Note 1: OC indicates the open collector. LD indicates the line driver.
Note 2: For Input 4 and Input 5, function assignment can be changed in parameter setting. For details,
refer to 2-1.
Do not connect the pins with “-” in the Signal column to the external
device.
If you do, failure may occur because it is connected to the internal circuit.
