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.
