3.3.2 Arrangement and wiring of control circuit terminals
A B C
Loosen the terminal screw and insert the cable into the
terminal.
Screw size: M3 (A, B, C terminals),
M2 (other than the above)
Tightening torque: 0.5N•m to 0.6N•m (A, B, C terminals)
CAUTION
Undertightening can cause cable
disconnection or malfunction. Overtightening
can cause a short circuit or malfunction due
to damage to the screw or unit.
Cable size: 0.3mm
Screwdriver: Small
(Tip thickness: 0.4mm/tip width: 2.5mm)

Bar terminal crimping tool: CRIMPFOX ZA3 (Phoenix Contact Co., Ltd.)
CAUTION
When using the bar terminal (without insulation sleeve), use care so that the
twisted wires do not come out.
3.3.3 Connection to RS-485 connector
(1) When connecting the parameter unit
Use the optional FR-CB2
operation from the operation panel is not accepted. (
(2) RS-485 communication
Using the RS-485 connector, you can perform communication operation from a
personal computer etc. By connecting the RS-485 connector to computers such as
personal computer and FA with a communication cable, you can run/monitor the
inverter and read/write parameter values using a user program. For further details,
refer to the instruction manual (detailed).
· Conforming standard: EIA Standard RS-485
· Transmission format: Multi-drop link
· Communication speed: Maximum 19200 bps
· Overall extension: 500m
CAUTION
Do not plug the connector to a computer LAN board, fax modem socket,
telephone modular connector etc. As they are different in electrical
specifications, the inverter may be damaged.
