Wiring diagram (for unidirectional rotation)

• The motor revolving speed can be set from the speed setting knob on the panel.

• The thick continuous lines represent main circuit. Use conductor of size 0.75 mm

(AWG 18) or larger for the

main line.

• The thin continuous lines represent signal circuit. Use conductor of size 0.3 mm

or larger in the signal circuit.

When the distance from the tachometer generator (TG) is long, use shielded twisted pair cable.

Do not ground the shielding material.
