63
Value Function Range (Corresponding to Pulse or Analog Output Range 0.0%~100.0%)
12 AI2 0V~10 V
13 AI3 0V~10 V
14 Length 0~ maximum set length
15 Count value 0 ~ maximum count value
16 Communication setting 0~32767
b6-03
Maximum FMP output frequency Default 50.00 kHz
Setting Range 0.01 kHz ~50.00 kHz
If the FM terminal is used for pulse output, this parameter is used to set the maximum frequency of pulse output.
b6-04
AO1 offset coefficient Default 0.0%
Setting Range
-100.0% ~100.0%
b6-05
AO1 gain
Default
1.00
Setting Range
-10.00~10.00
b6-06
AO2 offset coefficient Default 0.0%
Setting Range -100.0% ~100.0%
b6-07
AO2 gain
Default
1.00
Setting Range
-10.00~10.00
These parameters are used to correct the zero drift of analog output and the output amplitude deviation. They can also
be used to define 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%.

VDI1~ VDI5 have the same functions as DI terminals on the control board and can be used for digital input. For more
details, see description of b3-00 ~ b3-11.
