◆ Set Sinking Mode/Sourcing Mode
Close the circuit between terminals DIC-D24V and DIC-D0V to set the sinking mode/sourcing mode and the
internal/external power supply for the MFDI terminals. The default setting for the drive is internal power supply
sinking mode.
NOTICE: Do not close the circuit between terminals D24V and D0V. Failure to obey will cause damage to the drive.
