5.2 Wiring Precautions

Make sure of the following when wiring.

• Separate the control signal wires (terminal blocks TA1 and TA2) of the PG-X2 card from the main

circuit wires and other power cables.

• Use a shielded wire to connect the encoder (PG). Connect the wires as shown in Fig. 5 to prevent

noise interference. The wire distance must be 328 ft. (100 m) or less.

• To prevent noise, use shielded wire and separate from heavy current circuits (200 VAC or greater)

or relay drive circuits. (Wire length to the PG connector must be 328 ft. (100 m) or less.)

• If the PG signal is affected by noise, disconnect the grounding lead wire (E) from the grounding

terminal (G5: 12 (G), G7 or F7: E (G)) of the control board of the Inverter. Alternatively, change

the location of the shielded sheath connection.

• The recommended tightening torque is 0.22 to 0.25 Nxm.
