NOTE
1 This is an IBM PC–compatible standard interface. Particular care should be paid to the
following points, however.
(1)Only two modes (720K/1.44M bytes) can be used.
(2)“DENSEL” is fixed to the low level.
(3)Not all commercially available floppy disk drives require both +12 V and +5 V DC. When
using a floppy disk drive which requires +12 V DC, pay careful attention to its power
requirements.
2 Since many commercially available floppy disk drives perform differently with any one given
personal computer, FANUC cannot guarantee all operations. Machine tool builders are
requested to confirm the compatibility of each drive, and the operations that are supported.
Also, be careful when using commercially available floppy disk drives because none offer
dust–proof or drip–proof properties.
3 The FDD–side interface shown above is merely an example. Each cable should be designed
according to the interface of the actual drive to be used.
