4.16 PWM Output Function
(4) Operation example of the PWM output function
The following figure shows an operation example of the PWM output function when Coincidence output 3 is
assigned to the corresponding channel in the "Coincidence output 1 to 8 channel assignment setting" in the
switch setting.
● The waveform that is output from the coincidence output 1 to 8 terminal (EQU 1 to EQU8), the external output terminals,
can be affected by output circuits or connected devices and change its form.
So check the waveform by using, for example, a synchroscope, and then set the output waveform.
● The PWM waveform is output starting with OFF.
● When changing the output waveform, turn off CH1 Cam switch function/PWM output start command (Y08) to turn off CH1
Cam switch function execution/PWM output (X08).
After confirming that CH1 Cam switch function execution/PWM output (X08) is OFF, change the setting of CH1 On width
setting (PWM output) (Un\G1302, Un\G1303), and turn on CH1 Cam switch function/PWM output start command (Y08)
again.
Number Description
1)
Perform the following operation when CH1 Cam switch function/PWM output start command (Y08) is turned on:
• Latch the values in CH1 PWM output assignment (Un\G1300), CH1 On width setting (PWM output) (Un\G1302, Un\G1303),
and CH1 Cycle setting (PWM output) (Un\G1304, Un\G1305). (The change of the setting values during the PWM output is
ignored.)
• The PWM waveform is output from one of the coincidence output 1 to 8 terminal (EQU1 to EQU8) based on the settings.
(The PWM waveform is output starting with OFF.)
CH1 Cam switch function execution/PWM output (X08) turns on.
2)
Based on the latched settings, the PWM waveform continues to be output until CH1 Cam switch function/PWM output start
command (Y08) is turned off.
3)
CH1 Cam switch function execution/PWM output (X08) turns off and the coincidence output 1 to 8 terminal (EQU 1 to EQU8) is
turned off by turning off CH1 Cam switch function/PWM output start command (Y08).
