9 Application Instructions API 150-199
DVP-PLC Application Manual
9-99
3. Assume the first execution result as:
100KHz
D1340
D1348D1343
C251 =K50000
3s
Frequency
Y0 stops output
Time
Number
Estimated number of output pulses: 50,000
Actual number of output pulses (D1336, D1337) = K50,600
4. Observe the result of the first execution:
a) The actual output number 50,600 – estimated output number 50,000 = 600
b) 600 x (1/200Hz) = 3s (idling time)
c) 3 seconds are too long. Therefore, increase the percentage value (D1198) to K101.
5. Obatin the result of the second execution:
100KHz
D1340
D1348D1343
C251 =K50000
300ms
Frequency
Y0 stops output
Time
Number
Estimated number of output pulses: 50,500
Actual number of output pulses (D1336, D1337) = K50,560
6. Observe the result of the second execution:
a) The actual output number 50,560 – estimated output number 50,500 = 60
b) 60 x (1/200Hz) = 300ms (idling time)
c) 300ms is an appropriate value. Therefore, set the percentage value (D1198) as K101 to complete the
design.
Remarks:
1. Flag explanations:
M1010
When On, CH0, CH1, CH2 and CH3 will output pulses when encountering END instruction. Off
when the output starts.
M1029
On when CH0 pulse output is completed.
M1030
On when CH1 pulse output is completed.
M1036
On when CH2 pulse output is completed.
M1037
On when CH3 pulse output is completed.
M1334
When On, CH0 pulse output will be forbidden.
M1335
When On, CH1 pulse output will be forbidden.
