In order to use IST command, inputs of the following serial numbers must be assigned in the mode inputs.
If the numbers are not serial, or modes are partly omitted, the array is modified by using auxiliary relays as
shown below, which is used as the mode designation beginning input.
- X020: Individual operation

- X022: Stepping
- X023: One-cycle operation
- X024: Continuous operation
- X025: Return home start
- X026: Automatic start
