*1 Terminal functions can be selected using Pr.178 to Pr.189 (Input terminal function selection).
*2 Set Pr.73, Pr.267, and the voltage/current input switch correctly, then input an analog signal in accordance with the setting.
Applying a voltage with the switch ON (current input is selected) or applying a current with the switch OFF (voltage input is selected) could cause
component damage of the inverter or analog circuits of output devices. (Refer to the Instruction Manual (Detailed).)
Terminal name
When connecting the frequency setting potentiometer at an initial
status, connect it to terminal 10.
Change the input specifications of terminal 2 using Pr.73 when
connecting it to terminal 10E.
Inputting 0 to 5 VDC (or 0 to 10 V, 0 to 20 mA) provides the
maximum output frequency at 5 V (10 V, 20 mA) and makes input
and output proportional. Use Pr.73 to switch among input 0 to 5
VDC (initial setting), 0 to 10 VDC, and 0 to 20 mA. Set the
voltage/current input switch in the ON position to select current
input (0 to 20 mA).
Inputting 4 to 20 mADC (or 0 to 5 V, 0 to 10 V) provides the
maximum output frequency at 20 mA and makes input and output
proportional. This input signal is valid only when the AU signal is
ON (terminal 2 input is invalid). Use Pr.267 to switch among input
4 to 20 mA (initial setting), 0 to 5 VDC, and 0 to 10 VDC. Set the
voltage/current input switch in the OFF position to select voltage
input (0 to 5 V / 0 to 10 V).
functions.
Input 0 to ±5 VDC or 0 to ±10 VDC to add this signal to the
frequency setting signal input via terminal 2 or 4. Use Pr.73 to
switch between input 0 to ±5 VDC and 0 to ±10 VDC (initial
setting). Use Pr.868 to switch terminal functions.
For receiving PTC thermistor outputs.
When PTC thermistor is valid (Pr.561 ≠ "9999"), terminal 2 is not
available for frequency setting.
For connecting a 24 V external power supply.
If a 24 V external power supply is connected, power is supplied
to the control circuit while the main power circuit is OFF.
