Note:

  • Use a Class 2 power supply to connect external power to the control terminals. If the power supply for peripheral devices is incorrect, it can cause a decrease in drive performance.

  • Connect the shield of shielded cable to the applicable ground terminal. Incorrect equipment grounding can cause drive or equipment malfunction from electrical interference.

  • Isolate wiring for contact output terminals MA, MB, MC, P1, C1, P2, and C2 from other control circuit wiring. Incorrect wiring procedures can cause the drive and connected equipment to malfunction and cause the drive to trip.

  • Isolate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, L/L1, N/L2, B1, B2, U/T1, V/T2, W/T3, -, +1, +2) and other high-power wiring. If control circuit wiring is adjacent to main circuit wiring, it can cause incorrect operation of the drive and equipment from electrical interference.

Wire the grounding terminal and main circuit terminals, then wire the control circuit terminals.

  1. Remove the front cover from the drive.

    You must remove the keypad to move Jumper S5.

    Figure 1. Remove the Front Cover
  2. Refer to the figure and wire the control circuit.

    Use a slotted screwdriver with a blade width of 2.5 mm (0.1 in) or less and thickness of 0.4 mm (0.01 in) or less.

    Note:

    • Use shielded, twisted-pair wires and ground the shield to the ground terminal of the drive. Incorrect equipment grounding can cause drive or equipment malfunction from electrical interference.

    • Do not use control circuit wiring that is longer than 50 m (164 ft) to supply the analog frequency reference from a remote source. If the control circuit wiring is too long, it can cause unsatisfactory system performance.

    Figure 2. Wiring Procedure for the Control Circuit
    • Loosen the screws and put the wire into the opening on the terminal block.
    • Wire with a crimp ferrule attached, or unsoldered wire with the core wires lightly twisted.
    • Pull back the shielding and lightly twist the end with your fingers to make sure that the ends do not fray.
    • When you do not use crimp ferrules, remove approximately 5.5 mm (0.21 in) of the covering at the end of the wire.
    • Blade width of 2.5 mm (0.1 in) or less
    • Blade thickness of 0.4 mm (0.01 in) or less
    Note:

    • It is easier to wire TB1-1 first, then TB1-2, then TB1-3.

    • Do not solder the core wire. Soldered wiring connections can become loose and cause the drive to malfunction.

    • Tighten all terminal screws to the correct tightening torque. Connections that are too loose or too tight can cause incorrect operation and damage to the drive. Incorrect connections can also cause death or serious injury from fire.

    • Refer to Figure 3 for information to prepare terminal ends of the shielded wire.

    • Prepare the wire ends of shielded twisted-pair wires as shown in Figure 3 to use an analog reference from an external frequency setting potentiometer to set the frequency. Connect the shield to the ground terminal of the drive.

    Figure 3. Prepare the Ends of Shielded Wire
    • Connect the shield to the ground terminal of the drive.
    • Sheath
    • Insulate with electrical tape or shrink tubing.
  3. Install the front cover.

    If you moved Jumper S5, attach the keypad before you attach the front cover.

    If you did not move Jumper S5, attach the front cover.

    Make sure that you do not pinch wires or signal lines between the front cover and the drive before you reattach the cover.
