Classification
Symbol Name Functional description
[C1]
Analog setting
current input
(C1 function)
(1) The frequency is commanded according to the external
analog current input.
• 4 to 20 mA DC/0 to 100%, 0 to 20 mA DC/0 to 100% *4
(Normal operation)
• 20 to 4 mA DC/0 to 100%, 20 to 0 mA DC/0 to 100% *4
(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: 250 Ω
* The maximum input is +30 mA DC, however, the current
larger than +20 mA DC is handled as +20 mA DC.
Analog input
[V2]
Analog setting
voltage input
(V2 function)
(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
[V2] requires setting function code C45 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.
