◆ 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.
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 3.23 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.
WARNING! Fire Hazard. 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.
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.
