The drive reads the terminal status one time. The drive immediately reads all changes to the terminal status.
This setting lets the drive quickly respond to changes in the sequence, but noise can cause malfunction.
1 : Double Scan
The drive reads the terminal status two times. The drive reads all changes to the terminal status two times to make
sure that the reading is the same.
