Loosen the terminal screw and insert the cable into the terminal.

Screw size

Tightening torque

0.22 Nm to 0.25 Nm

NOTE

• Undertightening may cause cable disconnection or malfunction. Overtightening can cause a short circuit or malfunction due

to damage to the screw or unit.

• When wiring the RS-485 terminals on the inverter with the plug-in options installed, be careful not to let RS-485 cables touch

the option circuit boards and the inverter circuit board. This is to prevent a malfunction due to electromagnetic noises.

• When one position detector is shared between FR-A8AP and CNC (computerized numerical controller), its output signal

should be connected as shown below. In this case, the wiring length between FR-A8AP and CNC should be as short as

possible, within 5 m.

CAUTION

• Do not use empty terminals as junction terminals because they are used internally used by the option. Doing so may damage the plug-in

option.

• After wiring, do not leave wire offcuts in the inverter. Doing so may cause a fault, failure or malfunction.
