(3) Minimum setting width of the ON/OFF status
To output the ON/OFF signal according to the setting, set the value of each step No. so that the following formula
is satisfied.
(Input pulse speed [pps]
• Allowable time: (ΔT
• ◆: Cam switch output No. (1 to 16)
• i: Step No. (1 to 15)
For ΔT
, refer to Page 283, Appendix 4.

*1
Either of the output response time for switching on from off or that for switching off from on, whichever is longer
When the input pulse speed is 10kpps and the output response time of the extension output module is
Ex.
1.5ms
Allowable time: (0.5ms × 2) + 1.5ms = 2.5ms
Setting width of the ON/OFF status: (10 × 10
Therefore, set the difference between the values of Cam switch function, step No.i setting (Output ◆) and
Cam switch function, step No.i + 1 setting (Output ◆) to 25 or more.
(4) Timing of when the cam switch function setting is enabled
The following table shows the timing of when the cam switch function is enabled.
CH Cam switch execute command (RY26, RY3E) is enabled while Initial data processing request flag (RX8) is
off or Initial data setting completion flag (RX9) is off.

For all of Cam switch function, step type (Output ◆), Cam switch function, number of steps (Output ◆), and Cam switch
function, step No.i setting (Output ◆) of cam switch output ◆ that is not used, set the default (0). When a value other than the
default is set, output may be turned on when the cam switch function is performed.
In addition, when a value other than the default value is backed up to the nonvolatile memory by turning off then on Initial
data setting request flag (RY9), the setting in the nonvolatile memory also must be set to the default. If the setting in the
nonvolatile memory is not the default, the above setting item becomes the backed up value when the module power supply
is turned off then on or the module returns from the remote reset.
