(Note 5) Normally no need to be connected. Use these terminals when the inverter is equipped with a high power factor
PWM converter with a regenerative facility.
(Note 6) You can select the frequency command source either electronically by supplying a DC voltage signal (within
the range of 0 to 10 V, 0 to 5 V, or 1 to 5 V) between terminals [12] and [11], or manually by connecting a
frequency command potentiometer to terminals [13], [12], and [11].
(Note 7) For the wiring of the control circuit, use shielded or twisted wires. When using shielded wires, connect the
shields to earth. To prevent malfunction due to noise, keep the control circuit wires as far away as possible
from the main circuit wires (recommended distance: 10 cm or longer), and never put them in the same wire
duct. Where a control circuit wire needs to cross a main circuit wire, route them so that they meet at right
angles.
