
y1 represents DA1 minimum output voltage or current value; y2 represents DA1 maximum
output voltage or current value
y1=10V or 20mA*F2.16*100%
；
y2=10V or 20mA*(F2.16+F2.17)
；
Factory Default F2.16 = 0.0%, F2.17 = 1, so the output 0 ~ 10V (or 0 ~ 20mA) corresponding
to characterize the physical minimum value to characterize the physical maximum.
Example 1:
0 ~ 20mA output will be changed to 4 ~ 20mA
The minimum input current value from the formula: y1 = 20mA * F2.16 * 100%,
4=20*F2.16, calculated according to the formula F2.16=20%
；
Maximum input current value by the formula:y2=20mA*(F2.16+F2.17)
；
20=20*(20%+F2.17),calculated according to the formula F2.17=0.8
Example 2:
0 ~ 10V output will be changed to 0 ~ 5V
The minimum input voltage value from the formula:y1=10*F2.16*100%
，
0=10*F2.16, calculated according to the formula F2.16=0.0%
；
The maximum input voltage value from the formula: y2=10*(F2.16+F2.17)
；
5=10*(0+F2.17),calculated according to the formula F2.17=0.5

0
☆
0: Directly start-up, inverter start running from starting frequency.

0.0s
★
When the inverter starts, firstly run at the start frequency, the running time is the hold time for
start frequency, afterwards run at the frequency reference.
The start frequency F3.03 is not limited by the lower limit frequency. But if the set target
frequency is less than the start frequency, the inverter does not start and keeps in the standby state.
The hold time for start frequency is inactive when switching between forward rotation and
reverse rotation The hold time for start frequency is not included in the acceleration time, but the
simple PLC run-time. Example 1:
F0.03
＝
0 the frequency source is set to digital reference
F0.01
＝
2.00Hz the digital set frequency is 2.00Hz
F3.03
＝
5.00Hz the start frequency is 5.00Hz
F3.04
＝
2.0s the hold time for start frequency is 2.0s, at this time, the inverter will be in
the standby state with the output frequency of 0.00Hz.
Example 2:
F0.03
＝
0 the frequency source is set to digital reference
F0.01
＝
10.00Hz the digital set frequency is 10.00Hz
