Note:
  • Isolate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, 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.

  • When you use a photocoupler output/screw clamp terminal board type control circuit board, isolate contact output terminals MA, MB, MC and M1-M4 from other control circuit wiring. If contact output terminal wiring is adjacent to other control circuit wiring, it can cause incorrect operation of the drive and equipment from electrical interference.

  • When you use a relay output/screw clamp terminal board type control circuit board, isolate wiring for contact output terminals MA, MB, MC and M1-M6 from other control circuit wiring. If contact output terminal wiring is adjacent to other control circuit wiring, it can cause incorrect operation of the drive and equipment from electrical interference.

  • 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.

Correctly ground the drive terminals and complete main circuit wiring before you wire the control circuit. Remove the keypad and front cover.

  1. Push in on the tabs on the both sides of the LED status ring board to release the board from the bracket. Pull the board forward to remove it.
    Note:

    You can temporarily store the LED status ring board with the temporary placement holes on the drive. The location of the temporary placement holes is different on different drive models.

  2. Refer to the figure and wire the control circuit.
    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 4. 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 keep the ends from fraying.
    • 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:
    • 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 5 for information to prepare terminal ends of the shielded wire.

    • Prepare the wire ends of shielded twisted-pair wires as shown in Figure 5 to use an analog reference from an external frequency setting potentiometer to set the frequency. Connect the shield to terminal E (G) of the drive.

    Figure 5. Prepare the Ends of Shielded Wire
    • Connect the shield to terminal E (G) of the drive.
    • Sheath
    • Insulate with electrical tape or shrink tubing.
  3. Put the wires through the clearance in the wiring cover.
    Figure 6. Control Circuit Wiring
  4. On drive models 4810 to 4H12, wire the drive control circuit as shown in Figure 7 or Figure 8.
    Note:

    When you wire the control circuit wiring outside the drive, use the slits on the sides of the drive and safety the wires with cable ties. You can wire on either the left or right side.
