Table 3.4 Digital Inputs
Terminal Name (Default) Function (Signal Level)
DI1
MFDI selection 1
(ON: Forward run OFF: Stop)
Photocoupler
24 V, 6 mA
Note:
Install the wire jumpers between terminals DIC-D24V and DIC-D0V to set the MFDI power supply (sinking/
sourcing mode or internal/external power supply).
Sinking Mode: Install a jumper between terminals DIC and D24V.
NOTICE: Do not close the circuit between terminals DIC and D0V in Sinking
Mode. Failure to obey will cause damage to the drive.
Sourcing Mode: Install a jumper between terminals DIC and D0V.
NOTICE: Do not close the circuit between terminals DIC and D24V in Source
Mode. Failure to obey will cause damage to the drive.
External power supply: No jumper necessary between terminals DIC-D0Vand terminals DIC-D24V.

DI8
MFDI selection 8
(Baseblock command (N.O.))
D0V MFDI power supply 0 V
MFDI power supply, 24 V (maximum 150 mA)
NOTICE: Do not close the circuit between terminals D24V and D0V. Failure to
obey will cause damage to the drive.
