1
Connect a 24 V power supply to terminals PS-AC to operate the control circuit while the main circuit power supply is OFF.
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 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. 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 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.
11
Connect a 24 V Control power input supply to terminals PS-AC to operate the control circuit while the main circuit power supply is OFF.
