Mitsubishi Electric FR-F800 Series Instruction Manual page 49

*1 For the FR-F820-03160(75K) or higher and the FR-F840-01800(75K) or higher, always connect the DC reactor option FR-HEL. Refer to
638 to select the right DC reactor according to the applicable motor capacity.
To connect a DC reactor to the FR-F820-02330(55K) or lower or the FR-F840-01160(55K) or lower, remove a jumper installed across terminals
P1 and P/+, before installing the DC reactor. (The jumper is not installed for the FR-F820-03160(75K) or higher and the FR-F840-01800(75K) or
higher.)
*2 When using separate power supply for the control circuit, remove the jumper between R1/L11 and S1/L21.
*3 The function of these terminals can be changed using the Input terminal function selection (Pr.178 to Pr.189). (Refer to
*4 Terminal JOG is also used as a pulse train input terminal. Use Pr.291 to choose JOG or pulse.
*5 Terminal input specifications can be changed by analog input specification switchover (Pr.73, Pr.267). To input a voltage, set the corresponding
switch of the voltage/current input selection switch assembly to the OFF position. To input a current, set the switch to the ON position. Terminals
10 and 2 are also used as a PTC input terminal (Pr.561). (Refer to
*6 It is recommended to use 2 W 1 kΩ potentiometer when the frequency setting signal is changed frequently.
*7 Do not use terminals PR, PX, and P3. Whether a jumper is provided across the terminals depends on the inverter model. (Refer to
*8 The function of these terminals can be changed using the Output terminal function selection (Pr.195 or Pr.196). (Refer to
*9 The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194). (Refer to
*10 No function is assigned in the initial setting. Assign the function using Pr.186 CS terminal function selection. (Refer to
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.
