Wiring the Control Circuit Terminal

WARNING! Electrical Shock Hazard. Do not remove covers or touch circuit boards while the drive is energized. If you touch the

internal components of an energized drive, it can cause serious injury or death.

NOTICE: Do not let wire shields touch other signal lines or equipment. Insulate the wire shields with electrical tape or shrink tubing.

If you do not insulate the wire shields, it can cause a short circuit and damage the drive.

• 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, +3) 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.

• 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.

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.

NOTICE: When you remove the LED Status Board from the drive bracket, make sure that you temporarily install it in the

holding position provided on the drive. If you cause damage to the LED status ring board, the LEDs will not function

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.
