Input Terminals - YASKAWA GA800 Series Installation & Primary Operation

10 Drive Start-Up Procedure
NOTICE
Damage to Equipment. The drive can fail if users frequently turn the drive ON and OFF with the MC on the power
source side to Run and Stop the drive. Incorrect operation can decrease the service life of the relay contacts and electrolytic
capacitors. If you frequently use the magnetic contactor on the power source side to Run and Stop the drive, it can cause drive
failure.

Note:
Install the wire jumpers between terminals SC-SP and SC-SN to set the MFDI power supply
(sinking/sourcing mode or internal/external power supply).
• Sinking Mode: Install a jumper between terminals SC and SP.
• Sourcing Mode: Install a jumper between terminals SC and SN.
• External power supply: No jumper necessary between terminals SC-SN and terminals SC-SP.
MFDI power supply, 24 V (maximum 150 mA)
closed circuit between these terminals will cause damage to the drive.
Remove the jumper between terminals H1-HC and H2-HC to use the Safe Disable input.
• 24 V, 6 mA
