4. Program explanation
When PLC goes from STOP to RUN, because VFD-B model A offers analog voltage output 0 ~ 10VDC to
06XA, you have to set CH1 as voltage input mode (mode 2) and CH5 as voltage output mode (mode 0).
In addition, set the average times of the input signals at CH1 as 10.
Save the present digital value of the input signal measured into D50.
In the voltage input mode of 06XA, The value range for 0 ~ 10V DC is K0 ~ K32,000. Data in D50 is
3,200 times of the actual voltage value (i.e. 32,000/10 = 3,200). Divide the value in D50 by 3,200 and
store the value obtained into D0 which represents the actual voltage measured.
Frequency range 0 ~ 50.0Hz corresponds to 0 ~ 10V. Multiply the value in D0 with 5 and store the value
obtained into D4 which represents actual frequency value
In the voltage output mode of 06XA, the value range for -10V ~ 10V is K-32,000 ~ K32,000. D4 is the
frequency of VFD-B model A. FWD/REV frequency -50Hz ~ 50Hz corresponds to K-32,000~ K32,000
(32,000/50 = 640). Multiply the value in D4 with 640 and store the digital value obtained into D60 which
represents the corresponding digital value of Ch5 output voltage.
5. Program example
Ladder diagram: Explanation:
Set CH1 as mode 0
Set the average times of CH1 signals as 10
Store the average digital value of CH1 signals
into D40
Store the present digital value of input signals
into D50
D50/3200 = D0, the voltage measured
D0*5 = D4, the output frequency of VFD-B
model A
Multiply D4 with 640 to obtain the output value
of VFD-B Model B.
