Using Event Inputs Section 4-5
4-5-2 How to Use the Multi-SP Function
The multi-SP function allows you to set up to four set points (SP 0 to 3) in the
adjustment level. The set point can be switched by operating the keys on the
front panel or by using external input signals (event inputs).
Using Event Inputs
■ Two Event Inputs: Event Inputs 1 and 2
The following tables show the relationship between the ON/OFF combinations
of event inputs 1 and 2 and the selected set points.
Number of Multi-SP Uses = 1
Number of Multi-SP Uses = 2
Using Key Operations You can select any of the set points 0 to 3 by changing the set value of the
Multi-SP Uses parameter. The Multi-SP Uses parameter display conditions
are as follows:
• If the Controller does not support event inputs, the Multi-SP Uses param-
eter must be set to ON.
• If the Controller supports event inputs, the Number of Multi-SP Uses
parameter must be set to 0 and the Multi-SP Uses parameter must be set
to ON.
The following table shows the relationship between the Multi-SP Uses param-
eter set value and the selected set point.
Note The set point can also be switched using communications.
