(1) Selection of analog input selection
⋅ 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.
Change parameters (Pr.73, Pr.267) and a voltage/current input switch (switch 1, 2) to change input specifications.

⋅ Rated specifications of terminal 2 and 4 change according to the voltage/current input switch setting.
Voltage input:
Input resistance 10kΩ ± 1kΩ, Maximum permissible voltage 20VDC
Current input:
Input resistance 245Ω ± 5Ω, Maximum permissible current 30mA
CAUTION
⋅ Set Pr.73, Pr.267, and a voltage/current input switch correctly, then input an analog signal in accordance with the
setting. Incorrect setting as in the table below could cause component damage. Incorrect settings other than
below can cause abnormal operation.

This could cause component damage to the analog signal output circuit of signal
output devices. (electrical load in the analog signal output circuit of signal output
devices increases)
This could cause component damage of the inverter signal input circuit. (output
power in the analog signal output circuit of signal output devices increases)
