[ 3 ] Description of terminal functions (control circuit terminal)
Generally, the insulation for control signal lines is not enhanced. When the control signal lines come into direct
contact with the main circuit live section, the insulation cover may be damaged. High voltage of the main circuit
may be applied on the control signal lines, so exercise caution such that the main circuit live sections do not
contact the control signal lines.
Risk of accidents and risk of electric shock exist.
Noise is generated by the inverter, motor, and wiring.
Exercise caution to prevent malfunction of peripheral sensors and instruments.
Risk of accidents exists.
Table 2.2-30 shows the functional explanations for the control circuit terminals. The connection method of the
control circuit terminals differs depending on the functional code setting matching the purpose of inverter operation.
Properly wire such that the impact of noise generated by the main circuit wiring is reduced.

Analog input
[13] Power supply
for the
potentiometer
The terminal is used for the power supply (DC+10 V 10 mA Max) for the external frequency
command potentiometer (variable resistor: 1 to 5 kΩ).
Connect variable resistors larger than 1/2 W.
[12] Analog setup
voltage input
(1) Frequency is set up according to the external analog voltage input command value.
Normal operation
• DC0 to +10 V/0 to 100(%) (DC0 to +5 V/0 to 100%)
• DC0 to ±10 V/0 to ±100(%) (DC0 to ±5 V/0 to ±100%)
Reverse operation
• DC+10 to 0V/0 to 100(%) (DC+5 to 0 V/0 to 100%)
• DC±10 to 0V/0 to ±100(%) (DC±5 to 0V/0 to ±100%)
(2) The terminal can be assigned to PID command, feedback signal of PID control, auxiliary
frequency setup, ratio setup, torque limit setup, and analog input monitor aside from the
frequency setup by analog input.
(3) Hardware specification
* Input impedance: 22 (kΩ)
* Up to DC±15 V can be input. However, input exceeding DC±10 V will be recognized as
DC±10 V.
[C1] Analog setup
current input
(C1 function)
(1) Frequency is set up according to the external analog current input command value.
Normal operation
• DC4 to 20 mA/0 to 100(%)/-100% to 0 to 100%
• DC0 to 20 mA/0 to 100(%)/-100% to 0 to 100%
Reverse operation
• DC20 to 4 mA/0 to 100(%)/-100% to 0 to 100%
• DC20 to 0 mA/0 to 100(%)/-100% to 0 to 100%
(2) The terminal can be assigned to PID command, feedback signal of PID control, auxiliary
frequency setup, ratio setup, torque limit setup, and analog input monitor aside from the
frequency setup by analog input.
(3) Hardware specification
* Input impedance: 250 (Ω)
* Up to DC 30 mA can be input. However, input exceeding DC 20 mA will be recognized as
DC 20 mA.
