4.3 Comparison Output Function 4.3.4 Cam switch function
(7) Signal timing of the cam switch function
The following figure shows signal timing of the cam switch function. Note that the coincidence output 1 is
assigned to CH1.
The cam switch function can be performed regardless of the ON/OFF status of CH1 Count enable command (Y06).
Number Description
1)
When CH1 Cam switch function/PWM output start command (Y08) is turned on (OFFON), the step setting is latched and
CH1 Cam switch function execution/PWM output (X08) turns on. (If the setting value of the step setting is changed while the
cam switch function is in operation, the change is ignored.)
2) The cam switch function operates when CH1 Cam switch function execution/PWM output (X08) turns on.
3)
CH1 Present value (Un\G1050, Un\G1051) and the step setting is compared and the result is output to coincidence output 1
(X10).
If CH1 Coincidence output enable command (Y02) is off, the result is not output to the coincidence output 1 terminal (EQU1).
4) To output signals from the coincidence output 1 terminal (EQU1), turn on CH1 Coincidence output enable command (Y02).
5)
When CH1 Cam switch function/PWM output start command (Y08) is turned off (ONOFF), CH1 Cam switch function
execution/PWM output (X08), coincidence output 1 (X10), and the coincidence output 1 terminal (EQU1) turn off.
