∗1 The signal assigned to each of these terminals can be changed to the reset signal, etc. using the input terminal assignment function ( Pr.178 to Pr.182 ).
∗2 To use terminals PC and SD for a 24 VDC power supply, check the wiring for an incorrect short of these terminals.
∗3
Terminal input specifications can be changed by analog input specification switchover ( Pr.73 , Pr.267 ). To input voltage via terminal 4, set the voltage/
current input switch to "V" position. To input current (4 to 20 mA), set it to "I" position (initial setting).
∗4 It is recommended to use a 2 W 1 k Ω potentiometer when the frequency setting is frequently changed.
∗5 The function of these terminals can be changed with the output terminal assignment ( Pr.195 ).
