Control Circuit Terminal Block Functions - YASKAWA GA800 Series Technical Reference

*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: Do not close the circuit between terminals SP-SN. A closed circuit between these terminals 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 terminals SC-
SP and terminals SC-SN, 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 terminals SC-
SP and terminals SC-SN, 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 output current capacity of the +V and -V terminals on the control circuit is 20 mA.
NOTICE: Do not install a jumper between terminals +V, -V, and AC. A closed circuit between these terminals will cause
damage to the drive.
*4 Set DIP switches S1-1 to S1-3 to select between a voltage or current input signal to terminals A1 to A3. The default setting for S1-1 and
S1-3 is voltage input ("V" side). The default setting for S1-2 is current input ("I" side).
*5 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.
*6 Do not connect terminals PS and AC inversely. Failure to obey will cause damage to the drive.
*7 Set DIP switch S2 to the ON position to enable the termination resistor in the last drive when you use MEMOBUS/Modbus
communications.
*8 To use the internal power supply with the Safe Disable input, use sourcing mode.
*9 Disconnect the wire jumpers between H1 and HC and H2 and HC to use the Safe Disable input.
*10 Use multi-function analog monitor outputs with analog frequency meters, ammeters, voltmeters, and wattmeters. Do not use monitor
outputs with feedback-type signal devices.

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.
WARNING! Sudden Movement Hazard. Check the I/O signals and the external sequences for the drive before you set the
Application Preset function. When you set the Application Preset function (A1-06 ≠ 0), it changes the I/O terminal functions for the
drive and it can cause equipment to operate unusually. This can cause serious injury or death.
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.
