Wire the drive control circuit as shown in Figure 1 or Figure 2.

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.

  • Sinking Mode, Internal power supply: Install the jumper to close the circuit between terminals SC-SP.

  • Sourcing Mode, Internal power supply: Install the jumper to close the circuit between terminals SC-SN.

  • 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.

The output current capacity of the +V and -V terminals on the control circuit is 20 mA.

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.
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.
