◆ Set Sinking Mode/Sourcing Mode
Close the circuit between terminals SC-SP and SC-SN 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: Damage to Equipment. Do not close the circuit between terminals SP-SN. If you close the circuits between terminals SC-
SP and terminals SC-SN at the same time, it will cause damage to the drive.
