2.14 Control Circuit Wiring
YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual 101
*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.
Do not close the circuit between terminals SC-SN. If you connect the wires to the incorrect terminals, it will cause damage to the
drive.
• Sourcing Mode, Internal power supply: Install the jumper to close the circuit between terminals SC-SN.
Do not close the circuit between terminals SC-SP. If you connect the wires to the incorrect terminals, 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 DIP switch S1 sets terminal A2 for voltage or current input. The default setting for S1 is current input (“I” side).
*5 Do not ground the control circuit terminals AC or connect them to the drive chassis. Failure to comply may cause malfunction or
failure
*6 Do not connect terminals PS and AC inversely. If you connect the wires to the incorrect terminals, it will cause damage to the drive.
*7 Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a 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. 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.
■ Input Terminals
Refer to
Table 2.15 for a list of input terminals and functions.
Text in parenthesis indicates the default setting for each multi-function output.
