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.
- 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
In this example, M0 is used as the head input for mode specification.

When inputs do not have
consecutive device numbers
Example:

X033: Stepping operation mode
X040: Cycle operation mode
X032: Continuous operation mode
X034: Zero return start
X026: Automatic mode start
X041: Stop
When only the continuous
operation mode and zero return
operation mode are used
Example:
X030: Zero return operation mode
X031: Continuous operation mode
X032: Automatic mode start zero
return start
X033: Stop
When only the continuous
operation mode and individual
operation mode are used
Example:
X030: Individual operation mode
X031: Continuous operation mode
X032: Automatic mode start
X033: Stop
