Classification
Symbol Name Functional description
[13]
Power supply for
the potentiometer
Power supply (+10 VDC) for frequency command potentiometer
(Potentiometer: 1 to 5 kΩ)
The potentiometer of 1/2 W rating or more should be connected.
Analog input
[12]
Analog setting
voltage input
(1) The frequency is commanded according to the external
analog voltage input.
•0 to ±10 VDC/0 to ±100% (Normal operation)
•+10 to 0 VDC/0 to 100% (Inverse operation)
(2) In addition to frequency setting, PID command, PID
feedback signal, auxiliary frequency command setting, ratio
setting, torque limiter level setting, torque command value*1,
*2/torque current command value*1, *2,
speed limit*4, or analog input monitor can be assigned to
this terminal.
(3) Hardware specifications
* Input impedance: 22 kΩ
* The maximum input is ±15 VDC, however, the voltage
higher than ±10 VDC is handled as ±10 VDC.
* Inputting a bipolar analog voltage (0 to ±10 VDC) to
terminal [12] requires setting function code C35 to "0."
*1 Available under vector control without speed sensor.
*2 Available under vector control with speed sensor. (PG option required)
*4 Available in inverters having a ROM version 3600 or later.
