◆ 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: Do not close the circuit between terminals SP and SN. Failure to obey will cause damage to the drive.
Mode Internal Power Supply (Terminal SN-SP) External Power 24 V
