Frequency setting by analog input (terminal 2, 4) Parameter
6 - 178
Selection of analog input specifications
For the terminal 2 for analog voltage input, 0 to 5 V (initial value) or 0 to 10 V can be selected. Either
voltage input (0 to 5 V, 0 to 10 V) or current input (4 to 20 mA initial value) can be selected for terminal
4 used for analog input. Change the input specifications by setting Pr. 73 and Pr. 267 and voltage/cur-
rent input switch.
Rated specifications of terminal 4 change according to the voltage/current input switch setting:
Voltage input: Input resistance 10 k 1 k , maximum permissible input voltage 20 V DC
Current input: Input resistance 233 5 , maximum permissible current 30 mA

CAUTION:
Set Pr. 267 and a voltage/current input switch correctly, then input an analog signal in accord-
ance with the setting. Incorrect setting as in the table below could cause component damage.
Incorrect settings other than below can cause abnormal operation.
