*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 when the frequency setting signal is changed frequently.
*7 Remove the jumper between terminals PR and PX to connect the brake resistor. (FR-A820-00490(7.5K) or lower and FR-A840-00250(7.5K) or
lower).
*8 Connect a brake resistor across terminals P/+ (P3) and PR. (Terminal PR is equipped in the FR-A820-00046(0.4K) to 01250(22K), and FR-A840-
00023(0.4K) to 01800(55K).) Install a thermal relay to prevent overheating and damage of brake resistors. (Refer to
*9 Do not connect the DC power supply (under DC feeding mode) to terminal P3.
*10 The function of these terminals can be changed using the Output terminal function selection (Pr.195 or Pr.196). (Refer to
*11 The function of these terminals can be changed using the Output terminal function selection (Pr.190 to Pr.194). (Refer to
*12 Terminal FM can be used to output pulse trains as open collector output by setting Pr.291.
*13 Not required when calibrating the scale with the operation panel.
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.
