3. Assignment of mode selection inputs
For using IST instruction, it is necessary to assign inputs having consecutive device numbers as shown below for
mode inputs.
When using non-consecutive inputs or omitting some modes, change the layout by using an auxiliary relay as the
head input for mode specification as shown in the figure below.
mode inputs.
When using non-consecutive inputs or omitting some modes, change the layout by using an auxiliary relay as the
head input for mode specification as shown in the figure below.
- X020: Individual operation mode
- X021: Zero return operation mode
- X022: Stepping operation mode
- X023: Cycle operation mode
- X024: Continuous operation
- X025: Zero return start
- X026: Automatic mode start
- X027: Stop
- X021: Zero return operation mode
- X022: Stepping operation mode
- X023: Cycle operation mode
- X024: Continuous operation
- X025: Zero return start
- X026: Automatic mode start
- X027: Stop
In this example, M0 is used as the head input for mode specification.
