1.3 Standard connection diagram and terminal
specifications
1.3.1 Internal block diagram
(1) FR-A700
*1 A common mode choke is provided for the 55K or less.
*2 For the 75K or more, a jumper across terminal P1-P/
+
is not provided. Always connect a DC reactor provided.
When a DC reactor is connected to the 55K or less, remove the jumper across P1-P/
+
.
*3 A relay is used for the 200V class 11K and 30K to 90K and 400V class 11K, 15K and 110K to 500K.
*4 The 200V class 0.4K and 0.75K are not provided with the EMC filter ON/OFF connector.
*5 To supply power to the control circuit separately, remove the jumper across R/L1-R1/L11 and S/L2-S1/L21.
*6 Terminal function can be changed using [ Pr. 178 to Pr. 189 Input terminal selection ].
*7 Terminal input specifications can be changed by analog input specifications switchover ([ Pr. 73, Pr. 267 ]). Note that the
current at terminal 2 and 4 is always 4 to 20mA when the voltage/current input switch is set to ON.
Terminal 2 : Initial value 0 to 5VDC (can be changed to 0 to 10VDC, 4 to 20mADC)
Terminal 4 : Initial value 4 to 20mADC (can be changed to 0 to 5VDC, 0 to 10VDC)
Terminal 1 : Initial value 0 to 10VDC (can be changed to 0 to 5VDC)
*8 It is recommended to use 2W1k when the frequency setting signal is changed frequently.
*9 Remove the jumper across terminal PR-PX when connecting a brake resistor. (0.4K to 7.5K)
Terminal PR is provided for the 0.4K to 22K.
*10 The built-in brake resistor is provided for the 7.5K or less. A brake transistor is provided for the 22K or less.
*11 A CN8 connector is provided for the 75K or more.
*12 Terminal function can be changed using [
Pr. 190 to Pr. 196 Output terminal selection ].
*13 It is not necessary when calibrating the meter from the operation panel.
