The number of divisions and upper limit output limiter
Configure the setting to divide the timing ("Peak current suppression control group setting" of "Peak current suppression
setting" in "Application Setting") in the setting mode ('Setting/operation mode status' (X1): OFF). Turn ON and OFF 'Setting
change command' (YB) to enable the setting. At the timing when the setting is enabled, "Upper limit output limiter" of "Limiter
setting" in "Application Setting" is automatically set according to the number of divisions.

"Lower limit output limiter" of "Limiter setting" in "Application Setting" is set to 0.0%.
The following shows the timing when the upper limit output limiter and lower limit output limiter are output by the peak current
suppression function.
• At power-ON
• When the CPU module is turned from STOP to RUN
• When the number of divisions is changed
When using this function, set a single value for the control output cycles of target channels.
When the parameter settings of the channels are different, an error does not occur.
• "Control output cycle setting" of "Control basic parameters" in "Application Setting"
The module operates with the value (%) of "Upper limit output limiter" of "Limiter setting" in "Application
Setting" that is automatically set when this function is used.
