The count value is reset to 0 when the reset input comes ON. This counter operation is enabled while the soft-gate is ON.
8. Special I/O Functions Operation Count input Reset input Soft-gate Set value Count value Interrupt Sample program (H1003) In this example, 4099 (H1003) is set in SW16. As a result, the single phase up-counter (channel 1 only) is selected. When R010 comes ON, the data 2000 is written into the set value register (SW18). While R010 is ON, the soft-gate (S240) and the interrupt enable flag (S241) are set to ON to enable the counter operation. The counter works as a ring counter with the set value 2000.
8. Special I/O Functions 8.3.2 Single phase speed-counter Function This function counts the number of changes of the count input from OFF to ON during the every specified sampling time. The count value in a sampling time is stored in the hold value register. This counter operation is enabled while the soft-gate is ON. When the soft-gate is OFF, the hold value is cleared to 0. The setting range of the sampling time is 10 to 1000 ms (10 ms units). The count value range is H0000 to HFFFF (16-bit).

Special I/O Functions Operation Count input Sampling time DT DT DT DT DT DT Soft-gate Internal count value a b a e c d b e c d Hold value Sample program (H1403) In this example, 5123 (H1403) is set in SW16. As a result, the single phase speedcounter (channel 1 only) is selected. The sampling time is set as 100 ms, because 10 is written in SW18. While R010 is ON, the soft-gate (S240) is set to ON, and the speed-counter works. The hold value is stored in SW22.
8. Special I/O Functions 8.3.3 Quadrature bi-pulse counter Function This function counts up or down the quadrature bi-pulse (2-phase pulses whose phases are shifted 90° each other). Counts up when phase A precedes, and counts down when phase B precedes. Both rising and falling edges of each phase are counted. Consequently, 4 times count value against the pulse frequency is obtained.

8. Special I/O Functions Sample program (H0803) In this example, 2051 (H0803) is set in SW16. As a result, the quadrature bi-pulse counter is selected. When R010 comes ON, the data 150000 is set into the comparison value 1 register (SW19×SW18), and 200000 is set into the comparison value 2 register (SW21×SW20). While R010 is ON, the soft-gate (S240), the interrupt enable flag 1 (S241) and the interrupt enable flag 2 (S249) are set to ON to enable the counter operation.
8. Special I/O Functions 8.4 Interrupt input function Function When the signal state of the interrupt input is changed from OFF to ON (or ON to OFF), the corresponding I/O interrupt program is activated immediately. Up to 2 interrupt inputs can be used. The interrupt generation condition can be selected either rising edge (OFF to ON) or falling edge (ON to OFF) for each input.
8. Special I/O Functions Sample program Main program (H3045) I/O interrupt program #3 Interrupt program A I/O interrupt program #4 Interrupt program B In this example, 12357 (H3045) is set in SW16. As a result, the interrupt input function (2 points, rising for both) is selected. When X002 is changed from OFF to ON, the interrupt program A is executed. When X003 is changed from OFF to ON, the interrupt program B is executed.
8. Special I/O Functions 8.5 Analog setting function Function The value of the analog setting adjuster is converted into a digital value (0 to 1000) and stored in the SW register. 2 adjusters are provided. (V0 and V1) The SW register data can be used as timer presets or any parameters for function instructions.
8. Special I/O Functions 8.6 Pulse output function Function This function is used to output a variable frequency pulse train. The controllable pulse frequency is 50 to 5000 Hz (1 Hz units). The output mode can be selected either CW/CCW or Pulse/Direction (PLS/DIR). In the CW/CCW mode, CW pulse is output when the frequency setting is positive (50 to 5000), and CCW pulse is output when it is negative (-50 to -5000).
8. Special I/O Functions Operation Pulse enable Frequency setting 100 + 1000 300 -100 -1000 -300 1kHz Frequency 100Hz 300Hz Pulse output 100Hz - 300Hz 1kHz Sample program In this example, 3 (H0003) is set in SW26. As a result, the CW/CCW mode pulse output function is selected. When R000 is ON, the pulse output is started with the frequency designated by D0100.
8. Special I/O Functions 8.7 PWM output function Function This function is used to output a variable duty cycle pulse train. The controllable duty cycle is 0 to 100 % (1 % units). ON duty 50% 70% 60% T T T PWM T = Pulse cycle The PWM output is enabled when the pulse enable flag is ON. While the pulse enable flag is ON, the duty cycle (ON duty) can be changed by changing the duty setting value (0 to 100).
8. Special I/O Functions Operation Pulse enable ON duty setting 10 20 30 70% ON duty PWM output 70 10% 20% 60 60% 70 70% 30% Sample program In this example, 1 (H0001) is set in SW26 and 100 is set in SW28. As a result, 100 Hz PWM output function is selected. When R005 is ON, the PWM output is started with the duty cycle designated by D0200. If an invalid ON duty is designated, the ON duty setting error flag (S26E) comes ON and the pulse enable flag (S270) is turned OFF.
