*5
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)
*6
It is recommended to use 2 W 1 kΩ when the frequency setting signal is changed frequently.
*7
The function of these terminals can be changed using the Output terminal function selection (Pr.195 or Pr.196).
*8
The function of these terminals can be changed using the Output terminal function selection (Pr.190 to Pr.194).
*9
No function is assigned in the initial setting. Use Pr.192 for function assignment.
*10 Terminal FM can be used to output pulse trains as open collector output by setting Pr.291.
*11 Not required when calibrating the scale with the operation panel.
*12 The option connector 2 cannot be used because the Ethernet board is installed in the initial status. The Ethernet board must be removed to install
a plug-in option to the option connector 2. (However, Ethernet communication is disabled in that case.)
*13 The Ethernet board must be removed to install the PROFIsafe communication option (A8SPRS).
*14 When the FR-A8NCG-S is installed, other options can be connected to the connectors 2 and 3. When the A8SPRS is installed, other options can
be connected to the connector 3. For the options available when the safety communication option is installed, refer to
*15 Do not remove the jumpers from terminals S1, S2, and SIC. Do not use terminals S1, S2, SIC, and So (SO).
NOTE
• 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
malfunction.
