Step Number Limit (f5)
With the H8PS, up to 10 steps can be set to turn the output ON/OFF
10 times for each cam. The number of steps that can be set,
however, can be restricted to prevent programming from being added
through operating mistakes. Settings can be made for all cams at
once or each cam individually. The default setting for the Step
Number Limit is 10 steps for all cams.
Example: Limiting the Number of Steps to 2 for All Cams
Collectively.
The maximum number of steps to be set is set using the F5 menu in
the Function Setting Mode.
