YASKAWA SIEPYEULA5001C LA500 Technical Manual 57
*2 To set the MFDI power supply (Sinking/Sourcing Mode or internal/external power supply), install or remove a jumper between
terminals SC-SP or SC-SN depending on the application.
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.
• Sinking Mode, Internal power supply: Install the jumper to close the circuit between terminals SC-SP.
NOTICE: Damage to Equipment. Do not close the circuit between terminals SC-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.
• Sourcing Mode, Internal power supply: Install the jumper to close the circuit between terminals SC-SN.
NOTICE: Damage to Equipment. Do not close the circuit between terminals SC-SP. If you close the circuits between
terminals SC-SP and terminals SC-SN at the same time, it will cause damage to the drive.
• External power supply: Remove the jumper from the MFDI terminals. It is not necessary to close the circuit between terminals SC-
SP and terminals SC-SN.
*3 The maximum output current capacity for terminal +V on the control circuit is 20 mA.
NOTICE: Damage to Equipment. Do not install a jumper between terminals +V and AC. A closed circuit between these
terminals will cause damage to the drive.
*4 Do not ground the control circuit terminals AC or connect them to the drive chassis.
NOTICE: Do not ground the AC control circuit terminals and only connect the AC terminals according to the product
instructions. If you connect the AC terminals incorrectly, it can cause damage to the drive.
*5 Do not connect terminals PS and AC inversely. Failure to obey will cause damage to the drive.
*6 To use the internal power supply with the Safe Disable input, use sourcing mode.
*7 Use multi-function analog monitor outputs with analog frequency meters, ammeters, voltmeters, and wattmeters. Do not use monitor
outputs with feedback-type signal devices.
*8 Disconnect the wire jumpers between H1 and HC and H2 and HC to use the Safe Disable input.
◆ Control Circuit Terminal Block Functions
Hx-xx parameters set functions for the multi-function input and output terminals.
WARNING! Sudden Movement Hazard. Correctly wire and test all control circuits to make sure that the control circuits operate
correctly. If you use a drive that has incorrect control circuit wiring or operation, it can cause death or serious injury.
NOTICE: Damage to Equipment. Do not energize and de-energize the drive more frequently than one time each 30 minutes. If
you frequently energize and de-energize the drive, it can cause drive failure.
