Determine whether the FANUC I/O link is established.
Turn on the power to the Power Mate and the slave of the FANUC I/O link
(such as an I/O card or I/O unit). After the Power Mate i screen has
appeared, turn off only the power to the Power Mate i. If a communication
alarm is issued by the slave unit (the red LED lights), the FANUC I/O link
has already been established.
(1)When the FANUC I/O link has not yet been established
D Slave unit allocation error on the Power Mate
³ Refer to the PMC documentation or “Power Mate–MODEL
i–D/H Connection Manual (Function)” (description of the
FANUC I/O link function in “PMC Interface”) to set the slave
D Faulty cable contact
³ Make sure that the Power Mate connector is JD1A1 and that the
slave connector is JD1B. Alternatively, after turning the power
off, disconnect the cable, then connect it again.
D Wrong cable
³ The cable used for the FANUC I/O link function features pins
that are not connected straight through. For example, pin 1 of
one connector is connected to pin 3 of the other connector.
Check the connection.
D Defective Power Mate or slave unit
³ Replace the Power Mate or slave unit.
(2)When the FANUC I/O link has already been established
