(common)
Frequency setting is available with 5VDC, 10VDC, 20mADC input and those combinations for external frequency command
setting.
Select the input signal with [
Pr. 73 Analog input selection
] from 5VDC, 10VDC, and 4 to 20mADC.
And set frequency for maximum input voltage or current with [ Pr. 125, 126 ].
Analog input
(1) Selection of analog input specifications
[ Pr. 73, 267 ]
1)
You can select the function that switches between
forward rotation and reverse rotation according to the
analog input terminal selection specifications, the
override function and the input signal polarity.
For the terminals 2, 4 used for analog input, voltage
input (0 to 5V, 0 to 10V) or current input (4 to 20mA)
can be selected.
The current at terminal 2 and 4 is always 4 to 20mA
when the voltage/current input switch is set to ON.
When turning ON the voltage/current input switch, set
input specifications of terminal to current input using
[
Pr. 73, 267 ].
Terminal 2, 4 is fixed for voltage input when the
voltage/current input switch is set to OFF. When
turning OFF the voltage/current input switch, set
input specifications of the terminal to voltage input
using [
Pr. 73, 267 ].
