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 10.13 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.
