Wiring the Control Circuit Terminal

WARNING! Electrical Shock Hazard. Do not remove covers or touch circuit boards while the power is on. Failure to comply
could cause death or serious injury.
NOTICE: Separate 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 lines. Improper wiring practices could cause drive malfunction due to electrical interference.
NOTICE: Wire contact output terminals MA, MB, MC and M1-M4 with them isolated from other control circuit wiring. If wired
improperly, the drive and its equipment will malfunction or the drive may trip.
NOTICE: Use a class 2 power supply when connecting to the control terminals. Improper application of peripheral devices could
cause drive performance degradation due to improper power supply.
NOTICE: Insulate shields with tape or shrink tubing to prevent contact with other signal lines and equipment. Improper wiring
practices could cause drive or equipment malfunction due to short circuit.
NOTICE: Connect the shield of shielded cable to the appropriate ground terminal. Improper equipment grounding could cause
drive or equipment malfunction or nuisance trips.
Wire the control circuit only after terminals have been properly grounded and main circuit wiring is complete.
Remove the keypad and front cover.
1.
Press in on the hook of the LED status ring board to release it. Then, pull forward to remove the LED
status ring board.
Note:
• Take care so as not to damage the LED status ring board after it has been removed.
• The LED status ring board can be placed using the temporary placement holes. The location of the temporary placement
holes varies depending on the model.
A - Drive front
B - LED status ring board
2.
Refer to the following diagram and wire the control circuit.
WARNING! Fire Hazard. Tighten all terminal screws to the specified tightening torque. Loose or overtightened
connections could cause erroneous operation and damage to the terminal block or start a fire and cause death or
serious injury.
NOTICE: Use shielded twisted-pair cables as indicated to prevent operating faults. Improper wiring practices could
cause drive or equipment malfunction due to electrical interference.
