8.5 Detailed explanations of commands
Disabling/enabling I/O devices (DIO)
Inputs can be disabled regardless of the I/O device status. When inputs are disabled, the input signals (devices) are
recognized as follows. However, EM2 (Forced stop 2), LSP (Forward rotation stroke end), and LSN (Reverse rotation stroke
end) cannot be disabled.
Input devices
Input devices (excluding EM2, LSP, and LSN), external analog input signals, and pulse train inputs can be disabled or
enabled.
