Function Code Parameter Name Setting Range Default
F5-10 AO1 offset coefcient -100.0%–100.0% 0.0%
F5-11 AO1 gain -10.00–10.00 1.00
F5-12 AO2 offset coefcient -100.0%–100.0% 0.00%
F5-13 AO2 gain -10.00–10.00 1.00
These parameters are used to correct the zero drift of analog output and the output
amplitude deviation. They can also be used to dene the desired AO curve.
If "b" represents zero offset, "k" represents gain, "Y" represents actual output, and "X"
represents standard output, the actual output is: Y = kX + b.
The zero offset coefficient 100% of AO1 and AO2 corresponds to 10 V (or 20 mA). The
standard output refers to the value corresponding to the analog output of 0 to 10 V (or 0 to
20 mA) with no zero offset or gain adjustment.
For example, if the analog output is used as the running frequency, and it is expected that
the output is 8 V when the frequency is 0 and 3 V at the maximum frequency, the gain shall
be set to -0.50, and the zero offset shall be set to 80%.
Function Code Parameter Name Setting Range Default
F5-17 FMR output delay time
0.0–3600.0s 0.0s
F5-18 Relay 1 output delay time
0.0–3600.0s 0.0s
F5-19 Relay 2 output delay time

These parameters are used to set the delay time of output terminals FMR, relay 1, relay 2,
DO1 and DO2 from status change to actual output.
