The X10 signal (NC contact input specification) is assigned to the terminal MRS in the initial setting. Set Pr.599 = "0" to change the input
specification of the X10 signal to NO contact.
Terminal input specifications can be changed by analog input specification switchover (Pr.73, Pr.267). To input voltage (0 to 5 V/0 to 10 V), set
the voltage/current input switch OFF. To input current (4 to 20 mA), set the voltage/current input switch ON. Terminals 10 and 2 are also used as
a PTC input terminal. (Pr.561)
It is recommended to use 2 W 1 kΩ when the frequency setting signal is changed frequently.
The function of these terminals can be changed using the Output terminal function selection (Pr.195 or Pr.196).
The function of these terminals can be changed using the Output terminal function selection (Pr.190 to Pr.194).
No function is assigned in the initial setting. Use Pr.192 to assign a function to the terminal.
• 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 a fault, 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 switches of the voltage/current input selection switch assembly correctly. Incorrect setting may cause a fault, failure or
