CS/CJ/NSJ Series Instructions Reference Manual (W474)
All of these parameters can be changed at the same time. All parameters must be specified even
when changing only one of them.
If invalid parameters are specified, an instruction error will occur and the parameters will not be
changed. If an origin search or origin return is executed after such an error occurs, the previous
parameters will be used in the operation.
z Changing the Maximum Ring Value (C = 0006 Hex) (CJ2M Only)
If C is 0006 hex, INI(880) changes the maximum ring value of the high-speed counter during opera-
tion. The initial value for the maximum ring value is set in the PLC Setup. INI(880) is used to tempo-
rarily change the maximum ring value in an application.
The following restrictions apply.
• The maximum ring value can be changed only when the comparison operation is stopped.
• CTBL(882) must be executed again to restart the comparison operation after the maximum ring
value is changed.
Note The settings in the PLC Setup are not changed. When power is turned ON, the settings in the PLC Setup will
be used.
When the maximum ring value is changed, the PV of the high-speed counter will be cleared to zero.
Example Programming
Example: Changing the PV for Pulse Output (C = 0002 Hex)
When CIO 0.00 turns ON in the following example, INI(880) changes the PV of pulse output 0 to 0.
Example: Stopping Pulse Output (C = 0003 Hex)
When CIO 0.00 turns ON in the following example, SPED(885) starts outputting pulses from pulse
output 0 in Continuous Mode at 500 pps. When CIO 0.01 turns ON, pulse output is stopped by INI(880).
