9 Application Instructions API 150-199 3. Assume the first execution result as: Frequency 100KHz C251 =K50000 Y0 stops output D1340 Time Number D1348 D1343 3s 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 (D1131) to K101. 5. Obatin the result of the second execution:
Frequency 100KHz C251 =K50000 Y0 stops output D1340 Time Number D1348 D1343 300ms Actual number of output pulses (D1336, D1337) = K50,560 Estimated number of output pulses: 50,500 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 (D1131) 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. M1257: The acceleration/deceleration slope of the high-speed pulse output is an S curve. DVP-PLC Application Manual 9-137
