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). (Refer to
To use terminals PC and SD for a 24 VDC power supply, check the wiring for an incorrect short of these terminals.
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).
It is recommended to use a 2 W 1 kΩ potentiometer when the frequency setting is frequently changed.
The function of these terminals can be changed with the output terminal assignment (Pr.195). (Refer to
• To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, keep the
cables of the main circuit for input and output separated.
• After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the inverter.
• Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.
• The output of the single-phase power input model is three-phase 200V.
